Parker 7212-251BK Push-on Air Hose 1/4 in Id 300 Psi Black

Product Description

The PARKER 7212-251BK is a push-on air hose designed for compressed air and pneumatic service in industrial and mechanical applications. Constructed 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. With a 1/4 inch inside diameter and 1/2 inch outside diameter, this hose is sold by the foot in cut-to-length increments with a 25-foot minimum cut length from a 700-foot coil. No end connections are installed — field termination with compatible push-on fittings is standard practice. HVAC technicians, plumbers, and industrial mechanics install this hose in air-tool, pneumatic control, and general compressed air service lines.

This hose is suited for residential and commercial pneumatic systems where a lightweight, flexible black nitrile hose is required. Typical applications include air-tool supply lines, compressor outlet runs, and pneumatic control tubing. The push-on design eliminates the need for clamps or crimped ends during assembly, making it practical for rapid field assembly and service work. The 700-foot coil format supports shop fabrication and service vehicle stocking for high-volume users requiring cut-to-length flexibility.

Compatibility

Designed for use with standard push-on pneumatic fittings sized for 1/4 inch ID hose in compressed air and low-pressure pneumatic control applications.

Installation Notes

Installation is performed by qualified mechanics or HVAC technicians familiar with compressed air system assembly. Always depressurize and lock out the compressed air supply before disconnecting or replacing hose sections. Verify that all push-on fittings are fully seated and rated for the system working pressure before returning the line to service. Follow applicable facility safety and compressed air system codes when routing or securing hose runs.
