Midland Industries 55161 Sch 80 Pvc Pipe Nipple 2 in Mpt

Product Description

The MIDLAND INDUSTRIES 55161 is a Schedule 80 PVC close nipple used to connect two female-threaded fittings in pressurized piping systems. Machined to a 2-inch male pipe thread (MPT) on both ends with an overall length of 2.5 inches and an outside diameter of 2 inches, this nipple is rated for 200 psi service. The dark gray PVC construction resists corrosion, chemical exposure, and moisture, making it a reliable choice for potable water, irrigation, and industrial fluid systems. Threads conform to ASTM F1498 dimensional standards. Licensed plumbers and pipefitters are the typical installers for this type of fitting.

This nipple is suited for residential and light commercial plumbing applications where Schedule 80 pressure ratings are required. Common installations include pump discharge assemblies, filter manifolds, chemical injection systems, and pool or spa plumbing where plastic fittings are specified over metal to prevent corrosion. The 2-11.5 thread form ensures consistent engagement with standard NPT female fittings throughout the system.

Key Features

• Schedule 80 PVC rated to 200 psi for higher-pressure plumbing applications
• 2 in MPT on both ends for direct male-to-female threaded connections
• ASTM F1498 thread dimensional standard for consistent fit with standard NPT fittings
• Dark gray PVC resists corrosion, chemicals, and UV degradation better than standard white PVC
• Compact 2.5-inch length suits tight installations and close-coupled connections

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 2-inch NPT female-threaded Schedule 80 PVC fittings, valves, and pipe couplings in pressurized plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Depressurize and drain the system completely before removing or installing any threaded fittings. Apply a compatible thread sealant or PTFE tape to the male threads before assembly; do not use petroleum-based compounds on PVC threads. Hand-tighten first, then advance with a strap wrench - avoid pipe wrenches directly on PVC to prevent cracking.
