Parker 7212-381GY Push-on Air Hose 3/8 in Id 300 Psi Gray

Product Description

The PARKER 7212-381GY is a push-on air hose constructed from Buna-N (nitrile rubber) and sold in cut-to-length increments from bulk coil stock. It carries a 3/8 inch inside diameter and a 5/8 inch outside diameter, with a working pressure rating of 300 psi. The hose handles a service temperature range of -40 degrees F to 212 degrees F, making it suitable for demanding shop-air, pneumatic tool, and general compressed-air distribution applications. Licensed HVAC technicians, plumbers, industrial mechanics, and pneumatic system installers use this hose when routing flexible air lines in tight or variable-length installations where a push-on fitting connection is preferred over crimped or swaged ends.

This hose is suited for residential and commercial pneumatic air distribution, shop-air supply lines, and compressor outlet runs where flexibility and pressure resistance are required. The cut-to-length format allows technicians to size runs precisely on site, reducing waste. The gray nitrile construction resists oil, grease, and common shop fluids, making it appropriate for both clean-air and lightly contaminated environments. A minimum cut length of 25 feet applies per order increment, with total coil stock available up to 700 feet per coil.

Key Features

• Push-on hose design for use with compatible push-on air fittings — no crimping tools required
• 300 psi working pressure rating for standard compressed-air service
• Wide temperature range: -40 degrees F to 212 degrees F
• Buna-N (nitrile rubber) construction resists oil, grease, and petroleum-based fluids
• 28 InHg vacuum rating supports both pressure and light vacuum applications
• Sold in 1-foot increments from bulk coil; 25-foot minimum cut length per order

Compatibility

Designed for use with push-on style air fittings sized for 3/8 inch ID hose. No factory-installed end connections are included; compatible fittings are selected separately based on the application.

Installation Notes

Installation is typically performed by industrial mechanics, HVAC technicians, or pneumatic system specialists. Depressurize and lock out the compressed-air system completely before cutting or connecting hose sections. Ensure mating push-on fittings are rated for the same or higher working pressure as the hose. Cut hose ends square with a sharp hose cutter to achieve a proper seal when seating onto push-on fittings.
