Parker 7212-381BL Push-on Air Hose 3/8 in 300 Psi Blue

Product Description

The PARKER 7212-381BL is a push-on air hose designed for compressed air service in industrial, automotive, and trade applications. It features a 3/8 inch inside diameter and 5/8 inch outside diameter, with a 300 psi working pressure rating. The hose is constructed from Buna-N (nitrile rubber), which resists oil mist and moderate petroleum exposure common in shop-air environments. Rated for service from -40 degrees F to 212 degrees F, it handles both cold-weather outdoor installs and high-ambient shop conditions. It is sold in cut-to-length increments of 1 foot, with a 25-foot minimum cut length from a 700-foot master coil. Installation is typically performed by HVAC technicians, plumbers, pipefitters, and mechanical contractors.

This hose suits shop-air distribution lines, pneumatic tool drops, and compressor outlet runs in residential and light commercial settings. The push-on end connection style allows assembly without crimping equipment, making field cuts and custom-length runs straightforward. The blue color aids visual identification in multi-hose installations. With a 28 InHg vacuum rating, it is also suitable for light vacuum service alongside standard compressed air duty. Minimum order quantity is 25 feet per cut.

Installation Notes

Depressurize and lock out the air supply before cutting or connecting this hose. Push-on fittings should be fully seated to the fitting shoulder to ensure a leak-free connection. Inspect cut ends for squareness and remove any burrs before assembly. Follow applicable OSHA and ASME B31.1 guidelines for compressed air piping and hose installations.
