Blue Max Boiler Gaskets

Rubber gaskets can't withstand that kind of pressure and heat.

BlueMax® are formable. OBROUND and OVAL SIZES ARE INTERCHANGEABLE. This can be a real lifesaver on the job.

Allstate Gasket provides a complete range of Blue Max® boiler gaskets sizes in OVAL and OBROUND shapes.
From 3" x 2" to 22" x 12". Contact Allstate for quantity discounting, custom gaskets or any sizes or shape gaskets.

Make sure to see our boiler supply page - tapes, ropes, spiral wound gaskets, boiler kits for all types of boilers:


  • Easy to install
  • Easy to remove - Teflon!
  • Chemical resistance - inert with most chemicals
  • For rough surfaces - conformal
  • Extra-long shelf life
The long-time industry-standard for maximum enhanced flange seal. Blue Max® boiler gaskets are made from a special formula glass/elastomer-impregnated tacky cloth. The gaskets have their sizes clearly marked to aid installation. These super-strong gaskets resist splitting due to over-tightening flange surfaces.

Blue-Max® boiler gaskets will give you all of the advantages of an asbestos gasket without the health risks. Blue-Max® gaskets are manufactured from a proprietary tacky cloth of glass synthetic fibers and brass wire, and impregnated with a blue elastomer compound.

Zero Leakage Under Pressure - Tests by major boiler manufacturers confirm that Blue-Max® gaskets seal- with zero leakage-on steam to 450 psi and on cold-water hydro tests up to 1500 psi and Blue-Max® withstands working temperatures up to 500 degrees Fahrenheit. Rubber gaskets can't withstand that kind of pressure and heat
