Description & Features

Part of the Eaton Aeroquip 2216 Series, this Steel Adapter, 3/8-18 Female NPT To 1-1/16-12 Male SAE O-Ring Boss (Straight Thread O-Ring), Straight provides a reliable straight connection between NPT pipe threads and SAE O-Ring Boss ports. The male SAE ORB end uses a straight thread with an O-ring seal, eliminating leak paths common with tapered thread connections.

Constructed from steel, this adapter is well-suited for demanding service environments including marine and military, chemical processing, pulp and paper, food and beverage processing, and offshore drilling applications. The straight configuration with a 1.34-inch A dimension makes it a practical choice where direct port-to-port routing is required without angular offset.

Catalog reference C1HQ94 can be used to cross-reference this part within Eaton Aeroquip documentation.

Product Questions & Answers (1)

Question by: Glen S on Jan 7, 2026, 11:36 AM
trying to hook a 3/8-18 female NPT port up to an SAE ORB line, is this the right adapter?
Answer by: Customer Support on Jan 9, 2026, 6:14 AM
For that hookup, this part matches those thread ends: 3/8-18 female NPT on one side and 1-1/16-12 male SAE O-Ring Boss (straight thread O-ring) on the other, in a straight adapter body.
