API 682 - Plan 74 Barrier Gas solution

Plan 74 sends an external buffer gas, typically nitrogen, between the inboard and outboard seals, and prevents leakage in case of seal failure. Our solution contains a coalescing filter to nearly eliminate process emissions and moisture.
Advantages of Plan 74s include:

  • lower installation and maintenance cost over liquid dual pressurized systems
  • leakage into process across the inboard seal is an inert gas
  • leakage of nitrogen past outboard seal is an inert gas

Our API Plan 74 panel assembly contains 100% Swagelok components so the quality shines through, and you can have peace of mind that our materials and assembly work are supported by our warranty.

Don’t risk unplanned downtime with your current setup. The transition is simple, and we can help customize.
