Usa Sealing ZUSA-TF-VAC-80 Clamp for Vacuum Fitting 2 in Tubing

SKU CH-SV3N-YFGY4

A stainless-steel clamp secures 2-inch vacuum tubing to ISO-K flanges and withstands 85 psi at 320 °F

  • Secure vacuum seal to 10-7 torr rating
  • Wing nut locking mechanism for tool-free tightening
  • Stainless steel construction withstands 320 °F maximum
  • GB4982-ISO-K standard ensures flange compatibility
  • Operates reliably from 4 °F to 320 °F

USA INDUSTRIALS Vacuum Clamp

The USA INDUSTRIALS ZUSA-TF-VAC-80 clamp secures 2 inch tubing in vacuum fitting assemblies. It is built for engineers and technicians who need a reliable seal on stainless steel tube lines rated for high vacuum service. The wing nut locking mechanism allows quick installation and removal during system maintenance. This component suits cleanroom, laboratory and industrial process environments.

Build Integration Requirements

The clamp matches a compatible flange outside diameter of 2 31/32 inches and conforms to the GB4982-ISO-K standard for flange compatibility. It requires mating flanges and tubing made from stainless steel to meet the specified vacuum rating. No lanyard is included, so the installer must provide any required tethering. The connection type is a standard clamp interface for vacuum fittings.

Sustained Load Behaviour

The assembly withstands a maximum operating pressure of 85 psi and a maximum operating temperature of 320 degrees F. It maintains a vacuum rating of 10-7 torr when measured at 72 degrees F. The minimum operating temperature is 4 degrees F, allowing use in chilled process lines. Stainless steel construction resists corrosion during prolonged exposure to process gases and thermal cycling.

Highlights

  • Secure vacuum seal to 10-7 torr rating
  • Wing nut locking mechanism for tool-free tightening
  • Stainless steel construction withstands 320 °F maximum
  • GB4982-ISO-K standard ensures flange compatibility
  • Operates reliably from 4 °F to 320 °F

Questions about this item

Will the 85 psi pressure limit be the first constraint I hit during continuous vacuum service?

The clamp is rated for 85 psi maximum operating pressure and a vacuum level of 10-7 torr at 72 degrees F, so the pressure ceiling is the primary limit during sustained use.

How much heat can the stainless steel body and wing nut handle in an all-day process?

It operates continuously between 4 degrees F and 320 degrees F, so the assembly tolerates high-temperature cycles without degrading the clamp or lock mechanism.

Which flange standard must my existing fittings match for this clamp to seal correctly?

The clamp conforms to GB4982-ISO-K and fits a flange outside diameter of 2 31/32 in, so your mating flanges must meet that same specification.
