Vulcanised & Welded Bellows

Manufactured specifically for demanding applications where seams inherent to a sewn bellow are not acceptable. Similar to the standard Sewn Bellow, sections are cut separately and then joined to form the completed cover; the Sealed Sections are joined by vulcanizing rather than sewing, resulting in a seamless cover. This technique results in many advantages including a neater appearance, longer life in abrasive environments, and a complete seal to withstand moderate internal or external pressures.

Vulcanized Bellows

Why choose Vulcanised & Welded Bellows?

  • Individually joined pieces provide optimum extension.
  • When aesthetic appearance is a key factor.
  • When you require a leak tight seal.
  • Long Life.
  • Good Chemical Resistance.
  • Good Mechanical Strength.
