Product Questions & Answers

what's the tube OD on this cap, and is that 1-11/16-12 thread the male end or the female side?

Question by: Patty G on May 28, 2025, 7:01 PM

The tube OD on this cap is 1.25 inches. The 1-11/16-12 thread is the male O-ring face seal end, and the cap itself is female, meaning it threads over that male fitting to seal it off. So you've got a male ORS port on your line, and this cap screws onto it to close it up.

i’ve got a 1-11/16-12 ORFS port I need to deadhead for now. Is FF9863-20S the right cap for that?

Question by: Joyce B on Aug 10, 2025, 11:36 AM

For a temporary close-off on an O-Ring Face Seal connection, this part is an ORS cap assembly with a 1-11/16-12 male thread, so it matches that thread callout and style.

What size is the O-ring face seal on this cap? I'm trying to match it up to something I already got.

Question by: Rhonda B on Dec 29, 2025, 5:03 PM

This adapter cap has a 1-11/16-12 male O-ring face seal. That should help you find the right match.

what thread size is on this cap? need to make sure it'll fit a 1-11/16-12 port before I order

Question by: Chad A on Dec 5, 2025, 9:24 PM

The male fitting on this cap is 1-11/16-12, which is a standard O-Ring Face Seal thread size. It'll seat directly onto a matching female ORS port and create a clean, leak-resistant seal when torqued down properly. Just confirm your port matches that thread pitch and you're good to go.
