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

Product Description

The PARKER 821FR-6-GRN-RL is a push-on air hose designed for compressed air distribution in industrial and trade service applications. With a 3/8 inch inside diameter and a 300 psi working pressure rating, this hose handles the demands of pneumatic tool connections, compressor drops, and shop air systems. The synthetic rubber construction provides flexibility across a wide service temperature range of -40 degrees F to 212 degrees F. It ships from a 575-foot coil and is priced and cut in 1-foot increments with a 25-foot minimum cut length, making it well suited for custom-length runs on the job site or in the shop.

This hose is commonly installed in commercial and industrial facilities, automotive shops, manufacturing environments, and mechanical rooms wherever push-on fittings and flexible compressed air drops are required. The green color coding aids in line identification when multiple hose types are routed in the same area. Plumbers, HVAC technicians, pipefitters, and general maintenance mechanics regularly work with this style of hose when building or maintaining pneumatic distribution systems. The push-on design eliminates the need for clamps or crimped end fittings at the hose-to-fitting connection.

Key Features

• 3/8 inch inside diameter with 0.63 inch outside diameter for consistent push-on fitting engagement
• 300 psi working pressure rating suitable for standard shop air systems
• Synthetic rubber construction resists abrasion and maintains flexibility under pressure
• Wide service temperature range: -40 degrees F to 212 degrees F
• Green color for easy visual identification in multi-line installations
• Cut-to-length from a 575-foot coil in 1-foot increments, 25-foot minimum order

Compatibility

Designed for use with standard push-on air fittings sized for 3/8 inch ID hose in compressed air service applications. No end connections are included; this is bulk hose sold by the foot.

Installation Notes

Installation should be performed by a qualified mechanic or pipefitter familiar with compressed air systems and applicable safety standards. Always depressurize and isolate the air supply before connecting or disconnecting hose segments. Verify that all push-on fittings are fully seated and rated for the system working pressure before returning the line to service. Do not exceed the 300 psi working pressure rating of the hose.
