The EATON 2045-6-6S is a straight industrial pipe adapter designed to connect a 3/8-18 male NPT thread to a 3/8-18 female NPSM thread. This adapter is manufactured from steel and rated for a maximum working pressure of 4,000 psi, with a pressure rating of 2,500 psi per SAE standard 140130. It handles operating temperatures from -40 degrees F up to 250 degrees F, making it suitable for demanding hydraulic and fluid system applications. Plumbers, pipefitters, and hydraulic technicians install this adapter when converting or transitioning between NPT and NPSM thread forms in high-pressure line assemblies.
This adapter is suited for use in industrial hydraulic systems, fluid transfer lines, and high-pressure plumbing assemblies. Its straight configuration makes it a direct in-line fitting for tight routing situations. It is commonly used in both stationary and mobile hydraulic equipment where a thread-form transition between MNPT and FNPSM connections is required. The compact, single-piece steel construction keeps the installation profile low and minimizes potential leak points.
Designed as an OEM-style replacement or service fitting for industrial hydraulic and fluid systems requiring a 3/8-18 MNPT to FNPSM straight pipe adapter.
Installation should be performed by a licensed plumber, pipefitter, or qualified hydraulic technician. Depressurize and isolate the fluid system completely before removing or installing any fittings. Apply thread sealant appropriate for the fluid media and pressure rating; do not use sealants that are incompatible with the system fluid. Inspect threads on both the adapter and mating ports for damage before assembly.
