Question by: Roy R on Oct 25, 2025, 6:24 AM

got a line that’s 3/4 tube OD, is this cap gonna match up with that ORS setup?

Answer by: Customer Support on Oct 26, 2025, 8:53 AM

The key callouts are 3/4 inch tube O.D. and an O-Ring Face Seal (ORS) end. This cap assembly is labeled as an ORS accessory with a 0.75 tube O.D., so it lines up with a 3/4 ORS connection.

What size tube does this cap fit?

Answer by: Customer Support on Mar 25, 2026, 7:42 AM

This cap is designed to work with a 0.75 inch OD tube.

what size thread is this cap, and is it the O-ring face seal style or something different?

Answer by: Customer Support on Sep 3, 2025, 7:44 AM

The thread is 1-3/16-12, and yes, it uses an O-ring face seal (ORS) configuration. That sealing style seats the O-ring flat against the face of the mating port rather than relying on thread engagement alone, which gives you a much more reliable leak-free connection on hydraulic lines.

i just need to cap off a 1-3/16-12 male ORFS port, is FF9863-12S the right kind of piece?

Answer by: Customer Support on Jan 5, 2026, 1:17 PM

For closing off a male O-Ring Face Seal connection with 1-3/16-12 threads, FF9863-12S is an ORS cap assembly made for that job.
