Midland Industries 55168 Pvc Pipe Nipple 2in Mpt Sch 80

Product Description

The MIDLAND INDUSTRIES 55168 is a Schedule 80 PVC pipe nipple rated for demanding pressure applications in plumbing and industrial piping systems. Measuring 6 inches in length with a 2-inch diameter, it features male pipe thread (MPT) connections on both ends with a 2-11-1/2 thread form per ASTM F1498. Constructed from dark gray PVC, this nipple carries a 200 psi pressure rating, making it suitable for systems that exceed the limits of standard Schedule 40 fittings. Licensed plumbers and pipefitters install this type of fitting in potable water, irrigation, chemical handling, and general industrial piping layouts.

This nipple is intended for use in Schedule 80 PVC piping systems where threaded connections are required. The 2-inch MPT configuration fits standard Schedule 80 female-threaded fittings, couplings, valves, and other threaded components. Typical applications include commercial and industrial plumbing runs, pump discharge assemblies, and chemical distribution lines where PVC is an approved material. Its dark gray color is the standard identifier for Schedule 80 PVC, distinguishing it from lighter-duty Schedule 40 components in the field.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes governing PVC threaded fittings. Depressurize and drain the line completely before removing or installing any threaded nipple. Apply a PTFE tape or thread sealant rated for PVC and the intended service fluid - do not use petroleum-based compounds that can degrade PVC. Hand-tighten first, then use a strap wrench to avoid cracking the fitting from overtightening.
