Aro/ingersoll-rand 104104-C02 Inline Check Valve 1/4 in Fnpt

Product Description

The ARO/INGERSOLL-RAND 104104-C02 is an inline check valve designed to allow one-directional fluid or air flow while preventing backflow in pneumatic and fluid-handling systems. Built with female NPT (FNPT) connections on both ends, this 1/4 inch pipe-size valve integrates directly into threaded line installations without adapters. It is rated for a maximum working pressure of 200 psi and handles temperatures from -18 degrees F up to 200 degrees F, making it suitable for a wide range of compressed air, hydraulic, and general fluid systems. Plumbers, pipefitters, and industrial maintenance techs are the typical installers.

This check valve is suited for residential and light commercial pneumatic systems, air compressor lines, fluid transfer plumbing, and general-purpose inline installations where backflow prevention is required. The 1/4 inch FNPT x FNPT configuration makes it a common choice for connecting directly to threaded ports on compressors, tools, manifolds, and control equipment. Its compact size and straightforward thread-in installation fit tight plumbing runs where space is limited.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Shut off and depressurize the line completely before removing or installing any inline valve. Apply thread sealant tape or pipe dope to the male threads of the mating fittings in accordance with applicable plumbing codes such as the IPC. Do not overtighten threaded connections, as this can crack valve bodies or distort sealing surfaces.
