Product Identity

The Legend Valve 316-173 is a 2-inch by 9-inch pipe nipple manufactured from 316 stainless steel. It serves as a straight connector for extending or joining pipe runs in plumbing systems requiring high corrosion resistance.

Application Fit

This fitting suits installers working with 316 stainless piping where chemical resistance and durability are priorities. It is not intended for systems requiring a different alloy, alternative thread standard, or dimensions other than the stated 2-inch diameter and 9-inch length.

Decisive Specification

The 316 stainless steel construction determines suitability for environments where standard carbon steel or lower-grade alloys would corrode. Verify that the piping material and service conditions match this alloy before installation.

Questions about this item

What pipe diameter and length does the 316-173 nipple require for a proper fit?

The 316-173 nipple is a 2-inch diameter by 9-inch length 316 stainless steel pipe nipple, so it fits any 2-inch NPT female threaded opening with enough clearance for the 9-inch overall length.

How do you install the 316-173 nipple and what threading step is often missed?

Apply PTFE tape or pipe thread sealant to the male NPT threads on both ends of the 316-173 nipple, then tighten into the mating 2-inch female fittings; the step often missed is wrapping the tape in the direction of the threads so it does not unravel during tightening.

When will the 316 stainless steel nipple need replacement in a corrosive system?

316 stainless steel resists most chemicals, but in systems with high chloride levels or stagnant acidic water, inspect the 316-173 nipple annually for pitting or crevice corrosion and replace it if wall loss exceeds acceptable limits for the pressure rating.
