Smith-Cooper 1/8" Bronze Union

This Smith-Cooper union connects two 1/8" pipe sections in a straight line. The brass-nickel body carries a 125 pressure-class rating. It suits plumbing technicians and maintenance crews who need a removable joint for water or air lines. The part is supplied new from the manufacturer.

Check thread type and pressure class

Verify that both mating ports use the same 1/8" thread standard before ordering. Confirm the system working pressure does not exceed the 125 class rating of this fitting. Ensure the bronze-nickel material is compatible with the fluid or gas in your circuit. The manufacturer lists the item as first available in 2022.

Suits low-pressure 1/8" plumbing repairs

Installers joining two 1/8" pipes at a serviceable connection will find this union appropriate. Buyers who need a larger bore, a higher pressure class or a different alloy should look at something else. Those requiring welded or permanent joints will not use a union. Orders of 75 or more qualify for free shipping from the factory.
