Compression with SST Gasket Protector

Compression couplings with a stainless steel gasket protector inside are used on vacuum systems to prevent wearing holes in the gasket due to being drawn into the joint and into the line.


IAC Gasket Protectors provide positive gasket protection against abrasion or corrosion with no adverse effect on Coupling capabilities. They prevent gasket wear which occurs when pipe or tubing ends do not butt completely. This gap is often unavoidable and always undetectable. In vacuum systems, gaskets without Protectors can be drawn into the line enough to cause excessive wear and eventual system leaks. This may result in undesirable contamination of the materials being handled. IAC Couplings with Gasket Protectors fully eliminate these costly hazards to the effective and economical operation of vacuum conveying systems.

  • Are factory assembled – no loose parts.
  • Automatically compensate for field installation variations causing exposure of gaskets – prevent pinched gaskets at butt connections.
  • Gasket Protectors are of Type 304 stainless steel with interlocking teeth – excellent for protection against abrasion and corrosion.
