Pipe Plug 


The Preferred Engineering Pipe Plug is an aluminum and Stainless Steel assembly that uses Buna-N elastomer seals. The design uses passive mechanical compression to achieve a seal.  


  • No bolts to torque for seal compression. 

  • Eliminated blind flanges 

  • Reduced dose by reduced installation time 

  • Seals inside your present opening without modification 

  • Adjustable Toggle Clamps to accommodate nozzle variations to change seal compression. 

  • Optional redundant retention studs
