QUALITY & EXPERTISE FOR YOUR SEALING NEEDS DESCRIPTION The BECA 114 is a BS ring composed of a metal ring with a rectangular cross- section, to the inside of which a rubber ring with a trapezoidal cross-section has been bonded and vulcanised. ADVANTAGES Economic solution Precise positioning of the ring Can be disassembled and reused Reliable sealing at both high and low pressures Reduced assembly time APPLICATIONS Sealing under the screw heads and bolts General mechanics Motors Pipe fittings Valves MATERIALS Rubber NBR 70 and 90 Shore A FKM 70 and 90 Shore A EPDM 70 and 90 Shore A Metal insert Cadmium-plated steel Stainless steel Other grades of materials are available.
