Plastic & Composite Unions

Composite push-to-connect unions for air and fluid lines: straight unions with 14 stocked part numbers, DOT bulkhead unions, metric bulkhead unions and other union styles. A push-to-connect union joins two tubes of the same outside diameter without tools; bulkhead versions pass through a panel and lock with a nut. Cut the tube square before pushing it in.

Each listing groups the stocked part numbers for one style. Choose size and thread on the product page.
