Comments about 1" FIP Brass Union:

There was a small nick in the mating surface of the union causing a leak. I had to work it out with some emery cloth. I eventually got it, but it was not fun.
Otherwise, the product was a-okay.

Difficult to get a water tight seal

By Ed

from St Paul, MN

Verified Buyer

Comments about 3/4" FIP Brass Union:

I had to apply an unusually high amount of torque to get this union to seal. The water pressure inside was only 13 lbs so it should not have taken so much torque. There might have been a bur on it but I did not want to drain the entire heating system again to remove it and look for the defect.

    Q:

    Does this union require teflon tape to seal properly?

      A:

      No, Unions seal metal to metal at the face. The faces are ground to produce a seal, without pipe dope. Teflon tape may help you tighten the connecting nut by reducing the friction at the threads, but it has no effect on the sealing surfaces.

      A:

      No, wouldn't help at all, might hurt.  Recently I researched how to seal unions, and the pros were saying "nothing, dry".  A couple said ok to use pipe dope on the mating surfaces.  Might help to put something on the threads to lubricate & make it easier to tighten, but that won't affect sealing at all, except you might get it tighter.
      Be VERY CAREFUL not to get solder on the mating surfaces!  I can attest that's almost impossible to fix, you'd have to replace the whole fitting.  I went through hell over that mistake. 
      Lots of opinions to be found on this subject!!!

      I used pipe thread compound to seal the threads.

      A:

      This is an age old question - do you need an additional seal on brass
      threads? Brass is relatively soft, so you can get away with no seal. I
      always use tape on brass, because I don't want to go back and re-do it - if
      it doesn't seal up.
      I think you may be asking about the retaining not needing tape?? No. This
      isn't the part of the union that see's any fluid - it simply tightens the
      inside joint. If you look inside the union, you will see the joint that
      fits together and the nut just holds it tightly in place.
      Hope this helps.

      A:

      According to the manufacturer, teflon tape will prevent it from sealing. The seal is metal-to-metal between the number 1 tail and the number 2 tail. The fluid should never get to the nut. If it does, the sealing face has been compromised somehow.

    Q:

    What Specification is the Union joint made to? Is there a commercial specification for the joint?
    Asked on 5/23/2012 by Malachi from Milwaukee, WI

    • CUSTOMER CARE

      A:

      According to the manufacturer, the ansi standard for threaded brass is ANSI B16.15. The standard covers material and the number of threads, and general length considerations for the manufacture of fittings including these union fittings.That said there is no specification within the standard for the actual union ground joint. This is also true for copper fittings unions. Each manufacturer is allowed to manufacture this portion as they determine best. This is why you cannot take two different companies unions apart and put them together interchanging the component tailpieces and nuts. Some will be fine thread union joints and some will be coarse thread joints.
