Parker 821-12-RL Push-on Air Hose 3/4 in 250 Psi Ctl

Product Description

The PARKER 821-12-RL is a push-on air hose designed for compressed air distribution in industrial, commercial, and trade service environments. It features a 3/4 inch inside diameter and a synthetic rubber construction that supports a working pressure of 250 psi. The temperature range spans -40 degrees F to 212 degrees F, making it suitable for use in both cold-storage facilities and high-heat service bays. This hose is sold cut-to-length in 1-foot increments with a 20-foot minimum cut, allowing technicians and contractors to order exactly what a job requires without waste. It is installed by HVAC technicians, plumbers, pipefitters, and general industrial mechanics.

This hose is commonly used in shop air systems, pneumatic tool supply lines, and compressed air distribution runs in light industrial and commercial settings. The push-on end connection design allows for quick assembly with compatible push-on fittings without the need for clamps or crimped ferrules. The 3/4 inch ID is a standard size for higher-flow pneumatic applications where smaller hose bores would create pressure drop across long runs or at high-demand tools. The total coil length available is 200 feet per coil, with orders fulfilled from that coil stock in cut lengths.

Installation Notes

Installation should be performed by a qualified technician or mechanic familiar with compressed air system safety. Depressurize and lock out the air supply before making any hose connections or disconnections. Verify that all fittings and connectors are rated at or above the 250 psi working pressure of this hose. Do not exceed the rated working pressure or temperature limits in any installed application.
