- 180-degree angle enables tight-space access
- 3-inch length provides extended reach
- 3/8" Female SAE to 1/4" connection fits copper fittings
- No-depressor design simplifies refrigerant line coupling
- New JB Industries build ensures professional-grade reliability
Quick Coupler 180 Degree 3 in L
The JB Industries QC-S64 is a brass quick coupler built for HVAC service work. Its 180-degree body and 3-inch length give technicians clearance in tight service ports while maintaining a secure seal during refrigerant charging or recovery.
Replaces straight couplers in confined spaces
Swapping a straight coupler for this 180-degree model removes the need to bend hoses sharply at the manifold. The jump is worth it whenever the service port sits flush against a panel or coil and a straight fitting would kink the line or leak under pressure.
Suits technicians working on copper fitting systems
The 3/8-inch QC by 1/4-inch SAE thread matches common manifold and hose combinations used with copper fittings. Buyers who need a built-in valve depressor or a different thread combination should look at other models.

Questions about this item
What thread sizes do the 3/8 in female SAE and 1/4 SAE connections require for mounting?
The coupler uses a 3/8 in female SAE thread on one end and a 1/4 SAE thread on the other, so matching flare fittings are needed for each side.
How do I install the 180 degree quick coupler without damaging the copper fittings?
Thread each end onto the corresponding SAE flare fitting by hand, then tighten with a wrench; the common mistake is over-torquing the 3/8 x 1/4 connection which can crack the copper.
When should the internal seal on the no-depressor quick coupler be replaced?
Replace the seal if refrigerant leaks appear at the coupling point or if the quick-connect action becomes stiff, indicating seal wear from repeated cycles.
