Alascop WP304LS Stainless Steel End Cap 4 Inch Schedule 40

Alascop WP304LS Stainless Steel End Cap, 4 in Schedule 40, is a butt-weld cap designed to seal the end of a 4-inch nominal stainless steel pipe in standard Schedule 40 runs. The cap is fabricated from 304L stainless steel and intended for butt-weld connections, enabling a permanent, weld-only joint without threaded or flanged interfaces. It is sized for 4 in nominal pipe size (NPS) and conforms to common stainless steel butt-weld fittings standards, including ASTM A403. This end cap provides a clean interior and a closed end for piping systems, making it suitable for terminating runs in industrial settings where 304L stainless steel is preferred for corrosion resistance and compatibility with sanitized or chemical-handling environments. When paired with a compatible 4-inch Schedule 40 stainless steel pipe, the WP304LS cap completes a secure butt-weld connection that matches standard Schedule 40 pipe thickness and promotes a continuous interior surface for ease of cleaning and fluid flow. Key specs: material 304L stainless steel; end connection butt-weld; ASTM A403.
