Magnetic Seals

Magnetic seals are used when axial space is limited to <.500" and operating conditions and customer requirements are beyond elastomeric or polymer seal capabilities. Our magnetic seals have two components: the seal head assembly and the magnetic mating ring. These two components create a magnetic attraction, which eliminates the need for a spring and other items needed in face seal designs. This allows for our seals to be used in a variety of applications that have limited space requirements.
