Resilient, single spring, rubber diaphragm seal with a Type 20 boot-mounted stationary as standard, to suit original common UK housing sizes. A widely utilised seal type highly suited to general duties, capable of long service life.

These seals are increasingly preferred with a narrow profile and a resilient elastomer mounted face for improved performance and these are available as Types N10 and N20.

Also available with ‘O’-Ring mounted stationaries, as Types 10H and 20H.
