Value Collection 2332582521 Pneumatic Hose Coupler 1/4 Npt

Product Description

The VALUE COLLECTION 2332582521 is a brass pneumatic hose coupler designed for compressed-air tool and hose connections in automotive and industrial service environments. Built to the Tru-Flate automotive interchange standard, this six-ball coupler accepts a 1/4 inch MNPT fitting and accommodates hose with a 1/4 inch inside diameter. The all-brass construction resists corrosion and handles a maximum working pressure of 145 psi, making it a reliable choice for shop air systems, tire inflation, and general pneumatic tool hookups. Installed by automotive technicians, shop mechanics, and HVAC or plumbing tradespeople working with air-powered equipment, this coupler delivers a secure, leak-resistant connection in day-to-day service use.

This coupler is suited for residential and commercial shop environments where Tru-Flate automotive interchange fittings are the standard. Typical applications include connecting pneumatic impact wrenches, ratchets, blow guns, and inflation nozzles to shop air lines. The 1/4 inch body diameter and NPT thread make it compatible with the most common shop-air hose and manifold configurations. It is sold individually and is a practical stock item for service bays, maintenance shops, and trade vehicles carrying air tools.

Installation Notes

Depressurize and bleed the air line completely before removing any existing coupler or fitting. Apply thread sealant tape to the MNPT threads per standard shop practice before threading the coupler into the hose end or manifold. Hand-tighten first, then snug with an appropriate wrench — do not over-torque brass fittings. After installation, pressurize the system gradually and check for leaks at the thread joint before returning the air line to service.
