Quick Coupler for Refrigeration Hoses

This brass quick coupler connects 1/4 inch male fittings to 1/2 inch Acme female threads. It is built for HVAC technicians who need a reliable quick-connect and disconnect point on refrigeration hoses. The tool-type design suits professional service work on automotive and stationary cooling systems.

Fits Standard Quick-Connect Hose Assemblies

The coupler threads directly onto existing hose ends without adapters, freeing up time during refrigerant recovery and charging. Its brass construction resists corrosion from common refrigerants and oils. No special tools are required beyond the wrenches already carried for hose work.

Holds Seal Under Continuous Pressure

The sealing faces maintain integrity during extended recovery or evacuation cycles rather than only during brief pressure checks. Brass threads resist galling when couplers are repeatedly tightened and released on the job site. The coupler is sold new and restricted from sale in certain states.

Questions about this item

Does the brass quick coupler restrict refrigerant flow after hours of continuous charging?

The brass body is built for repeated connect and disconnect cycles on refrigeration hoses and does not impose a flow restriction that worsens with sustained use.

Will the coupler get hot or vibrate when left on a running recovery unit all day?

The coupler has no moving parts or electrical components, so it generates no heat or noise of its own during extended operation.

What hose fittings must I already have to use this 1/4 inch male by 1/2 inch Acme female coupler?

You need a refrigeration hose with a 1/4 inch female quick-connect on one end and a 1/2 inch Acme male thread on the other to mate with both sides of this coupler.
