Description
The Wayland Industries 4″ Sanitary Dome Cap is a professional-grade component for sealing off process lines or vessels in high-purity systems. Constructed from ultra-high purity T316L Stainless Steel, it offers superior corrosion resistance compared to T304, making it suitable for high-acid environments and harsh chemicals. This dome cap features a polished 7W finish (32Ra) and a butt-weld end, ensuring a permanent, high-strength seal with no internal crevices where bacteria can harbor.
Technician’s Note: Use only high-quality T316L compatible filler rods and orbital welding for the most consistent, sanitary results. Ensure the 4-inch pipe end is cut perfectly square and deburred before welding. The domed design provides superior structural strength under pressure compared to flat end-caps. This fitting meets 3-A sanitary standards for food-contact surfaces.
