Customer Reviews for STZ 1 in. Black Iron Union

It worked.

Good quality and easy to use. Simplifies complicated pipe connections. Worked well for me.

Good quality with no issues. Threads were cut nicely and it came with a thin coating of machine oil on it.

This Union worked well and didn't need super tightening to get it sealed.

I shredded the threads on TWO of these! After purchasing an American made 1-1/2 union; I could see why....threads are entirely too shallow! AVOID USING THIS SIZE UNION FROM DEPOT. All other sizes I used (3/4, 1/2) were ok; but the 1-1/2 is flawed in design. I didn't think I was strong enough to break a union like this; but I was WRONG!
