Winery Tank Door Gaskets
All of our tank door gaskets and inflatable seals are made in the USA by employees in the USA with ingredients from the USA.
Tank Door Gaskets
Our quality winery and brewery tank door gaskets come in over 140 different styles, sizes, and hardnesses. They can fit either belly-in or belly-out doors, oval tank doors or round tank doors.
We also make cut to length gaskets with over 25 different cross sections. These gaskets are extruded to the required length and then the ends are hot vulcanized together, to create a solid gasket. Hot vulcanizing the ends together creates a more durable gasket than gluing the ends together.
Our gaskets can be made to order for tank doors from a 6 inch full face tank door, up to 6 foot diameter (and larger) tank door.
