Parker 302-4-RL Hydraulic Hose 5800 Psi 0.25 Inch Id

Product Description

The PARKER 302-4-RL is a high-pressure hydraulic hose engineered for demanding fluid power applications. Built on the Series 302 platform, it features a 0.25 inch (1/4 inch) inner diameter and a working pressure rating of 5,800 psi. The hose construction uses synthetic rubber and conforms to SAE J517 100R2AT, EN 853 Type 2SN, and ISO 1436-1 Type 2SN standards. It handles a temperature range of -40 degrees F to 250 degrees F, making it suitable for both cold-start and high-cycle thermal environments. Licensed hydraulic technicians and mobile equipment mechanics install this hose in industrial and mobile hydraulic circuits.

This hose is suited for residential and commercial hydraulic systems, mobile equipment, agricultural machinery, and industrial fluid power lines where a -4 hose size (1/4 inch ID) and 5,800 psi working pressure are specified. It is sold in 1-foot increments with a 25-foot minimum cut length. Total coil stock length is 450 feet. This pricing and cut structure makes it practical for both service shops cutting to order and contractors managing bulk inventory. Always verify the end-fitting compatibility and pressure rating of all connected components before installation.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power system safety practices. Depressurize and bleed the hydraulic system fully before cutting, routing, or connecting hose assemblies. Use proper hose cutting and crimping equipment to ensure clean ends and leak-free fittings. Verify that all fittings, adapters, and connected components are rated at or above the hose working pressure before returning the system to service.
