Frequently Asked Questions

How do I know which fitting thread I need?

Identify the thread size and gender on both parts you are joining (common sizes are 1/4", 3/8", and 1/2" NPT or M22 on consumer machines). Match male to female and size to size, or use an adapter to bridge two different threads.

Should I use stainless steel or brass fittings?

Brass is the economical choice for everyday cold-water work. Stainless steel holds up better against chemicals, hot water, and abrasive water, making it worth the upgrade for high-hour and soft wash operations.

Why is my fitting leaking?

Most leaks come from worn O-rings, missing thread sealant, or a mismatched thread. Replace the O-ring, wrap male NPT threads with PTFE tape, and confirm the threads actually match before reassembling.
