Parker 821FR-8-GRN-RL Push-on Air Hose 0.5 in Id 300 Psi

Product Description

The PARKER 821FR-8-GRN-RL is a push-on air hose designed for compressed air distribution in industrial and commercial service environments. It features a 0.5-inch inside diameter and a 0.78-inch outside diameter, with a 300 psi working pressure rating. Constructed from synthetic rubber, it handles a temperature range of -40 degrees F to 212 degrees F, making it suitable for demanding shop and field conditions. The hose ships cut-to-length from a 385-foot coil in 1-foot increments, with a 25-foot minimum cut. Installation requires no swaged or threaded end connections — push-on fittings seat directly onto the hose bead.

This hose is suited for compressed air supply lines in automotive shops, manufacturing facilities, and contractor job sites. The push-on construction eliminates the need for clamps or crimped ferrules at the fitting interface, speeding up assembly and reducing hardware costs. The green color coding aids in line identification in multi-hose installations. Sold by the foot, it is well suited for custom-length pneumatic runs where standard pre-assembled hose assemblies are not practical.

Installation Notes

This hose is typically installed by industrial maintenance technicians or pneumatic system installers. Depressurize and lock out the air supply before cutting or connecting any hose segment. Use a clean, straight cut to ensure a proper push-on fitting seat. Follow applicable shop air system codes and fitting manufacturer torque and insertion guidelines.
