HVAC Quick Coupler 180° Brass
The JB Industries QC-S5 is a straight-through brass coupler built for HVAC service work. It connects a 5/16 inch quick-connect fitting to a 1/4 inch SAE flare on copper tubing. Technicians use it to join refrigerant lines quickly during installation or maintenance. The 180-degree body keeps the flow path in line without sharp bends.
Brass Construction In-Line Flow
Solid brass resists corrosion from refrigerant oils and moisture encountered on job sites. The in-line 180-degree layout means the hose or pipe runs straight through the coupler without offset. This reduces stress on copper fittings during pressure checks and charging. No valve core or shut-off mechanism is present inside the body.
5/16 QC to 1/4 SAE Sizing
The single specification that decides fit is the connection: 5/16 inch quick-connect on one side and 1/4 inch SAE flare on the other. It only works with copper fittings made to those exact thread forms. Buyers who need a different flare size or a quick-connect diameter other than 5/16 inch cannot use this coupler.

Questions about this item
What does the 180-degree angle change on a 5/16 QC x 1/4 SAE coupler?
The 180-degree bend points the 1/4 SAE port straight back from the 5/16 quick-connect, letting you hook up in tight spots without kinking the hose.
What clearance does the 3-inch brass body need to swing clear?
The 3-inch length means you need roughly three inches of straight run behind the fitting so the coupler can rotate fully without hitting anything.
How do you seat the 5/16 quick-connect on copper without leaks?
Push the coupler onto the clean copper fitting until the sleeve clicks, then tug gently; skipping the click leaves the O-ring unseated and causes leaks.
