Question by: Chad H on Aug 1, 2025, 1:53 PM
both ends on this fitting are the same size or is one bigger than the other?
Answer by: Customer Support on Aug 3, 2025, 12:45 PM
Both ends are SAE 37 degree flare male connections, and both measure 0.4375 inches. So you're working with a same-size union on each end, not a reducer. If you need to step up or down between two different tube sizes, this particular adapter wouldn't be the right pick.

trying to replace an old union adapter, is this 2041-4-6S a male JIC to male JIC deal?
Answer by: Customer Support on Oct 19, 2025, 4:55 PM
For a quick ID, it is a 2041 Series union adapter with SAE 37 degree flare on both ends, and both ends are male. It is essentially an SAE 37 male to SAE 37 male union.
