Product Description

The PARKER 821FR-12-GRN-RL is a push-on air hose designed for compressed air distribution in industrial, commercial, and trade service applications. Built from synthetic rubber, it accepts push-on fittings without the need for clamps or ferrules, making connections fast and straightforward. The hose carries a 250 psi working pressure rating and handles a temperature range of -40 to 212 degrees F. It has a 3/4 inch inside diameter and a 1.03 inch outside diameter. This hose is sold by the foot in 1-foot increments with a 20-foot minimum cut length, pulled from a 200-foot source coil.

This hose is suited for pneumatic tool supply lines, air compressor drop lines, and general-purpose compressed air runs in shop, mechanical, and field service environments. The green color aids in line identification on busy installations with multiple hose types. Licensed HVAC technicians, plumbers, and general mechanics commonly use this hose where a reliable, moderate-pressure air supply connection is required. It performs across a wide temperature range, making it practical for both indoor shop use and outdoor seasonal work.

Installation Notes

Installation is typically performed by mechanics, HVAC technicians, or plumbers with experience in compressed air system assembly.
