We know seals - and the needs of our customers

In sealing technology, Angst+Pfister has focused primarily on industries that place high demands on seals - be it for long service lives, low coefficients of friction or very specific resistance to aggressive medias or to very high or low temperatures.

Many industries now require corresponding country-specific approvals, whether for the pharmaceutical and medical technology industries, the drinking water industry, the food and beverage industry or in the oil and gas industry. Very often, approvals are required which are valid and accepted in several countries and sometimes valid for only a single material - Angst+Pfister has here the right solution for you.

In addition to plastics such as PTFE or PEEK, elastomers play a particularly important role in sealing technology - from NBR, EPDM, VMQ, FKM to FFKM. Of course, we also carry materials such as NR, SBR or fiber composites in our product range.
