Nipples 330511205 Pipe Nipple 3/8 in Npt Sch 80 Steel 5-1/2 in

Product Description

The NIPPLES 330511205 is a Schedule 80 steel pipe nipple with male NPT threads on both ends, designed for medium-pressure piping systems in commercial and industrial applications. It carries a nominal pipe size of 3/8 inch and measures 5.5 inches in overall length. The welded steel construction provides thicker walls than Schedule 40, making it suitable for applications where higher pressure ratings are required. Licensed plumbers and pipefitters install this type of nipple as a short run connector between threaded fittings, valves, and other piping components in process, mechanical, and utility systems.

This nipple is used in medium-pressure piping installations across a range of residential mechanical, commercial plumbing, and light industrial system types. Its Schedule 80 wall thickness is appropriate for systems operating at elevated pressures where Schedule 40 wall thickness is insufficient. The male NPT threads on both ends allow for direct connection into female-threaded fittings, valves, couplings, and tees without adapters. The 3/8 inch nominal pipe size is a common diameter in compressed air, steam, gas, and water distribution lines.

Key Features

• Schedule 80 wall thickness for medium-pressure service, thicker than Schedule 40 and thinner than Schedule 160
• Male NPT x Male NPT thread configuration on both ends for standard threaded system connections
• Welded steel construction for durability in mechanical and plumbing applications
• 3/8 inch nominal pipe size fits standard 3/8 in NPT fittings and valves
• 5.5 inch overall length suitable for close-quarter or extended nipple runs

Compatibility

Designed for use with Schedule 80 medium-pressure threaded fittings and valves using 3/8 inch female NPT connections in commercial and industrial piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements for the intended service. Shut off and depressurize the system completely before removing or installing any threaded components. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly, and tighten to a snug fit using pipe wrenches without over-torquing the connection. Inspect threads for damage before installation.
