Product Questions & Answers

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

Question by: Roy R on Oct 25, 2025, 6:24 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 thread is this cap, and is it the O-ring face seal style or something different?

Question by: Ralph G on Sep 1, 2025, 8:27 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.
