Ask A Question

Description & Features

Designed for grease, instrumentation, and most hydraulic systems, this straight hex adapter connects a 3/8-18 male NPTF thread to a 1/4-18 male NPTF thread, reducing between two pipe-threaded fittings in a single inline component. Constructed from steel, it provides reliable performance across a broad temperature range with a rated minimum working temperature of -65°F. Both ends feature dry-seal NPTF threading, which helps minimize the need for additional thread sealant. Manufactured by Danfoss Power Solutions under the Aeroquip line, this fitting carries catalog number C1BA73 and is classified under UNSPSC code 40183100.

The Steel Adapter, 3/8-18 Male NPT To 1/4-18 Male NPT, Straight is suited for industrial fluid systems where a step-down transition between standard pipe thread sizes is required.

Question by: Cody W on Feb 17, 2025, 7:25 AM
Got a 3/8 NPT female port that needs to connect to 1/4 NPT male fitting - will this work backwards or do I need something else?
Answer by: Customer Support on Feb 19, 2025, 6:22 AM
You'll need a different adapter for that setup. Both ends of this particular fitting are male NPT threads - one end is 3/8-18 male and the other is 1/4-18 male. Since you have a female port and need to connect to a male fitting, you'd want an adapter with at least one female end to accept your male fitting.
