Bevel Seat Stainless Steel Sanitary Fittings are used on process equipment and piping to ensure rigidity. Bevel seat unions are made of a threaded bevel ferrule joined with a plain bevel ferrule. Both the threaded bevel ferrule and the plain bevel ferrule are available in either 304 or 316L alloy. The ferrules are joined by 304 hex-nuts. Gaskets are not required for positive shut-off of Bevel Seat Unions, but can be purchased on request. Our bevel seat fittings meet all 3A requirements. On most items, other finishes and configurations are available on request.
