Fasten in seals

Inflatable seals retained without mechanical foot structures, designed for versatile groove installations.

Simple configuration. Multiple retention options.

Footless seals do not have foot-like structures for mechanical retention. They are retained inside grooves using adhesive bonding, ribs, or tight-fit installation. This is one of the simplest and most commonly used inflatable seal configurations.

TYPES (FASTEN-IN SEALS)

Round (RD)

Round footless seals are among the most widely used inflatable seal profiles. They provide uniform expansion and are suitable for general sealing applications with simple groove designs.

Dovetail (D)

Dovetail footless seals are designed to improve retention inside the groove. The dovetail geometry helps limit seal movement during inflation and operation.

Dovetail (D)

Fabric-reinforced dovetail seals are used where higher internal pressures or demanding conditions are present. The internal fabric reinforcement improves strength and limits deformation during inflation.

Oblong (O)

Fabric-reinforced oblong seals are selected for applications requiring added durability. The reinforced structure enhances seal life in challenging operating environments.
