Parker 422-8-RL Hydraulic Hose 0.5 in Id 2325 Psi

Product Description

The PARKER 422-8-RL is a single-wire braid hydraulic hose engineered for medium-pressure fluid power applications. It carries a -8 hose size designation with a 0.5-inch inner diameter and a working pressure rating of 2,325 psi. The hose body is constructed from synthetic rubber, providing flexibility and resistance to petroleum-based hydraulic fluids across a wide service temperature range of -40 degrees F to 212 degrees F. This hose is priced and cut in 1-foot increments from a 400-foot coil, with a 25-foot minimum cut length. It is a standard specification used by hydraulic system technicians, equipment mechanics, and industrial maintenance professionals.

The 422-8-RL suits mobile and stationary hydraulic circuits where moderate working pressures are required. Typical installations include construction equipment, agricultural machinery, industrial presses, and plant utility lines. The synthetic rubber construction handles standard hydraulic oils and is suited for both indoor and outdoor environments where temperature extremes are common. The black outer cover resists abrasion and weathering under normal service conditions. Technicians selecting hose for OEM fabrication or field repair work will find the Series 422 a broadly applicable medium-pressure solution.

Compatibility

Designed as a Series 422 single-wire braid hydraulic hose meeting EN 853 Type 1SN, ISO 1436-1 Type 1SN, SAE J517 100R1AT, and SAE J1942 specifications, making it interchangeable with other hoses built to those same standards in -8 hose size applications.

Installation Notes

Hydraulic hose installation and replacement should be performed by a qualified hydraulic technician or certified mechanic. Depressurize and bleed the hydraulic system fully before cutting or disconnecting any hose assembly. Use the appropriate hose cutter to achieve clean, square-cut ends, and confirm fitting compatibility with the -8 hose size before crimping or field assembly. Follow equipment manufacturer torque and assembly specifications for end fittings, and inspect the completed assembly for leaks before returning the system to service.
