Frequently Asked Questions
Q: How do I read this fitting's size callout?
The sizes listed are nominal inch dimensions for each end of the fitting — the hose-barb or GHT end is sized to the hose it slides into, and the NPT end is sized to the threaded port it screws into.
Q: Will this fit standard NPT-threaded marine plumbing?
Yes — NPT is the standard tapered pipe thread used throughout marine plumbing, so this fitting threads directly into NPT-tapped ports, valves, and other adapters.
