Parker 7212-631RD Push-on Air Hose 5/8 in Id 300 Psi Red

Product Description

The PARKER 7212-631RD is a push-on air hose constructed from Buna-N nitrile rubber, designed for compressed air service in industrial, automotive, and mechanical trade applications. With a 5/8 inch inside diameter and a 29/32 inch outside diameter, it delivers a working pressure of 300 psi and handles temperatures from -40 degrees F to 212 degrees F. The hose is sold in cut-to-length increments of 1 foot with a 25-foot minimum cut, making it practical for custom runs without excess waste. Its red jacket aids quick identification in multi-hose installations.

This hose suits compressed air distribution in shops, production facilities, and service bays where a flexible, high-pressure line is needed between compressor manifolds, drops, or tool connections. Nitrile rubber construction resists petroleum-based oils and typical shop fluids, making it appropriate for environments where incidental fluid contact is likely. The 28 InHg vacuum rating extends its use to low-vacuum transfer applications. It is installed by pipefitters, millwrights, HVAC technicians, and general mechanical contractors working on compressed air systems.

Key Features

• Push-on fitting compatibility eliminates the need for clamps or crimped ferrules at assembly
• 300 psi working pressure rated for standard compressed air service
• Buna-N nitrile rubber construction resists petroleum oils and common shop fluids
• Wide temperature range of -40 degrees F to 212 degrees F suits both cold-climate and high-heat environments
• 28 InHg vacuum rating supports light vacuum transfer in addition to pressure service
• Red jacket provides fast visual identification in multi-line installations

Compatibility

Designed as a cut-to-length push-on air hose compatible with standard 5/8 inch push-on fittings used in industrial compressed air and light vacuum systems. No end connections are included; fitting selection depends on the specific application and connector standard in use.

Installation Notes

Installation is typically performed by pipefitters or mechanical technicians. Depressurize and lock out the compressed air system fully before cutting or connecting any hose segment. Use a clean, straight cut to ensure full seating against push-on fittings; angled or ragged cuts can compromise the seal. Verify that all fittings and hose ends are free of burrs and debris before assembly, and confirm the assembled system holds pressure before returning it to service.
