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

Product Description

The PARKER 821-6-RL is a push-on air hose designed for compressed air distribution in industrial and trade service environments. Built from black synthetic rubber, this hose has a 3/8 inch inside diameter and a 0.63 inch outside diameter, with a rated working pressure of 300 psi. It is sold in cut-to-length increments of 1 foot with a minimum cut length of 25 feet from a 350-foot master coil. The temperature range of -40 to 212 degrees F makes it suitable for year-round use in both indoor and outdoor installations. Licensed plumbers, HVAC technicians, and industrial maintenance mechanics are the typical installers.

This hose is used wherever a push-on style air hose connection is required without the need for end fittings pre-installed at the factory. Common applications include shop air lines, pneumatic tool supply runs, compressor outlet lines, and general compressed air distribution in light commercial and industrial settings. The cut-to-length format allows technicians to size the hose precisely for each run, reducing waste and avoiding excess slack in finished installations.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified industrial maintenance technicians. Depressurize and lock out the air supply completely before cutting, routing, or connecting this hose. Use a clean, straight cut to ensure full seating on push-on barb fittings and verify the hose is seated past the barb retaining bead before pressurizing. Follow applicable OSHA compressed air safety requirements and any local codes governing pneumatic system installation.
