A-Type Coupler

Please note that most A-type kegs are too tall to fit in the Series 4 or Series X without a "KL00390 - Low Profile Elbow Bend" and an EPDM 5/8" Washer on the coupler's liquid out side (sold separately).

**How to Install the Gas Duck Bill Valve:**

1. Remove the black EPDM washer inside one of the Duotight push-in fittings that you will use for gas.
2. Insert the duck bill valve, which serves as both a washer and a non-return check piece.

Using the non-return check pieces for gas or liquid is optional.
