Technical information


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.

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.
