Midland Industries 55141 Pvc Pipe Nipple 1-1/2 in Sch 80

Product Description

The MIDLAND INDUSTRIES 55141 is a Schedule 80 PVC close nipple designed for threaded pipe assemblies in plumbing and industrial piping systems. It measures 2 inches in length with a 1-1/2 inch diameter and carries male pipe thread (MPT) connections on both ends sized at 1-1/2 inches. Manufactured from dark gray PVC, it is rated for 234 psi working pressure and conforms to ASTM F1498 dimension standards. The heavier wall thickness of Schedule 80 construction makes this nipple suitable for higher-pressure applications where standard Schedule 40 fittings are not adequate. Plumbers and pipefitters install this type of fitting in chemical distribution lines, irrigation systems, and industrial process piping.

This nipple is used in residential and commercial plumbing installations where corrosion resistance and chemical compatibility are required. Schedule 80 PVC nipples are common in irrigation manifolds, pool and spa equipment connections, chemical feed lines, and industrial fluid handling systems. The dark gray color is the standard industry indicator for Schedule 80 PVC pressure fittings, making it easy to distinguish from lighter-duty Schedule 40 components during installation and inspection.

Compatibility

Designed as an OEM-style replacement and standard-fit component for Schedule 80 PVC threaded piping systems using 1-1/2 inch MPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with PVC threaded piping per applicable IPC or local plumbing code requirements. Apply a compatible PTFE thread sealant tape or thread compound rated for PVC before threading the nipple into fittings. Hand-tighten first, then use strap wrenches rather than metal pipe wrenches to avoid cracking the PVC body. Verify system pressure does not exceed the rated 234 psi working pressure for this fitting.
