Quick Coupler 1/4 QC x 1/8 FE NPT
The JB Industries QC-S4A is a brass quick coupler designed for HVAC service connections. It joins a 1/4 inch quick-connect fitting to a 1/8 inch female NPT thread on copper lines. The right-handed 180-degree orientation suits straight-line installations. Technicians use it to speed up refrigerant hose changes on site.
Check thread size and orientation before ordering
Verify that the existing port accepts a 1/8 inch female NPT connection. Confirm the system uses copper fittings compatible with this coupler design. Ensure the straight 180-degree profile fits the available clearance around the service valve. The coupler is restricted from sale in certain states so check local regulations.
Brass construction resists corrosion during
The metal body withstands pressure fluctuations encountered during refrigerant recovery and charging. Seals maintain integrity over many connect and disconnect operations without leaking. The straight flow path reduces restriction when the system runs under sustained load. Performance stays consistent across long service sessions.

Questions about this item
Does the package include the copper fittings or do I need to buy them separately?
The coupler is designed for use with copper fittings; the fittings themselves are not included and must be purchased separately.
Should I choose a different angle or thread size for my manifold setup?
This model is a right-handed 180-degree coupler with 1/4 QC by 1/8 inch female NPT threads; select it only when that exact orientation and thread combination matches your manifold ports.
How does the 180-degree right-hand angle affect hose routing on a live system?
The 180-degree right-hand bend points the hose straight back from the port, keeping the line tight against the manifold and reducing snag risk in tight engine bays.
