4" x 5" 316 Stainless Steel Nipple
This Legend Valve 316-228 nipple provides a 4-inch by 5-inch connection point for plumbing assemblies. It is built from 316 stainless steel for corrosion resistance in water supply or fluid transfer lines. The component suits installers needing a straight, threaded pipe section of this specific length and material grade. It is not for systems requiring a different diameter, length, or material specification.
Sustained corrosion resistance
The 316 stainless steel construction resists pitting and degradation during continuous exposure to water and common chemical treatments. This alloy maintains structural integrity under constant pressure and flow conditions typical in plumbing networks. The material choice supports long service intervals without the scaling or rust associated with lower-grade metals. The product carries a California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.
Threaded installation
Standard pipe threads allow the nipple to screw directly into compatible fittings using common wrenches and thread sealant. Correct alignment prevents cross-threading, which is the most frequent cause of leaks at the joint. Over-tightening can distort the threads or crack the mating fitting, requiring replacement. No special tools or adhesives beyond standard pipe tape or compound are needed for a secure seal.

Questions about this item
Does the 316 stainless nipple generate noise, heat or draw power when installed in a continuous-flow system?
It is a passive fitting with no moving parts, so it produces no noise, no heat and consumes no power during all-day operation.
What existing pipework must I already have to connect this 4" x 5" nipple?
You need a matching 4-inch female NPT thread on each adjoining pipe or fitting to screw the nipple into place.
Will this 316 stainless nipple corrode when joined to older brass or galvanised fittings in my RV plumbing?
Direct contact with dissimilar metals can accelerate galvanic corrosion, so dielectric unions or isolation bushings are recommended when mixing with brass or galvanised components.
