Controlled Compression Gaskets

Controlled Compression Gaskets

Controlling The Compressive Load to Provide the Ultimate Surface I.D.

SPS Controlled Compression Gasket (CCG) maintains constant and controlled compression. The CCG gasket seal will not compromise the purity of the sanitary sterile process system.

A failed gasket; not a compression controlled gasket.

Over-tightening causes gasket Intrusion Into the piping I.D, which can result in tearing and sticking causing system contamination. Controlled Compression Gaskets act as a positive mechanical stop making "over- tightening" virtually Impossible.

A Superior Gasket

The Controlled Compression Gasket cannot be over-tightened!

The CCG is composed of the elastomer of your choice with a ring of ultem vulcanized inside the gasket from the ring O.D. to the locating ring. This non-compressible polymer controls clamp compression to exactly the correct amount, allowing the properly positioned gasket to make a perfect surface I.D. seal with the ferrules. No intrusion of the gasket in the product flow is possible.

The Controlled Compression Gasket literally transforms the tri-clamp connection into a perfect I.D. connection. Because the ultem ring acts as a positive mechanical compression stop when clamping, the clamp will not loosen due to gasket creep, aging or T cycles. This is true for any standard or high pressure clamp regardless if the clamp is secured with a wing nut, standard nuts or Torque-Rite.

Perfect...Every Time

Because there is no unsupported gasket intruding into the product flow, gasket service life is greatly extended. With this minimum surface contact area exposed, particulates, TOCs and other extractabtes are dramatically reduced.

Meeting the Stringent Standards For Purity

  • U.S. Pharmacopoeia Class VI-XXI Certification
  • Cytotoxicity Criteria
  • Title 21 CFR 177.2600
  • USDA and 3-A Sanitary Standards
  • Current Good Manufacturing Practices (CGMP)
  • ASME-BPE Standards
  • Animal Derived Ingredient Free
  • Compression of the gasket sealing surface is more than adequate to compensate for imperfections in ferrule faces. The ultem ring is ductile enough to allow for piping misalignment.
  • The ultem ring is color coded to indicate the elastomer type. Ring can be a sanitary Type I standard style or tabbed. Tabbed ring provides permanent record of batch and lot number as well as date of manufacture for tracking. The tabbed ring allows customer to eliminate human contact with the gasket surface and an area to record date of installation on the reverse side of the tab.
  • Ultem is a FDA compliant, USP Class VI approved, non compressible polymer. Maximum operating temperature rating is 450°F. Controlled Compression Gaskets can be autoclaved and depending on the elastomer selection can withstand up to 100 steam cycles.
