Parker 422-12-RL Hydraulic Hose 3/4 in Id 1525 Psi

Product Description

The PARKER 422-12-RL is a -12 hose size hydraulic hose with a 3/4 inch inner diameter, rated for a working pressure of 1,525 psi. Built from synthetic rubber, it is designed for use in hydraulic fluid transmission systems in mobile and industrial equipment. The hose meets EN 853 Type 1SN, ISO 1436-1 Type 1SN, SAE J517 100R1AT, and SAE J1942 standards. It is sold in 1-foot increments with a 20-foot minimum cut length and ships from a 230-foot coil. The temperature range spans -40 degrees F to 212 degrees F, making it suitable for most standard hydraulic service environments. Licensed fluid power technicians and hydraulic system mechanics are the typical installers.

This hose is suited for general-purpose hydraulic applications in agricultural, construction, and industrial machinery where a single-wire braid reinforced hose is specified. The 422 Series is a common OEM and aftermarket replacement choice where SAE 100R1AT or EN 853 1SN hose is required. It is compatible with petroleum-based hydraulic fluids, and its black synthetic rubber cover resists oil, abrasion, and weathering in typical outdoor service conditions. The 20-foot minimum cut length is standard for this SKU, and the full coil length is 230 feet.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic system mechanic. De-pressurize and isolate the hydraulic circuit fully before cutting or replacing hose. Use proper hose cutting tools to ensure a clean, square cut, and verify that all end fittings are rated for the system working pressure before assembly. Follow IFPS and equipment manufacturer guidelines for hose routing, bend radius, and securing to prevent chafing and pressure fatigue.
