Boiler Kits & Supplies

We provide boiler gasket replacement kits for the fireside and waterside of Superior, Cleaver-Brooks, Smith, Ajax boilers and many other popular manufacturers. JBSC uses high-temperature materials such as woven tacky cloth, fiberglass rope, and compressed non-asbestos compounds. We also provide other high-temp gasket materials such as fiberglass rope, vermiculite coated cloths as well as silica fiber materials which are capable of handling 2000°F. See our high-temperature sealants page.


What comes in our boiler kits? 


Everything you need comes in one package - you get:

  • Tadpole Head Gaskets
  • Burner Drawer Gaskets
  • Burner Housing-to Head-Gaskets
  • Housing To Inner Door
  • Dry Oven Door
  • Front & Rear Baffles
  • Fasteners & Rivets
  • Easy maintenance with quality parts!


Our replacement / equivalent gaskets, tapes, ropes and materials can often be more economical than OEM parts. After all, they're 'iron makers' and often buy their 'soft parts' from us — and so can you!  


NOTICE: Our fireside and waterside kits fit Cleaver Brooks® boilers and are comparable replacement gasket kits. They are not manufactured by Cleaver Brooks®. We are not affiliated with Cleaver Brooks® in any way.
