Cylindrical 316 stainless steel pipe nipple with threaded ends

Legend Valve

Legend Valve 316-188 2-1/2" x 5" 316 Stainless Steel Nipple

SKU CH-M1KN-MXBCB

A 2-1/2" x 5" 316 stainless steel pipe nipple for corrosion-resistant plumbing connections

  • Corrosion-resistant 316 stainless steel withstands harsh environments
  • 5-inch length provides extended reach for piping connections
  • 2-1/2-inch diameter fits standard large-bore plumbing systems
  • New condition ensures clean, undamaged threads for reliable sealing
  • California Proposition 65 compliance disclosure included for safety awareness

Application & User

This Legend Valve 316-188 nipple is a 2-1/2" x 5" pipe connector designed for plumbing installations requiring corrosion-resistant fittings. It suits professional plumbers and maintenance crews joining stainless steel piping systems in commercial or industrial settings. The product is not intended for buyers needing different diameters, lengths, or threaded configurations. It also does not serve applications requiring plastic, brass, or carbon steel material compatibility.

Material Specification

The single specification that determines fit is the 316 stainless steel construction, which provides the corrosion resistance required for specific fluid-handling environments. This grade dictates chemical compatibility and longevity in the intended service. Selecting a different alloy would change the performance envelope entirely. The part carries a California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.

Thermal, Noise & Power

As a passive mechanical fitting, this nipple generates no operational noise, draws no power, and produces no heat of its own. Its thermal behaviour follows the temperature of the fluid and the surrounding piping system. Performance limits are defined by the pressure rating and temperature range of the connected schedule pipe, not by the fitting itself. Installation quality determines joint integrity under thermal cycling.

Questions about this item

What does the 316 grade mean once this nipple is installed in a piping system?

Grade 316 stainless steel contains molybdenum that resists chlorides and acids better than lower grades, so the nipple holds up in coastal, chemical or high-temperature service.

How does the NPT thread standard affect what this nipple can connect to?

The NPT taper threads seal when tightened, letting the nipple join any 2-1/2 inch NPT fitting without a gasket.

What clearance and tooling are needed to fit a 2-1/2 inch nipple that is 5 inches long?

You need a 2-1/2 inch pipe wrench and enough space to turn it, plus room for the 5 inch length between the two connected fittings.
