Parker 821-8-RL Push-on Air Hose 1/2 in Id 300 Psi

Product Description

The PARKER 821-8-RL is a push-on air hose designed for compressed-air distribution in industrial and trade service environments. It features a 1/2 inch inside diameter and a 300 psi working pressure rating, making it suitable for moderate- to high-demand pneumatic applications. Constructed from synthetic rubber, the hose handles a wide operating temperature range of -40 degrees F to 212 degrees F. No end connections are included — the push-on design allows fittings to be seated without clamps or crimps. This hose is sold by the foot in cut-to-length increments, with a 25-foot minimum cut and a total coil length of 240 feet.

This hose is used in shop air systems, pneumatic tool supply lines, and general compressed-air plumbing in residential, commercial, and light industrial settings. Its synthetic rubber construction resists weathering and maintains flexibility across a broad temperature range, which suits both indoor and outdoor runs. It is appropriate for HVAC, plumbing, and mechanical contractors who need field-cut hose lengths for custom pneumatic installations. The 1/2 inch ID sizing is a common choice for air supply lines feeding tools and equipment with moderate flow requirements.

Installation Notes

Installation is typically performed by mechanical, HVAC, or plumbing technicians working on compressed-air distribution systems. Depressurize and lock out the air supply before cutting or connecting hose segments. Use a clean, straight cut to ensure a proper push-on fitting seat. Verify that working pressures and temperatures of all system components are compatible before commissioning the line.
