Ask A Question

Description & Features

Designed for reducing connections between 1/2-14 Male NPT and 3/8-18 Female NPT threads, this Steel Adapter, 1/2-14 Male NPT To 3/8-18 Female NPT, 90 deg Elbow is part of the Eaton Aeroquip 2089 Series. The 90-degree elbow configuration allows for directional changes in tight installations where straight fittings are not practical. NPTF thread form on both ends provides a dry-seal connection that resists leakage without relying solely on thread compound.

With an A dimension of 1.47 inches and a B dimension of 1.02 inches, this steel adapter is suited for demanding industrial environments including marine and military systems, chemical processing, pulp and paper, food and beverage processing, and off-shore drilling applications. The catalog reference for this fitting is C1BB29.

Question by: Rex C on Jul 14, 2025, 6:02 AM
Been trying to track down a 1/2 male NPT to 3/8 female NPT elbow adapter for a while now, this the right part for that?
Answer by: Customer Support on Jul 15, 2025, 2:11 PM
Yeah, that's exactly what this one is. The male end is 1/2-14 NPT and the female end is 3/8-18 NPT, and it comes in at a 90 degree elbow configuration. Both threads are NPTF, so you get a pressure-tight mechanical seal without relying on sealant tape alone. It's made by Eaton Aeroquip under their 2089 Series, so it's a known quantity in the industrial fittings world.
Question by: Darryl R on Oct 28, 2025, 7:50 AM
Will this adapter work for connecting a 1/2" male NPT to a 3/8" female NPT at a 90-degree angle?
Answer by: Customer Support on Oct 29, 2025, 8:42 PM
That's exactly what this Eaton Aeroquip adapter is made for. It's a 90-degree elbow designed to connect a 1/2-14 male NPT to a 3/8-18 female NPT fitting.
