Eaton 3326X12 Close Nipple 3/4 Inch Mnptf 1200 Psi

Product Description

The EATON 3326X12 is a close nipple fitting designed for industrial pipe systems requiring a threaded male-to-male connection with minimal spacing between fittings. It features a 3/4 inch MNPTF (male national pipe taper fuel) thread on both ends and carries a maximum working pressure rating of 1,200 psi. The overall length is 1-3/8 inches, making it suitable for tight-clearance installations where a standard nipple would be too long. This fitting is installed by licensed plumbers and industrial pipefitters working on fluid or gas distribution systems.

This close nipple is used in residential and industrial piping applications where two female-threaded fittings must be joined with little or no gap. It is suited for hydraulic lines, compressed air systems, fuel delivery lines, and general fluid transport piping. The MNPTF thread standard provides a pressure-tight seal appropriate for high-pressure service up to 1,200 psi and temperature ranges from -65 degrees F to 250 degrees F.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC and IFGC code requirements. Depressurize and isolate the line before removing or installing any threaded fittings. Apply an appropriate thread sealant or tape rated for the fluid media and pressure to ensure a leak-free joint. Do not overtighten; inspect the connection for leaks after returning the system to service.
