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

Product Description

The PARKER 821FR-12-BLU-RL is a push-on air hose designed for compressed air service in industrial and trade applications. With a 3/4 inch inside diameter and a 1.0300 inch outside diameter, this hose handles working pressures up to 250 psi. The blue synthetic rubber construction resists a wide temperature range, rated from -40 degrees F to 212 degrees F. It is sold by the linear foot in 1-foot increments with a 20-foot minimum cut length from a 200-foot coil. HVAC technicians, plumbers, and general contractors install this hose in pneumatic tool supply lines, compressor outlets, and shop air distribution systems.

This hose is suited for residential and commercial job sites where a reliable, flexible air supply line is needed. The push-on end connection style eliminates the need for clamps or ferrules on compatible push-on fittings, making field assembly straightforward. Typical installations include air compressor drops, pneumatic control lines, and portable tool hoses. The blue color aids quick identification in multi-hose runs. No end connections are included; fittings must be sourced separately to match the application.

Installation Notes

Installation is typically performed by a licensed HVAC technician, pipefitter, or qualified mechanic. Always depressurize and lock out the air supply before cutting, connecting, or disconnecting hose sections. Use push-on fittings rated to match or exceed the 250 psi working pressure of this hose. Inspect cut ends for clean, square edges before seating onto fittings to ensure a secure, leak-free connection.
