ISO-K Double Clamps (aluminum)

These single and double clamps are used (in conjunction with a centering ring with fitted o-ring) for mating ISO flanges. The ISO flange (also called Large ISO) is used for HV chamber ports and is available in two distinct styles; ISO-K which uses clamp fasteners and ISO-F which uses nut and bolt fasteners.

ISO Clamps Feature:

  • Single clamp used for mating ISO-F and ISO-K style flanges together
  • Double clamp used for mating ISO-K flanges only
  • Available in aluminum or cold steel (double clamps only)

NOTE: Clamps can NOT be used to connect two ISO-F flanges together. Mating ISO-F flanges require the use of a bolt kit (for tapped flanges) or bolt set (for clearance flanges).
