Stainless Steel Conical Union 304
AISI 304 welded conical unions for demountable joints on stainless pipelines where inspection, cleaning, or maintenance access is required without cutting the line. Cone-seat geometry suits food, beverage, water, and light process duty when paired with matching faces and seals. Quoted and sold per piece.

Applications & Selection Guide
Stainless steel conical unions in AISI 304 (DIN-style welded union with conical seat) — a three-part demountable joint: two weld ends and a threaded coupling nut sealing metal-to-metal on the cone.
Conical unions let you open a welded stainless line without cutting: around pumps, valves, instruments, filters, and any component needing periodic removal. The metal-to-metal cone seals without a gasket, tolerating steam and CIP temperatures. Select the size matching your tube OD from the table above; 316 versions are available for chloride service.
Quoted and sold per piece (complete union set). Include size, quantity, and delivery country in your quote request.
