UPOR O-RING
The covered precision O-Ring type UPOR was developed to meet specific requirements of the chemical industry.
Due to its high resistance to chemicals and pressure, it can also be applied to many other industrial fields.
It consists of an elastomer core for the pretension of the joint to be sealed and a seamless cover of FEP which provides resistance to aggressive substances.
