Ask A Question

Description & Features

Part of the Eaton Aeroquip 2083 Series, this Steel Adapter, 1-11-1/2 Male NPT To 1-11-1/2 Male NPT, Straight is designed for same-size pipe thread connections in hydraulic, instrumentation, and grease system lines. The straight configuration maintains a compact inline profile, making it well-suited for installations where directional changes are not required.

Constructed from steel with NPTF external pipe threads on both ends, the adapter provides a reliable, pressure-resistant seal appropriate for most hydraulic system pressures. The 1-11-1/2 NPT thread size on each port ensures compatibility with standard 1-inch pipe fittings across a wide range of industrial equipment.

With an overall length of 2.34 inches, this adapter fits cleanly into tight plumbing envelopes without adding unnecessary bulk. It carries catalog number C1BA65 and is a direct fit for applications requiring a male-to-male NPT nipple connection in the Eaton Aeroquip fitting family.

Question by: Kent G on Dec 26, 2025, 2:23 PM
got two ports that are both 1-11-1/2 male npt, is this basically just a straight nipple to join them?
Answer by: Customer Support on Dec 28, 2025, 6:38 AM
Function-wise, yes. It is a straight adapter with NPTF external pipe threads on both ends, so it connects two female NPT-style ports of the same thread size in a straight run.
