Oil Can Discharge Spout Oil Can Discharge Spout (Flexible)
The STAR FS-OC Flexible Oil Can Discharge Spout is a replacement spout for oil cans designed to reach confined lubrication points that rigid spouts cannot access.
Wire-braided PVC construction holds its shape once bent into position, delivering oil precisely to bearings, hinges and fittings behind panels, inside housings or around obstructions.
Available in five lengths from 5" (125 mm) to 9" (225 mm), with solid brass threaded ends that screw directly onto any standard oil can using the universal 1/4" UNEF x 32 TPI connection.
Suited to machinists, maintenance technicians and DIY mechanics who need controlled oil delivery in tight spaces on lathes, milling machines, sewing machines, door hinges and small engines.
Key Features
- Wire-braided PVC body provides flexibility with reinforced strength, resisting kinking and collapse under repeated bending.

Buying Guide: Choosing the Right Oil Can Spout
Selecting the correct spout depends on where you need to deliver oil and how often you change spouts. Here is how the FS-OC flexible spout compares to alternatives:
Flexible Spout vs Rigid Spout
A rigid zinc-plated steel spout delivers oil in a straight line with zero flex. Choose rigid when the oil port is visible and directly accessible. Choose the FS-OC flexible spout when you need to route around corners, behind panels or into recessed housings. Many workshops keep both types and swap them depending on the job.
Choosing the Right Length
Shorter spouts (5" and 6") give better control for shallow access points like sewing machine bearings, clock mechanisms and door hinges. Longer spouts (8" and 9") reach deep inside engine housings, behind CNC machine guards and into agricultural equipment linkages. The 7" is a versatile middle ground for general workshop use. If unsure, order a mixed-length assortment pack to cover all scenarios.
Brass Ends vs Zinc-Plated Ends
The FS-OC uses solid brass end fittings. Brass is softer than zinc-plated steel, which means it threads more smoothly and is less likely to cross-thread or strip the female port on your oil can. Brass also resists corrosion from oil exposure indefinitely. Zinc plating can eventually wear through on rigid spouts that are frequently removed and re-attached, exposing the steel underneath to rust.
Bulk Orders and Multi-Pack Options
For fleet maintenance operations, industrial distributors and workshop supply companies, we at STAR offer the FS-OC in 12-pack single-size boxes, mixed-length assortment kits, and custom OEM packaging with your brand logo. Spouts can also be bundled as oil can and spout combo kits or dual spout sets (one rigid + one flexible). Contact our export team for MOQ details and pricing.
When to Replace Your Spout
Replace a flexible spout when it no longer holds its bent position (the wire braiding has fatigued), when oil drips from the brass thread connection despite proper tightening, when the PVC has cracked or hardened from chemical exposure, or when internal blockage persists after cleaning. Inspect spouts during routine maintenance schedules. A worn spout causes dripping, imprecise oil delivery and potential slip hazards on workshop floors.
Frequently Asked Questions: Oil Can Discharge Spout (Flexible)
What is a flexible oil can discharge spout?
A flexible oil can discharge spout is a bendable tube that screws onto the threaded port of a pump oiler or hand oil can, allowing you to deliver oil around corners and into confined spaces. The STAR FS-OC uses wire-braided PVC with solid brass end fittings. Unlike a rigid steel spout that only delivers oil in a straight line, the flexible spout bends to any angle and holds that position while you pump. This makes it essential for oiling bearings behind motor housings, fittings inside machine guards, and any lubrication point that lacks direct line-of-sight access.
What is the difference between a rigid and flexible oil can spout?
A rigid spout is a straight or slightly bent zinc-plated steel tube for direct-access oiling. A flexible spout is a wire-braided PVC tube that bends and holds position for reaching confined areas. Use rigid when the oil port is visible and unobstructed. Use flexible when you need to route around obstacles, reach behind panels, or oil fittings deep inside equipment housings. Both use the same 1/4" UNEF x 32 TPI thread, so they are fully interchangeable on the same oil can.
What thread size do oil can spouts use?
The industry standard is 1/4" UNEF x 32 TPI (Unified National Extra Fine, 32 threads per inch). This thread is used by virtually all pump oiler and hand oil can manufacturers worldwide. The FS-OC flexible spout uses this exact thread specification, making it compatible with STAR oil cans and most other brands. If your oil can has a different thread (some older European models use DIN metric threads), check the port diameter before ordering.
Can I use a flexible spout on any oil can?
The FS-OC fits any oil can with a female 1/4" UNEF x 32 TPI threaded spout port, which covers the vast majority of pump oilers and lever-type oil cans sold globally. This includes all STAR oil cans, and most other manufacturers' models that follow the same international thread standard. If your oil can currently has a rigid spout that screws in, the flexible spout will fit the same port. Simply unscrew the rigid spout and screw in the FS-OC by hand until snug.
How do I attach a flexible spout to my oil can?
Screw the brass threaded end of the FS-OC into the female spout port on your oil can by hand, turning clockwise until finger-tight. Do not use pliers or wrenches, as over-tightening can damage the brass threads or the oil can port. The brass-to-brass (or brass-to-steel) contact creates a sufficient seal without thread tape in most cases. If you notice minor dripping at the connection after extended use, wrap one layer of PTFE (Teflon) tape around the male thread before re-attaching.
Does the flexible spout hold its bent position?
Yes, the wire braiding inside the PVC wall gives the FS-OC positional memory. Bend the spout to your desired angle and it stays there while you pump oil through it. This is the key advantage over plain rubber or silicone hoses, which spring back straight. You can re-bend the spout hundreds of times without the wire braiding losing its ability to hold shape. Over years of heavy use, the braiding may eventually fatigue, at which point the spout should be replaced.
What lengths are available for the flexible spout?
The FS-OC comes in five lengths: 5" (125 mm), 6" (150 mm), 7" (175 mm), 8" (200 mm) and 9" (225 mm). Shorter lengths suit shallow access points like sewing machine bearings and clock mechanisms. Longer lengths reach deep inside engine compartments, behind CNC machine guards and into agricultural equipment linkages. All five lengths use the same thread, material and brass end fittings.
How do I clean a clogged flexible spout?
Flush the spout with a light solvent (mineral spirits or kerosene), then blow compressed air through from the threaded end. If the blockage persists, soak the entire spout in solvent for 30 minutes to dissolve dried oil residue, then flush again. For stubborn internal buildup, a thin wire or pipe cleaner can dislodge solidified deposits. Prevent future clogging by wiping the spout tip after each use and storing the oil can with the spout pointing upward to avoid dust ingress.
Can I use the flexible spout with thicker oils like gear oil?
The FS-OC works best with light machine oils, penetrating oils, air tool oil and similar low-viscosity lubricants. Thicker oils (ISO VG 220+ gear oils, heavy cutting oils) will flow through the spout but require more pump pressure and deliver at a slower rate. The internal diameter of the spout limits flow for high-viscosity fluids. For very thick oils, a rigid spout with a larger bore provides better flow. The flexible spout is optimised for precision oiling with light to medium oils.
Is the flexible spout oil-resistant?
The wire-braided PVC material resists degradation from machine oils, mineral oils, penetrating oils, 3-in-1 oil and most light lubricants used in workshop environments. Prolonged exposure to aggressive solvents (acetone, MEK, strong degreasers) or certain synthetic fluids may cause the PVC to swell or harden over time. For standard oiling applications with petroleum-based or mineral-based oils, the FS-OC material lasts years without deterioration.
How often should I replace my flexible spout?
Replace the spout when it no longer holds its bent position, when the PVC shows visible cracking or hardening, or when oil drips from the brass connection despite proper tightening. Under normal workshop use (daily oiling of a few machines), a single FS-OC spout typically lasts 2-3 years. Heavy industrial use with frequent re-bending may shorten this to 12-18 months. Inspect the spout during routine maintenance and keep a spare on hand to avoid downtime.
Can I use the same spout for different oil types?
You can use one spout for multiple compatible oils (machine oil, penetrating oil, light lubricant) without issues. However, if you switch between oils that should not be mixed (such as mineral oil and synthetic oil on sensitive equipment), flush the spout with solvent between changes to prevent cross-contamination. For critical applications where even trace contamination matters, dedicate separate spouts to each oil type and label them.
Why does my oil can spout drip after pumping?
Dripping usually indicates a worn thread seal, a loose connection, or residual oil in the spout tip draining by gravity after you stop pumping. First, check that the spout is screwed in firmly (hand-tight). If dripping continues at the thread, apply one wrap of PTFE tape. If the drip comes from the tip, it is likely residual oil draining from the spout bore after pressure release. Wipe the tip after each use, or store the oil can with the spout pointing upward. A cracked spout body also causes mid-length dripping and requires replacement.
