Masterbuilt, Master Forge gasket mod

Masterbuilt / Master Forge propane or electric Smokehouse Gasket (improves smoker function/efficiency)

Fits all Master Forge or Master built coal, electric or propane smokers.  Includes enough material for both double or single door, including XL and model Masterbuilt 40" model 2051311GS30D.

Temp Range
Special Instructions:

This dense gasket is made with your choice of DuPont™ Nomex® fibers or Wool.  The gasket measures 1" wide and 1/8" thick.  It installs easily to create an airtight seal which results in better heat retention than your grill/smoker than factory.   Creates a much more stable and consistant cooking environment with better pellet efficiency.  This is a big upgrade over no gasket at all. 

Note: Wool is grey. Nomex ® (pictured) is white. 

For Masterbuilt / Master Forge mods: 

Sealed up tight, no smoke coming from the doors!

Installation directions: 

  • Best when installed on the door side.
  • Carefully, remove old gasket with putty knife.  (if applicable)
  • Clean surface with rubbing alcohol or food safe degreaser
  • Lightly sand surface to remove stubborn grease or old gasket
  • Remove paper backing from your new self-adhesive gasket.  Press to install, do not stretch.
