2-1/2" 304 Stainless Steel Cap

The Legend Valve 404-129 is a 2-1/2 inch FNPT cap made from 304 stainless steel. It is designed for industrial plumbing systems that require corrosion-resistant pipe termination. The component suits maintenance engineers and pipefitters working on process lines or utility services.

304 Stainless Construction and FNPT Threads

The 304 stainless steel body resists oxidation and chemical attack in aggressive fluid environments. Female National Pipe Taper threads allow direct installation onto male-threaded pipe or fittings without additional adapters. The material choice supports long service life in water, oil, and many chemical media.

Replaces Carbon Steel or Plastic Caps

This cap upgrades from carbon steel fittings that rust in humid or corrosive atmospheres. It also replaces plastic caps that degrade under UV exposure or high temperature. The jump is worth it when system integrity demands metal-to-metal sealing and material compatibility with 304 stainless pipework.

Questions about this item

What thread standard does the 2-1/2" SS304 cap use and what does it seal against?

The cap uses FNPT (Female National Pipe Taper) threads to seal male NPT pipe ends in plumbing systems.

What pipe size and material grade does this cap fit?

It fits a 2-1/2 inch nominal pipe size and is made from 304 stainless steel for corrosion resistance.

How is the cap installed and what common step is missed?

Thread the cap onto the male pipe end by hand, then tighten with a wrench; the step often missed is applying PTFE tape or pipe dope to the male threads before assembly.
