Bulkhead Unions

Bulkhead Unions are optimally designed to directly thread through your equipment housing to connect internal tubing to the outside. Each union has unique 3/8-24 external threads and comes complete with a stainless steel nut and lock washer to hold it in place. It requires a 3/8” hole to mount. The recommended torque limit for these unions is 15 in.– lbs (1.7 N·m).
