Sankey Keg Coupler – 6 Types Stainless Steel Beer Keg Tap Connector

A: The body is made of food-grade 304 stainless steel with a chrome-plated brass or stainless probe, ensuring corrosion resistance, durability, and safe contact with beer. Internal seals are made of FDA-approved rubber/EPDM.

Yes. The couplers feature standard connections — typically 5/8" thread for the beer-out line and 5/16" barb for the gas-in line — making them compatible with most home kegerators, jockey boxes, and commercial draft setups.

The coupler is rated for a working pressure of up to 70 PSI, with a built-in pressure relief valve (PRV) for safety. Normal serving pressure is 10–14 PSI depending on the beer style.

After each keg (or every 2 weeks for active use), disassemble the coupler and soak the parts in a beer-line cleaning solution (e.g., PBW or a caustic-free cleaner), rinse thoroughly with warm water, and lubricate the O-rings with food-grade keg lube before reassembly. Avoid bleach, which can damage seals and stainless steel.
