Stop chemical corrosion from destroying your industrial pumps and causing leaks throughout your process flow with Pump Pelseal® Viton™ Caulk

Use Pump Pelseal® Viton™ caulk to seal pump connections to hoses and junction fittings where chemicals are flowing. Our caulk will provide back-up Viton™ protection in and around your pumps where leaks often occur.

Fill Gaps and Plug Leaks

Use liquid Viton™ caulk to seal and fill gaps, pinholes, and plug leaks in pump connections created by long-term exposure to corrosive materials.


Viton™ Caulks - Pelseal® 2078 / Pelseal® 2690

We offer our caulks with different liquid viscosities to cover the entire range of applications. Pelseal® 2078 can flow and penetrate into gaps. Pelseal® 2690 can seal on top of surfaces where corrosion occurs. The 2078 and 2690 are solvent based caulks with zero VOC and have a 12 month shelf life. They are both packaged in standard sized (11oz./325ml) cartridges and dispensed with a standard caulk gun. Each cartridge is re-sealed with a screw-in cap, to ensure maximum use and no waste.
