Parker 821FR-6-BLK-RL Push-on Air Hose 3/8 in 300 Psi

Product Description

The PARKER 821FR-6-BLK-RL is a push-on air hose designed for compressed air service in industrial and trade applications. With a 3/8 inch inside diameter and a 300 psi working pressure rating, this hose handles the demands of pneumatic tools, air-powered equipment, and general shop or field air lines. The hose is constructed from black synthetic rubber, which resists weathering, abrasion, and flexing under repeated use. It is rated for a temperature range of -40 degrees F to 212 degrees F, making it suitable for both cold-weather outdoor installations and heated indoor environments. This is a cut-to-length product, priced per 1-foot increment with a 25-foot minimum cut length.

This hose is used in commercial, industrial, and trade settings where a reliable, flexible compressed air supply line is needed. Typical applications include connecting compressors to distribution headers, running air lines in service bays, and supplying pneumatic tools on job sites. The push-on fitting style allows fast assembly without clamps when paired with compatible push-on fittings. HVAC technicians, plumbers, and general mechanical contractors commonly use this type of hose in both permanent and temporary air supply runs. The 575-foot total coil length makes it practical for large projects or shop inventory stocking.
