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

Product Description

The PARKER 821FR-12-BLK-RL is a push-on air hose designed for compressed air distribution in industrial and mechanical service environments. With a 3/4 inch inside diameter and a 1.0300 inch outside diameter, it handles working pressures up to 250 psi and performs across a temperature range of -40 degrees F to 212 degrees F. Constructed from black synthetic rubber, the hose offers resistance to abrasion and weathering typical of shop and field air supply lines. It is sold in 1-foot increments with a 10-foot minimum cut length and is available from a 200-foot total coil. Minimum order quantity is 10 feet.

This hose suits compressed air applications in HVAC, plumbing, and general mechanical service settings. The push-on end connection style eliminates the need for clamps or ferrules during fitting attachment on compatible barb fittings, making it practical for production assembly and field service repairs. The 3/4 inch ID supports higher-volume air flow demands typical of larger pneumatic tools and equipment supply lines. Licensed tradespeople and shop technicians installing air distribution systems are the primary users.

Installation Notes

Installation is typically performed by HVAC technicians, pipefitters, or mechanical service professionals familiar with compressed air systems. Depressurize the air supply line completely before cutting, connecting, or disconnecting hose sections. Ensure barb fittings are clean and free of burrs before seating the hose to achieve a secure push-on connection. Verify that the completed assembly does not exceed the 250 psi working pressure rating under operating conditions.
