Parker 7212-381GN Push-on Air Hose 3/8 in Id 300 Psi Green

Product Description

The PARKER 7212-381GN is a push-on air hose designed for pneumatic tool and compressed air service in trade and industrial environments. Built from Buna-N (nitrile rubber), it carries a 300 psi working pressure rating and handles a temperature range of -40 degrees F to 212 degrees F, making it suitable for year-round outdoor and shop use. The 3/8 inch inside diameter and 5/8 inch outside diameter sizing fits standard push-on pneumatic fittings without clamps or crimping. This hose is sold cut-to-length in 1-foot increments with a 25-foot minimum cut, drawn from a 700-foot coil. Plumbers, HVAC technicians, and general contractors commonly spec this hose for air supply lines, tool drops, and pneumatic control applications.

This hose is suited for residential and light commercial pneumatic systems where flexible, oil-resistant air line is required. The nitrile construction resists petroleum-based oils and common shop fluids, making it a reliable choice for compressor outlets, tool station drops, and portable air supply runs. Because it is sold by the foot from bulk coil stock, it works well for custom-length runs where precut assemblies are not practical. Installers working in mechanical rooms, service bays, or on job sites will find the cut-to-length format reduces waste on non-standard runs.

Compatibility

Designed for use with standard push-on pneumatic fittings sized for 3/8 inch ID air hose. No specific model or system compatibility data was provided; verify fitting series compatibility before ordering.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanics. Depressurize and lock out the compressed air supply before connecting or disconnecting hose sections. Push-on connections rely on barb-to-hose interference fit — ensure the fitting barb is fully seated and inspect for leaks before returning the system to service. Verify that the hose working pressure rating meets or exceeds the system operating pressure before installation.
