Question by: Melvin B on Jul 4, 2025, 7:12 AM
Got a -04 diagnostic port on a test manifold and need to cap it off between uses. This the right part for that, or am I barking up the wrong tree?
Answer by: Customer Support on Jul 5, 2025, 1:47 PM
That's what this cap is for. The FD90-1040-04 is a -04 coupling size dust cap built for diagnostic quick disconnect ports following the SAE J1502 interchange standard. It pushes on one-handed thanks to the automatic sleeve, and the flush face valving keeps fluid loss to a minimum when you pull it off for testing. Buna-N seals and zinc-plated steel body means it holds up in regular shop or field conditions without much fuss.
