Bevel Seat 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 can meet all 3A/DIN/RJT/SMS/IDF requirements.
