Parker MP11099-1 Brass Long Nipple 1/4 Inch Mnptf

Product Description

The PARKER MP11099-1 is a brass long nipple fitting with a 1/4 inch male MNPTF thread, designed for use in industrial pipe systems requiring reliable threaded connections. This fitting carries a maximum working pressure of 1000 psi and handles temperatures from -65 degrees F to 250 degrees F, making it suitable for a wide range of fluid and gas transfer applications. The overall length is 1-1/2 inches. It is manufactured to SAE J530 and SAE J531 standards, ensuring dimensional accuracy and thread quality. Plumbers, pipefitters, and industrial maintenance technicians install this type of fitting as part of compressed air, hydraulic, or fluid distribution assemblies.

This long nipple is suited for residential, commercial, and light industrial piping systems where a short threaded extension or close connection between two female-threaded ports is needed. Typical applications include instrument connections, compressor fittings, manifold assemblies, and hydraulic lines. The MNPTF thread form provides a pressure-tight seal without requiring additional sealant in many installations, though thread sealant tape or compound is commonly applied per job specifications. Sold in a package quantity of 2.

Installation Notes

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 before removing or installing any threaded fitting. Apply thread sealant tape or compound to the male threads as required by system specifications and local code. Avoid over-tightening, which can crack brass fittings or damage mating threads.
