got a tight spot on a wet line setup. how wide is this female quick disconnect?

Compact is the main win here. The body width is listed at 0.88 inches, so it fits better than a lot of larger couplers when you do not have much room to work with.
Question by: Hank J on Mar 6, 2026, 7:10 PM
Push-to-connect sounds real handy, but does this thing need any kind of wrench or adapter to get it seated proper on a 1/8 inch NPT port?
Answer by: Customer Support on Mar 8, 2026, 5:14 PM
No tools required for the quick-connect side. The push-to-connect end locks in with a ball lock mechanism, so you just push it in and it seats. The other end is a standard 1/8 inch NPT female thread, so that side does thread onto your port the normal way. Just make sure your NPT fitting is clean and in good shape before you run it.
