Parker 302-20 Hydraulic Hose 1-1/4 in Id 1800 Psi

Product Description

The PARKER 302-20 is a high-pressure hydraulic hose designed for demanding fluid-power applications in mobile and industrial equipment. Built with a 1-1/4 inch inner diameter and a rated working pressure of 1,800 psi, this hose is constructed from synthetic rubber and meets multiple international and domestic standards including EN 853 TYPE 2SN, ISO 1436-1 TYPE 2SN, SAE J517 100R2AT, and SAE J1942. It is sold in 1-foot increments with a 5-foot minimum cut length and comes as a 55-foot total coil. Licensed hydraulic technicians and industrial maintenance professionals are the typical installers.

This hose is suited for hydraulic systems operating across a wide temperature range, from -40 degrees F to 250 degrees F. Typical applications include mobile hydraulic circuits on construction, agricultural, and material-handling equipment, as well as stationary industrial power units. The -20 hose size designation corresponds to a 1-1/4 inch ID, making it appropriate for high-flow, moderate-to-high pressure hydraulic lines where flexible routing is required.

Installation Notes

Hydraulic hose installation should be performed by qualified hydraulic technicians. Always depressurize and de-energize the hydraulic system completely before removing or installing hose assemblies. Use proper hose-cutting and crimping equipment rated for the hose series to ensure leak-free fittings. Inspect the completed assembly for correct routing, minimum bend radius compliance, and secure fitting engagement before returning the system to service.
