Key pre-sale checks: (1) confirm the customer needs a \u003cstrong\u003e1\/4\" NPT\u003c\/strong\u003e thread — not 3\/8\" NPT; (2) confirm they need a \u003cstrong\u003efemale\u003c\/strong\u003e NPT port (accepts a male NPT fitting), not a male NPT port; (3) confirm the panel thickness is within the fitting’s mounting range (check the product spec sheet for min\/max panel thickness). Use fuel-compatible thread sealant (PTFE tape or thread compound) on any male NPT fittings threaded into this fitting.
