Eaton 3326X8 Close Nipple 1/2 Inch Mnptf 1200 Psi

Product Description

The EATON 3326X8 is a close nipple fitting designed for industrial pipe assemblies requiring a short, threaded male-to-male connection. Machined with a 1/2-inch MNPTF (Male National Pipe Taper Fuel) thread on both ends, this nipple measures 1-1/8 inches in overall length and carries a maximum working pressure rating of 1,200 psi. It handles a temperature range from -65 degrees F to 250 degrees F, making it suitable for demanding fluid and gas piping applications. Plumbers, pipefitters, and industrial maintenance technicians install this fitting where minimal spacing between two female-threaded components is required.

The EATON 3326X8 close nipple is suited for use in industrial process piping, hydraulic lines, compressed air systems, and fuel-supply lines where a compact male-threaded connector is needed. Its MNPTF thread standard ensures a pressure-tight seal when properly assembled with compatible female fittings. The fitting is appropriate for both residential and light commercial applications where high-pressure pipe connections must be made in tight quarters.

Installation Notes

Installation of pipe nipples is typically performed by licensed plumbers or pipefitters in accordance with the International Plumbing Code (IPC) or applicable local codes. Shut off and depressurize the system completely before removing or installing any threaded fittings. Use an appropriate thread sealant or PTFE tape rated for the service fluid and pressure before threading the nipple into the mating fittings. Do not overtighten tapered pipe threads, as this can cause fitting damage or cracking.
