Steel Adapter, 7/8-14 Male SAE O-Ring Boss (Straight Thread O-Ring) Socket Hex Plug

This adapter is made to fit a 7/8-14 male SAE O-ring boss, also known as a straight thread O-ring port.

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.

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.

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.

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.
