EXTERNAL SEALS

H10T / H10R

  • Externally Mounted
  • PTFE Bellows, Compact
  • Multi-Spring Pusher
  • Imperial & Metric Sizes
  • Suits Chemicals & Corrosives

H10T & H10R are mechanical seals designed to be mounted externally, such that no metal parts are in contact with the process fluid. This makes it ideal for use with highly acidic or chemically corrosive media.

 

The bellows is extended to allow a two-piece split clamp to tighten and drive the rotary.

 

The seal is based on the "10T & 10R" designs, where H10T PTFE face is non-replaceable, and H10R seal face is replaceable in hard materials.
