METAL BELLOW SEALS

H609

  • Metal Bellows - High Temp.
  • Alloy 42 Low Expansion Holder
  • Imperial Sizes
  • Elastomer-Free

H609 is an edge-welded metal bellows mechanical seal designed to provide resistance to extremely high temperatures e.g. applications involving hot oil transfer. It features a narrow cross-section for better adaptability to suit traditionally narrower seal chambers.
