The EATON 3300X8X6 is a straight brass pipe coupling designed for industrial fluid and pneumatic systems requiring a reliable threaded connection. It features a 1/2 inch by 3/8 inch female-to-female FNPTF thread configuration, making it well suited for reducing connections in pressurized lines. Rated to 1,200 psi maximum working pressure and capable of handling temperatures from -65 degrees F to 250 degrees F, this coupling is built for demanding service environments. Plumbers, pipefitters, and industrial maintenance technicians install this fitting in hydraulic, pneumatic, and fluid distribution systems.
This coupling is used in residential, commercial, and light industrial piping applications where a straight, reducing female-threaded connection is needed. The FNPTF thread standard ensures a pressure-tight seal when mated with compatible male NPT fittings. Typical installation scenarios include compressor lines, hydraulic manifolds, and general-purpose fluid transfer piping where a 1/2 inch to 3/8 inch female thread reduction is required.
Designed as an OEM-style replacement fitting for industrial and commercial piping systems using FNPTF threaded connections in 1/2 inch by 3/8 inch female configurations.
Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable codes such as the IPC or IFGC. Depressurize and isolate the line completely before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten; use the hex flats for wrench engagement to avoid distorting the fitting body.
