Pilotseal BDJ


PILOTSEAL Boiler Door Joint sheet material is constructed from a high-quality polymer, primarily for use as a boiler door joint. The high-temperature capability combined with the sealing resilience expected from an elastomeric material makes it ideal for steam service duty. Boiler door joints, gaskets on water heaters, air receivers, paper mill drying cylinders, and many other gasket services that use similar seals.
No grease, jointing compound or proprietary paste is needed to achieve an efficient seal, even on imperfect surfaces that may cause problems with other gaskets. After use, the gasket can be easily removed eliminating the need to scrape
