Parker 7212-501BK Push-on Air Hose 1/2 in Id 300 Psi Black

Product Description

The PARKER 7212-501BK is a push-on air hose designed for compressed air distribution in industrial and commercial service environments. It features a 0.5 inch inside diameter and a 0.75 inch outside diameter, with a working pressure rating of 300 psi. The hose is constructed from Buna-N nitrile rubber, which provides resistance to petroleum-based oils and general shop fluids. Rated for temperatures from -40 degrees F to 212 degrees F, it handles the thermal demands of both indoor and outdoor compressed air systems. This hose is sold in 1-foot increments with a 25-foot minimum cut length from a 600-foot master coil, making it well suited for shops that need specific run lengths without waste.

This hose is used in pneumatic tool supply lines, air compressor distribution runs, and general-purpose compressed air systems in automotive, manufacturing, and maintenance environments. The push-on end connection style eliminates the need for clamps or ferrules at compatible push-on fittings, speeding up assembly on new installations and field repairs. It is appropriate for both permanent plumbing drops and semi-permanent hose runs where a clean, low-profile connection is preferred.

Key Features

• 0.5 inch ID and 0.75 inch OD for standard push-on fitting compatibility
• 300 psi working pressure rated for compressed air service
• Buna-N nitrile rubber construction resists petroleum-based oils and shop fluids
• Wide service temperature range: -40 degrees F to 212 degrees F
• 28 InHg vacuum rating supports light vacuum applications
• Sold by the foot in 25-foot minimum increments — no fixed reel lengths required

Compatibility

Designed for use with push-on style fittings sized for 0.5 inch ID air hose. No end connections are included; fitting selection depends on the specific push-on system used in the installation.

Installation Notes

Installation is typically performed by a pipefitter, millwright, or qualified maintenance technician. Depressurize and bleed down the air supply line completely before cutting or connecting hose. Push-on hose requires a clean, square cut at the end to seat properly against the fitting barb; use a sharp hose cutter rather than a blade knife to avoid deformation. Verify that system pressure does not exceed the 300 psi working pressure rating of this hose.
