Midland Industries 40086 Brass Nipple 3/4 X 4 Inch

Product Description

The MIDLAND INDUSTRIES 40086 is a brass pipe nipple sized at 3/4 inch nominal diameter by 4 inches in length. Pipe nipples are short threaded fittings used to connect two female-threaded fittings, valves, or ports in a piping assembly. Brass construction provides corrosion resistance and reliable sealing in a wide range of fluid and gas service applications. This fitting is a standard component installed by licensed plumbers, pipefitters, HVAC technicians, and gas service professionals in both new construction and maintenance work.

This nipple suits residential and light commercial installations where a short close-connected run is needed between threaded components. Common applications include water supply lines, compressed air systems, gas distribution piping, and hydronic heating circuits. The 3/4 inch size is one of the most widely used thread sizes in trade plumbing and HVAC piping assemblies, making this nipple a frequent go-to for connecting valves, regulators, gauges, and unions.

Key Features

• Brass construction offers corrosion resistance suitable for water, gas, and air service
• 3/4 inch nominal pipe size fits standard NPT-threaded fittings and valves
• 4 inch length provides a short extension between two threaded connection points
• Threaded both ends for direct inline assembly without additional adapters

Compatibility

Designed as a standard replacement or new-installation nipple for 3/4 inch NPT-threaded piping systems in plumbing, HVAC, and gas service applications.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or HVAC technicians following applicable local plumbing and mechanical codes. Shut off and depressurize the supply line before disassembling or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to the male threads before assembly and tighten to hand-tight plus the additional turns specified by the fitting manufacturer or applicable code. Do not over-torque brass fittings, as the material is softer than steel and susceptible to thread damage.
