Parker 7212-251BL Push-on Air Hose 1/4 in Id 300 Psi Blue

Product Description

The PARKER 7212-251BL is a push-on air hose designed for compressed air lines in industrial and trade service environments. It features a 0.25 inch inside diameter and a 0.5 inch outside diameter, with a 300 psi working pressure rating. The hose is constructed from Buna-N nitrile rubber, which provides resistance to oil, abrasion, and general shop-floor conditions. It operates across a temperature range of -40 degrees F to 212 degrees F, making it suitable for year-round use in both indoor and outdoor installations. This hose is sold in cut-to-length increments and is typically installed by HVAC technicians, plumbers, pipefitters, and general maintenance mechanics who need a durable, flexible air line solution.

This hose is suited for compressed air distribution in light industrial, commercial, and heavy-duty residential applications. The push-on end connection style allows for tool-free assembly with compatible push-on fittings, reducing installation time. The 0.25 inch ID is a common size for pneumatic tool supply lines and instrument air applications. It ships from a 700-foot coil with a 25-foot minimum cut length, allowing contractors to order the exact footage needed for a job rather than purchasing fixed-length assemblies. The blue color aids in quick identification in multi-hose installations.

Installation Notes

Installation should be performed by a qualified technician following applicable OSHA compressed air safety guidelines and local mechanical codes. Depressurize and lock out the air system completely before cutting or connecting hose. Use only push-on fittings rated at or above 300 psi and confirmed compatible with 0.25 inch ID hose. Avoid routing hose near sharp edges, high heat sources, or surfaces that exceed the 212 degrees F maximum temperature rating.
