Fugitive Emissions Monitoring Inspection Ports

With the need to monitor emissions at insulated flange type connections for pipelines, valves, and equipment; APF offers an inspection port that helps monitor for fugitive emissions, 33°F to 500°F, on these high capital control connections.

Fugitive emission inspection port carries APF's technology as a most insulation effective, maximum inspection area, and most reliable sealing mechanism on the market.

RED FM inspection port has extended hours of safe production operations for on-surface applications across a variety of industries such as petrochemical, refining, food processing, and medical. 


Sealing and Insulation Mechanism

  • Outer seal 1, silicone under flange primary holding and sealant to jacketing
  • Outer seal 2, red silicone rubber plug for weather-tight barrier
  • Foam spacer maintains thermal efficiency

Red FEM Inspection Port

  • For insulated flange type pipe connections and valves.
  • Attaches to pipe jacketing; silicone under flange and red silicone plug are barriers for fugitive emissions.
  • Foam spacer maintains thermal efficiency.
  • Process temperature range 33°F to 500°F
  • Large silicone seal area under flange eliminates for jacketing cutout errors during installation, provides long-term water & fugitive emissions proof seal, and largest holding power in industry.
