Midland Industries 28619P Hex Nipple 2in Mpt Polypropylene

Product Description

The MIDLAND INDUSTRIES 28619P is a polypropylene hex nipple designed for connecting two threaded pipe sections in low-pressure fluid handling systems. Both ends feature 2-inch male pipe threads (MPT) with a 2-11-1/2 thread specification, making this fitting suitable for joining same-size threaded lines. The black polypropylene construction provides corrosion resistance and lightweight handling in environments where metal fittings are not preferred. Rated at 125 psi, this nipple is appropriate for cold water, irrigation, chemical transfer, and other non-high-temperature piping applications. Plumbers and pipefitters install this type of fitting when extending or connecting plastic threaded pipe runs.

This hex nipple is used in residential and light commercial plumbing, irrigation systems, and industrial fluid transfer lines where plastic threaded fittings are specified. The hex body profile allows standard wrench engagement for secure installation without overtightening. It is suited for indoor and outdoor applications where polypropylene is compatible with the conveyed fluid. Always verify chemical compatibility of polypropylene with the specific fluid being handled before installation.

Key Features

• 2-inch MPT on both ends for same-size threaded pipe connections
• 2-11-1/2 thread specification for standard NPT compatibility
• Polypropylene construction for corrosion resistance and chemical durability
• Hex body profile allows wrench engagement for controlled tightening
• Rated to 125 psi for low-pressure fluid handling systems

Compatibility

Designed as an OEM-style replacement or standard fitting for 2-inch MPT threaded plastic pipe systems using polypropylene-compatible fittings.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or local plumbing codes. Shut off the water supply and depressurize the line before beginning work. Apply appropriate thread sealant tape or compound to the male threads before engaging the fitting. Do not overtighten polypropylene fittings, as excessive torque can crack the hex body.
