Oil Can Discharge Spout Oil Can Discharge Spout (Rigid / Fixed)
The STAR Rigid Oil Can Discharge Spout is a zinc-plated steel replacement spout designed for hand pump oilers and oil cans. It threads directly onto any standard oil can with a 1/4" UNEF x 32 TPI female connection.
A precision-bent discharge tip at the end of the spout directs oil flow at a controlled angle, reducing drips and allowing accurate placement into tight lubrication points such as bearing oil holes, hinge pins and machine slideways.
Available in six lengths from 4" (100 mm) to 9" (225 mm), the zinc plating resists corrosion from workshop oils, cutting fluids and light solvents. The rigid steel construction holds its shape under repeated use, unlike plastic alternatives that crack or deform.
Suited for machinists, maintenance technicians, automotive workshops and anyone who needs controlled, spill-free oiling on lathes, milling machines, CNC equipment, textile machinery, sewing machines and agricultural equipment.
Rugged Build Quality
- Zinc-plated steel construction provides corrosion resistance against workshop oils, cutting fluids and light solvents.
- Precision-bent discharge tip angles oil flow for controlled delivery into recessed fittings and tight access points.
- 1/4" UNEF x 32 TPI thread is the industry standard, fitting all standard pump oilers and lever-type oil cans.
- Six size options from 4" (100 mm) for close-quarters work to 9" (225 mm) for deep-reach applications.
- Interchangeable design allows swapping between rigid and flexible spouts on the same oil can.
- Smooth internal bore maintains consistent oil flow without turbulence or blockage from burrs.
- Rigid steel body holds its shape permanently, unlike PVC or rubber alternatives that soften and droop over time.
How the Rigid Spout Works
The rigid discharge spout is a simple, effective accessory that converts your oil can's pumping action into precise, targeted lubrication:
- Thread on: Screw the spout clockwise onto your oil can's female-threaded outlet (1/4" UNEF x 32 TPI). Hand-tighten until snug. No tools or thread sealant required for a drip-free connection.
- Position: Place the precision-bent discharge tip directly against the oil hole, bearing port or lubrication point. The angled tip lets you reach recessed fittings without tilting the entire oil can.
- Dispense: Pump or squeeze the oil can. Oil travels through the rigid steel bore and exits at the bent tip in a controlled stream. The narrow discharge end concentrates flow to prevent over-oiling and waste.
Because the spout is rigid steel, it does not flex or move during pumping. This gives you repeatable aim on precision points such as clock mechanisms, sewing machine shuttles, lathe ways and small motor bearings where even a single extra drop causes problems.

Buying Guide: Choosing the Right Rigid Spout Length
Selecting the correct spout length depends on how deep the lubrication point sits inside the equipment and how much clearance you have around it.
Short Spouts (4" and 5") for Close-Quarters Work
Use the RS-OC-4 or RS-OC-5 when the oil point is within arm's reach and you need compact handling. Sewing machines, clock mechanisms, small electric motors and bench-top equipment benefit from shorter spouts because they reduce leverage on the oil can body and give finer control over single-drop delivery. Shorter spouts also store more easily inside tool drawers.
Medium Spouts (6" and 7") for General Workshop Use
The RS-OC-6 and RS-OC-7 are the most versatile lengths for automotive workshops, machine shops and general maintenance. They reach door hinges, lathe ways, milling machine slides and conveyor bearings without requiring you to position the oil can at an awkward angle. If you only stock one size, 6" covers the widest range of applications.
Long Spouts (8" and 9") for Deep-Reach Applications
The RS-OC-8 and RS-OC-9 reach lubrication points buried inside machinery guards, behind panels or deep within engine compartments. Tractor linkage pins, industrial gearbox oil holes and CNC machine spindle bearings often require 8" or 9" reach. The rigid steel body ensures the spout does not deflect under its own weight at these longer lengths.
Rigid vs Flexible Spout
Choose rigid when the lubrication point is accessible in a straight or near-straight line and you need repeatable aim. Choose flexible when you must route around obstacles, reach behind panels or oil fittings that are not in line-of-sight. Both types share the same 1/4" UNEF x 32 TPI thread, so you can keep one of each and swap as needed.

Frequently Asked Questions: Rigid Oil Can Discharge Spout
What is a rigid oil can discharge spout?
A rigid oil can discharge spout is a straight, solid steel tube that threads onto the outlet of a hand pump oiler or oil can to direct oil precisely into lubrication points. Unlike flexible spouts that bend to reach around obstacles, a rigid spout holds its shape permanently. The STAR RS-OC series is made from zinc-plated steel with a precision-bent discharge tip that angles the oil stream for controlled delivery into bearing oil holes, hinge pins, machine slideways and other tight access points.
What material is the STAR rigid spout made from?
The STAR rigid spout is manufactured from zinc-plated steel. The zinc plating provides a corrosion-resistant barrier against workshop oils, cutting fluids, penetrating oils and light solvents. Steel construction ensures the spout maintains its shape over years of daily use without cracking, softening or deforming. The internal bore is smooth-finished to prevent oil flow disruption from burrs or rough surfaces.
What is the bend angle on the rigid discharge tip?
The discharge end features a slight precision bend that angles the oil stream away from the straight axis of the spout body. This bend allows you to direct oil into recessed fittings, oil holes set at an angle, and lubrication points that are not perfectly aligned with the spout approach. The bend is factory-set during manufacturing and should not be adjusted by the user, as bending zinc-plated steel risks cracking the plating and exposing bare metal to corrosion.
What thread size does the rigid spout use?
The thread is 1/4" UNEF x 32 TPI (Unified National Extra Fine, 32 threads per inch). This is the industry-standard thread for oil can spouts worldwide. It fits all standard pump oilers, lever-type oil cans, pistol-type oil cans and squeeze-type oilers that have a female-threaded spout outlet. The fine thread pitch creates a tight seal without requiring thread sealant tape in normal use.
What sizes does the rigid spout come in?
The STAR RS-OC series is available in six lengths: 4" (100 mm), 5" (125 mm), 6" (150 mm), 7" (175 mm), 8" (200 mm) and 9" (225 mm). Shorter spouts (4"-5") suit close-quarters precision work on sewing machines, clocks and small motors. Medium lengths (6"-7") cover general workshop and automotive use. Longer spouts (8"-9") reach deep into machinery guards, engine compartments and industrial gearbox housings.
When should I choose a rigid spout over a flexible one?
Choose rigid when the lubrication point is accessible in a straight or near-straight line from where you hold the oil can. Rigid spouts give you repeatable aim because they do not move during pumping. They are better for precision single-drop oiling on clock mechanisms, instrument pivots and sewing machine shuttles. Choose a flexible spout when you need to route around obstacles, reach behind panels or oil fittings that are not in your line of sight.
Can I use the rigid spout on any brand of oil can?
Yes, the 1/4" UNEF x 32 TPI thread is an industry standard shared across virtually all oil can manufacturers. The STAR rigid spout fits oil cans from any brand that uses this standard female-threaded outlet. If your oil can currently has a spout attached, unscrew it and check the thread. If it matches 1/4" UNEF (approximately 6.35 mm outer diameter with very fine threads), the STAR spout will fit.
How do I attach the rigid spout to my oil can?
Thread the spout clockwise into the female outlet on your oil can by hand until snug. No tools are needed. Do not over-tighten, as this can damage the fine threads. The connection should be finger-tight only. If you notice oil seeping at the thread junction during use, remove the spout, clean both threads of any oil residue or debris, and re-thread. Teflon tape is not normally required but can be used if the threads are slightly worn.
Can I use the rigid spout for gear oil or thicker lubricants?
Yes, but flow rate will be slower with higher-viscosity oils. The rigid spout's internal bore handles machine oil, cutting oil, penetrating oil, 3-in-1 oil, sewing machine oil and light hydraulic oil without restriction. For thicker gear oils (ISO VG 220 and above), you may need to pump harder and allow more time for the oil to travel through the spout. Extremely thick greases are not suitable for oil can spouts; use a grease gun instead.
How do I prevent the rigid spout from rusting?
The zinc plating provides built-in corrosion protection, but proper storage extends spout life significantly. After use, wipe the exterior with a clean rag to remove oil drips that attract dust. Store the oil can with spout attached in a dry location away from water spray or condensation. If the zinc plating becomes scratched or worn through to bare steel, apply a thin coat of machine oil to the exposed area. Replace the spout if rust develops inside the bore, as rust flakes can contaminate your oil and block the discharge tip.
How do I clean a clogged rigid spout?
Soak the spout in a light solvent (mineral spirits, kerosene or penetrating oil) for 10-15 minutes, then push a thin wire or pipe cleaner through the bore from the threaded end. Dried oil residue, dust and metal particles are the most common causes of blockage. For stubborn clogs, use compressed air blown from the threaded end after soaking. Avoid using sharp tools that could scratch the internal bore. Regular cleaning every few months prevents buildup from hardening into a permanent blockage.
Does spout length affect oiling precision?
Yes. Shorter spouts give finer control for single-drop precision work because there is less distance between your hand and the discharge point. A 4" spout on a pump oiler lets you place one drop exactly where needed on a clock pivot or sewing machine shuttle. Longer spouts (8"-9") sacrifice some fine control for reach, but the rigid steel body still holds aim far better than a flexible alternative at the same length. For most workshop tasks, 6" balances precision and reach.
Can I use the rigid spout for precision oiling on small bearings?
Yes, the rigid spout is ideal for precision bearing lubrication. The narrow discharge bore and precision-bent tip concentrate oil flow into a small area, allowing you to deliver measured amounts into miniature ball bearings, instrument pivots, electric motor bushings and sealed bearing oil ports. Use a short spout (4" or 5") with a pump oiler for maximum single-drop control. Count pump strokes to meter exact oil volume per the bearing manufacturer's specification.
Is the zinc plating safe for food-grade oil applications?
Zinc-plated steel is not certified for direct food contact in most jurisdictions. If you are dispensing food-grade oil (such as food machinery lubricant or NSF H1 rated oil) into equipment that contacts food products, check your local food safety regulations regarding zinc-plated dispensing equipment. For non-food industrial applications, the zinc plating is fully safe and does not contaminate standard machine oils, cutting fluids or hydraulic oils.
