Product Questions & Answers (5)

Question by: Danny K on Jan 15, 2026, 11:14 AM

Will this adapter work for hydraulic applications in a marine environment?

Answer by: Customer Support on Jan 16, 2026, 4:03 PM

Given its application in marine and military settings, it should hold up just fine in a marine hydraulic system.

Question by: Lance H on Feb 25, 2026, 1:51 PM

got a hose end with a 13/16-16 ORFS male, will this adapter screw right onto that and then into a 7/8-14 ORB port?

Answer by: Customer Support on Feb 27, 2026, 6:13 AM

The ends are a 13/16-16 male SAE O-Ring Face Seal (ORFS) on one side and a 7/8-14 male SAE O-Ring Boss (straight thread O-ring) on the other. It is a straight steel adapter meant to connect those two thread types and sizes.

Question by: Earl K on Jul 27, 2025, 7:00 PM

got a 13/16-16 ORS port on one end and a 7/8-14 ORB port on the other, will this adapter bridge those two without needing anything extra besides the o-rings?

Answer by: Customer Support on Jul 29, 2025, 9:14 AM

Both connection types use o-ring sealing, so no thread sealant is needed on either end. The adapter comes with seal parts 22617-10 and FF9446-14 included, so you should have what you need right out of the box to make that connection between a 13/16-16 male ORS fitting and a 7/8-14 male SAE O-Ring Boss port.

Question by: Patty B on Nov 19, 2025, 1:29 PM

Will this adapter let me hook up a SAE O-ring face seal to a SAE O-ring boss?

Answer by: Customer Support on Nov 21, 2025, 6:50 AM

This straight adapter is specifically made to connect a 13/16-16 Male SAE O-Ring Face Seal to a 7/8-14 Male SAE O-Ring Boss, also known as a Straight Thread O-Ring.

Question by: Denise C on Nov 16, 2025, 6:34 AM

what industries is this adapter actually used in? trying to figure out if it's right for our setup

Answer by: Customer Support on Nov 17, 2025, 9:27 PM

Food and beverage processing, chemical processing, pulp and paper, marine and military applications, and offshore drilling are all listed uses for this adapter. The O-ring face seal on one end and the O-ring boss on the other make it a solid fit for systems where leak-free connections matter and fluid compatibility has to hold up across demanding environments.
