Description
BOSS Sealing encapsulated seals was mainly designed to solve the sealing problem under extremely chemical and temperature conditions wherever the chemical resistance of normal elastomer o-rings is not sufficient.
Encapsulated seals has both of the good properties of FEP or PFA and the rubber elastomer.It has good chemical resistance and very flexible as well,this unique combinations makes a quite good sealing effect.
