Parker 201-6-RL-250 Hydraulic Hose 2250 Psi 5/16 in Id

Product Description

The PARKER 201-6-RL-250 is a Series 201 synthetic rubber hydraulic hose rated for a 2,250 psi working pressure. It features a 5/16 inch inner diameter and is sold in 1-foot increments from a 250-foot coil, with a 20-foot minimum cut length. The hose operates across a wide temperature range of -40 degrees F to 302 degrees F, making it suitable for demanding hydraulic circuits in mobile equipment, industrial machinery, and air brake systems. Licensed HVAC, plumbing, and fluid power technicians working on hydraulic and pneumatic lines will find this hose meets common OEM replacement and new-install specs.

The 201-6-RL-250 is designed for hydraulic and air brake line applications where DOT and SAE compliance is required. Its black synthetic rubber construction resists abrasion, oil, and environmental exposure in both shop and field environments. Typical applications include mobile hydraulic systems, truck and trailer air brake lines, and industrial fluid transfer circuits. The hose is cut to length on order, giving installers flexibility to fit routing requirements without excess material waste.

Compatibility

Designed as an OEM-style replacement or new-installation hose for hydraulic and air brake systems requiring a size -6, 5/16 inch ID hose rated to 2,250 psi and compliant with DOT FMVSS 106, SAE J1402, and SAE J517 100R5 specifications.

Installation Notes

Installation should be performed by a qualified fluid power or hydraulic technician familiar with hose assembly and routing practices. Depressurize and isolate the hydraulic or pneumatic circuit fully before cutting or connecting hose. Use proper hose-cutting tools to ensure a clean, square end before attaching swaged or reusable fittings. Follow SAE and DOT guidelines for bend radius, clamp spacing, and fitting torque as specified by the fitting manufacturer.
