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

Product Description

The PARKER 821FR-6-WHT-RL is a push-on air hose designed for compressed air distribution in industrial and trade environments. Built from synthetic rubber, it carries a 3/8 inch inside diameter and a 0.63 inch outside diameter, with a 300 psi working pressure rating. The hose is rated for service from -40 degrees F to 212 degrees F, making it suitable for a wide range of ambient and operational conditions. It is sold by the linear foot in 1-foot increments, with a 25-foot minimum cut length pulled from a 575-foot coil. No end connections are included. Licensed tradespeople and industrial maintenance technicians are the primary installers.

This hose is used in shops, mechanical rooms, and job sites where a flexible, cut-to-length compressed air supply line is needed. Its push-on design allows field assembly without crimping tools, suited for applications where hose barb fittings are already in place. The white color aids visibility in clean-room or light-colored equipment environments. It is appropriate for residential and light commercial pneumatic tool supply, air-operated controls, and general compressed air routing where a synthetic rubber construction is required for temperature and pressure performance.

Installation Notes

Installation is typically performed by licensed pipefitters, pneumatic system technicians, or qualified maintenance mechanics. Depressurize the compressed air system completely before cutting or connecting hose sections. Use a clean, straight cut perpendicular to the hose centerline to ensure a proper seal on push-on fittings. Follow applicable OSHA and ASME B31.1 guidelines for compressed air piping and hose assemblies.
