Parker 7212-251RD Push-on Air Hose 1/4 in Id 300 Psi Red

Product Description

The PARKER 7212-251RD is a push-on air hose designed for compressed air systems in industrial, commercial, and trade service environments. Built from Buna-N nitrile rubber, it carries a working pressure rating of 300 psi and handles temperatures from -40 degrees F to 212 degrees F. The hose measures 0.25 inches inside diameter and 0.5 inches outside diameter. It is sold cut-to-length from a bulk coil, making it well suited for shops, job sites, and service fleets that need custom hose runs without pre-terminated fittings. Pneumatic technicians, HVAC mechanics, and general service plumbers are the typical installers.

This hose is used in pneumatic tool supply lines, compressed air distribution systems, and general shop-air applications where flexibility and pressure retention across a wide temperature range are required. The -40 degrees F cold-temperature rating makes it appropriate for outdoor or refrigerated-space installations. The cut-to-length format allows precise runs to be built on site. This item is priced per 1-foot increment with a 25-foot minimum cut length and a 700-foot total coil length available per order.

Key Features

Compatibility

Designed for use with standard push-on pneumatic fittings sized for 0.25-inch inside diameter hose. No specific system or model compatibility data was provided for this SKU.

Installation Notes

Installation is typically performed by pneumatic or mechanical technicians. Depressurize and lock out the air supply before cutting or connecting hose. Use a clean, square cut and compatible push-on fittings rated for the system working pressure. Verify fitting retention after assembly by pressurizing slowly and inspecting for leaks before returning the line to service.
