When the temperature is hot or space is limited, Technetics Group’s circumferential seals are the answer. Their compact construction simplifies installation, and the circumferential seal assemblies are easily disassembled and repaired on site.

About Technetics Group Circumferential Seals

Circumferential seals are designed to minimize the leakage of fluid or gases by sealing directly against the shaft (segmented seal) or by using a closely controlled clearance between the floating circumferential ring and a rotating shaft (bushing seal). Since no elastomers are used, circumferential seals can be used in wide range of temperatures.
