Aftermarket 252717 High-Pressure Hose
This page describes an aftermarket high-pressure lubrication hose that cross-references the Lincoln 252717. Lincoln is a trademark of its respective owner. This is an aftermarket hose, not manufactured, sponsored, or endorsed by Lincoln. 252717 designations are for cross-reference identification only. The hose is a high-pressure feed line for progressive and multi-line centralized lubrication systems, supplied as an unfilled 200 ft coil.
Construction
The hose uses a nylon inner tube for chemical resistance to petroleum lubricants. A high-tensile braid reinforcement provides pressure containment. An abrasion-resistant polyurethane outer cover with weather resistance completes the three-layer build.

Where This Hose Fits
This hose works as a main distribution feed line for progressive systems and high-pressure supply networks. It connects pump-to-distribution runs on construction, mining, and agricultural machinery. It is compatible with petroleum lubricants, synthetic oils, and standard greases depending on system requirements.
On a typical machine, this size of hose runs from the pump outlet to the first divider block, and then continues as the main supply spine along the frame. Branch lines to individual points usually step down to smaller tubing, so this hose is ordered for the trunk runs rather than the final connections. Because it ships as one continuous 200 ft coil, a single coil can often supply several machines, leaving cut ends to be terminated with your own nuts and ferrules.
Installation Notes
Respect the 95 mm minimum bend radius; tighter routing kinks the hose and shortens life. Route away from sharp edges and hot surfaces. Cut squarely with proper hose cutters. Confirm fittings match the 5/16 inch OD before ordering nuts and ferrules. For system integration guidance, see progressive lubrication systems.
What to Confirm Before Ordering
Confirm ID 1/8 inch and OD 5/16 inch match your fittings. Confirm system pressure is within 4,000 psi continuous. Confirm temperature range covers your environment. Confirm you need a full 200 ft coil or cut lengths. Review grease pump and heavy equipment lubrication system options. If you are unsure about cut lengths or fitting compatibility, contact the team.
Frequently Asked Questions
What pressure is this hose rated for?
It is rated for 4,000 psi continuous working pressure. That covers most progressive and multi-line centralized lubrication feed applications.
Is the hose supplied grease-filled?
No, this hose is supplied unfilled. You fill it during system operation with your selected lubricant.
What is the minimum bend radius?
The minimum bend radius is 95 mm. Routing below that radius kinks the hose and shortens life.
What fittings does this hose use?
Fittings must match the 5/16 inch OD hose size. Nuts and ferrules are ordered separately based on your system.
What length is the hose supplied in?
The standard supply is a 200 ft coil. You can cut the coil to the lengths your system needs.
What fluids can this hose carry?
It carries petroleum lubricants, synthetic oils, and standard greases. Confirm fluid compatibility with your system requirements.
Can it replace my original hose?
Confirm ID, OD, and pressure rating first. If those match, the hose can serve the same feed line.
Is this hose for indoor or outdoor use?
The polyurethane cover is weather resistant. It can be routed in both indoor and outdoor installations.
How should I cut this hose?
Use a square cut with proper hose cutters. A clean square cut helps fittings seat correctly.
