Quick Coupler 1/4 In Mx 5/16 In F
This brass quick coupler connects a 1/4 inch SAE male fitting to a 5/16 inch female fitting. It is built for HVAC professionals servicing refrigeration systems. The straight 0-degree angle allows direct inline installation. Working pressure is rated at 1000 psi for high-pressure refrigerant lines.
Check hose ends and system pressure
Verify that your existing hoses use quick connect/disconnect ends matching the 1/4 inch male and 5/16 inch female sizes. Confirm the system operating pressure does not exceed the 1000 psi rating. Ensure the straight configuration fits the available space between service ports.
Replaces worn or mismatched couplers
Swap out leaking, corroded or incorrectly sized couplers to restore a secure seal on refrigerant hoses. The upgrade is worth it when the current fitting cannot hold 1000 psi or when thread sizes differ from the 1/4 inch and 5/16 inch combination required.

Questions about this item
What comes with the A31656 quick coupler and do I need to buy hoses separately?
The box contains the brass quick coupler only; quick-connect refrigeration hoses must be purchased separately.
The listing shows a single connection size of 1/4 In. SAE male by 5/16 In. female — is that the only version available?
Yes, this model is offered only in the 1/4 In. SAE male x 5/16 In. female, 0-degree configuration.
What does the 1000 psi working pressure mean when the coupler is installed on a live system?
It indicates the maximum continuous pressure the brass fitting is rated to hold without leaking or deforming.
