Sealing ring
Reinforced rubber sealing ring for the flanged joints of rubber-lined pipes and fittings. It keeps the joint tight and protects the flange face from abrasive and chemical wear.
Product information
The ring is made by hot vulcanisation of a rubber compound in a press mould. A steel reinforcing ring inside keeps its shape and stops it from being squeezed out when the flanges are tightened. The profiled face, with a raised annular bead and sealing grooves, compresses evenly and seals the joint reliably.
