SKU CH-Q2S1-8FC5S

A 3-inch stainless steel pipe nipple for plumbing connections, made from corrosion-resistant 316 alloy

  • Corrosion-resistant 316 stainless steel construction

Product Identity

The Legend Valve 316-204 is a 3" x 3" pipe nipple manufactured from 316 stainless steel for plumbing installations. It provides a corrosion-resistant connection between two female-threaded components in piping systems.

Suitability

This fitting suits installers joining two female NPT threads in a straight line where 316 alloy resistance is required. It is not for systems needing a reducing size, an elbow change of direction, or a different material grade such as brass or carbon steel.

Critical Specification

The defining attribute is the 316 stainless steel construction which determines chemical compatibility and corrosion performance. California Proposition 65 warnings apply because the product contains a chemical known to cause cancer and birth defects or other reproductive harm.

Highlights

  • Corrosion-resistant 316 stainless steel construction
  • 3-inch by 3-inch dimensions for standard plumbing connections
  • Legend Valve brand quality for reliable performance

Questions about this item

What thread size does the 3" x 3" 316 stainless steel nipple require for a leak-free fit?

The nipple has 3-inch NPT threads on both ends, so matching 3-inch NPT fittings or pipe are needed for a proper seal.

Which step is most often missed when installing a 316 stainless steel nipple into an existing line?

Applying PTFE tape or pipe-thread sealant in the direction of the threads before tightening prevents leaks that dry assembly causes.

How often should the 316 stainless nipple be inspected or replaced in a corrosive fluid system?

Inspect annually for pitting or thread deformation; replace immediately if wall thinning or cracking appears, especially under Proposition 65-listed chemical exposure.
