CT Gasket & Polymer Co., Inc.
T-Seals Design Principle. A T-seal consists of a ring of elastomeric material that has a T-shaped cross section, and two bands of relatively rigid material that belong on either side of the elastomer ring. The ring acts as the sealing component of the unit, and the two rigid bands act as backup rings that prevent extrusion of the elastomer ring into the extrusion gap of the gland. As a bonus, the backup rings in a T-seal serve an additional purpose: they firmly hold the sealing component to the floor...
