MP76 Series for API 682 Plan 76

The MP76 is a Primary Seal Condition Monitoring Unit that aligns with API 682 Piping Plan 76. This leakage collection system is for an unpressurized dual, dry running containment seal in noncondensing applications and uses a vent connection to direct vapor leaks from the inboard seal of a dual containment seal. The MP76 series may be used with a Plan 72 buffer gas and ensures very low (or even zero) process emissions from outboard containment seals.
