Product Questions & Answers (5)

Question by: Warren M on Sep 17, 2025, 9:25 PM
Will this here fitting work with standard SAE O-ring ports?
Answer by: Customer Support on Sep 19, 2025, 6:12 AM
This adapter is made to fit a 7/8-14 male SAE O-ring boss, also known as a straight thread O-ring port.
Question by: Lynn D on Jun 25, 2025, 11:34 AM
Got a port that's calling for a 7/8-14 SAE O-Ring Boss plug, will this one do the job, and does it come with the seal or do I need to track that down separate?
Answer by: Customer Support on Jun 27, 2025, 9:02 AM
The seal is included. Part number 22617-10 comes with this adapter, so you won't need to source an O-ring separately before installation. The male end is 7/8-14 thread, matching standard SAE O-Ring Boss ports, and the hex socket drive makes it straightforward to torque down in tighter spots where a wrench can't get a good swing.
Question by: Neal F on Apr 27, 2025, 6:32 PM
got a port that’s 7/8-14 SAE ORB, is this the right plug for it?
Answer by: Customer Support on Apr 29, 2025, 5:13 PM
For a 7/8-14 SAE O-Ring Boss (straight thread O-ring) port, this part matches that thread and end type and is meant to plug it using an O-ring seal. The seal part listed for it is 22617-10.
Question by: Bobby H on Jan 29, 2026, 11:16 AM
what industries is this plug actually rated for? trying to figure out if it'll hold up in a chemical processing setup before i order a handful of 'em
Answer by: Customer Support on Jan 31, 2026, 6:08 AM
Chemical processing is one of the listed application areas for this fitting, along with marine, military, pulp and paper, food and beverage processing, and offshore drilling. That covers a pretty wide range of demanding environments, so it holds up well where fluid compatibility and sealing integrity matter. The male SAE O-ring boss thread design gives you a reliable metal-to-metal seat backed by the O-ring, which is part of why it gets used across those tougher industries.
Question by: Wade W on Jun 21, 2025, 8:36 PM

Answer by: Customer Support on Jun 22, 2025, 9:00 PM
This adapter is suitable for a range of applications including marine/military, chemical processing, pulp and paper industries, and food and beverage processing, as well as off-shore drilling.
