Bonded Seals by PamarganWasher Specifications The Pamargan bonded seal is a rectangular section, metal washer, with a trapezoidal shaped ring of vulcanised rubber bonded to the inside. Both the washer and the material can be selected to suit a given application. The seal is for use in high pressure environments where copper washers are unsuitable. Improvements An improvement to the original concept is the self-centralising bonded seal - designed by Pamargan - that offers additional benefits. It is available in all popular BSP sizes and many other metric sizes. Bonded Seal Imperial Size Listing Ref | Alternative reference | A mm | B mm | C mm | D | E | Min.
