0.500" OD 16ga Butt-Weld End Cap - (16W) - Polished OD/ID - 316L Stainless

Butt-Weld End Cap (16W) – 316L Stainless Stainless Steel

PNW Sanitary Butt-Weld End Caps (16W) provide a permanent, sanitary solution for sealing the ends of stainless steel process lines. Manufactured from 316L stainless steel and polished to a 32Ra sanitary finish on both the ID and OD, these dome-style end caps offer exceptional corrosion resistance and a smooth, crevice-free termination point ideal for hygienic piping systems in food, beverage, dairy, brewery, cosmetic, nutraceutical, and pharmaceutical applications.

Designed to be welded directly to sanitary tubing or weld fittings, the 16W dome cap creates a strong, rigid, and leak-resistant closure suitable for unused line ends, standpipes, instrumentation tees, and high-purity system terminations. Standard sanitary wall thicknesses are matched to tube OD to ensure proper fitment and long-term durability in welded stainless systems.
