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

Answer by: Customer Support on Jun 3, 2025, 6:30 AM

it's a 1-7/16-12 male O-ring face seal fitting. That's a size 16 ORS cap from the Eaton Aeroquip FF9863 series, made to cap off male ORS ports when a line isn't in use or during storage and transport.

Question by: Harold P on Mar 24, 2025, 6:28 PM

trying to cap off a male ORFS port, is this the right kind of piece for that

Answer by: Customer Support on Mar 25, 2025, 7:48 PM

Made as an ORS cap assembly, it’s meant to cap a male O-ring face seal connection. The thread on this one is 1-7/16-12 male ORFS.
