Parker 422-4-RL Hydraulic Hose 3250 Psi 0.25 Inch Id

Product Description

The PARKER 422-4-RL is a single-wire-braid hydraulic hose rated at 3,250 psi working pressure, designed for medium-pressure hydraulic fluid conveyance in industrial and mobile equipment applications. Built with a synthetic rubber tube and cover, this -4 hose size carries a 0.25 inch inner diameter and meets SAE J517 100R1AT and EN 853 1SN standards. It is sold by the foot in a 450-foot coil, with a minimum cut length of 25 feet. Hydraulic system technicians, fluid power specialists, and heavy equipment mechanics specify this hose for routing hydraulic lines where flexibility, pressure capacity, and temperature resistance are required.

The 422-4-RL is suited for mobile hydraulic systems, industrial machinery, and agricultural equipment where a compact hose diameter and moderate working pressure cover the majority of circuit requirements. The -40 degrees F to 212 degrees F temperature range makes it viable in both cold-climate outdoor equipment and standard shop environments. It is typically cut to length at the shop and terminated with appropriate bite-to-wire or swaged end fittings before installation. This hose is sold in 25-foot minimum increments from a 450-foot coil, priced per foot.

Compatibility

Designed as an OEM-style replacement or new-installation hose for medium-pressure hydraulic circuits in mobile and industrial equipment requiring a -4 (0.25 inch ID) single-wire-braid hose conforming to SAE J517 100R1AT or EN 853 1SN specifications.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and lock out the hydraulic system completely before cutting, removing, or replacing any hose section. Use appropriate hose cutting tools to ensure a clean square cut, and terminate with fittings rated for the hose series and working pressure. Follow SAE J1942 routing and clamping guidelines to prevent abrasion, excessive bending, and heat contact during operation.
