Air Pipe Unions
Unions join two sections of pipe while still allowing them to be taken apart later without cutting. That makes them a smart choice at points where you may need to service equipment, add a component, or reconfigure a run down the road, all while keeping the connection tight and leak-free.
These unions are part of our full range of air pipe and fittings, and they work hand in hand with our aluminum air pipe systems for flexible, serviceable layouts.
