Industries & Applications

Transportation Seals and Gaskets

Railcar Door Inflatable Seals

Seals in these demanding environments must resist smoke generation, flame propagation, and toxic fume build up to ensure passenger safety. rubber seals made with low smoke silicone are used in conjunction with sliding doors on modern passenger railroad cars. Compression seals for windows and hatches have also been designed and manufactured using this new material.

Firetruck Cab Seal

Rubber seals can be configured in an U-shape or rectangular configurations and mounted across the head and down the jambs of the service compartment opening of fire apparatus tilt cabs to form a weathertight seal between the service compartment and the cab during normal operation. When maintenance is required, the seals allow the cab to tilt forward.

Medical Silicone Seals

Sterilizer Door Seals

Rubber seals in durable fabric reinforced silicone or EPDM rubber profiles are ideal for:

Sealing vertical lift doors on floor mounted sterilizers
Sliding doors on table top models
Large sliding doors on walk-in batch processing gas sterilizers.
Rectangular high pressure profiles are frequently chosen for autoclave doors to minimize particle trapping pockets.

Inflatable Seals for Airtight Doors

Airtight doors in virology laboratories, animal rooms and decontamination areas are tightly sealed with inflatable silicone seals installed around the periphery of the door to expand radially outward. This design facilitates frequent access since there is no requirement to actuate multiple dogs, and there is no raised sill to obstruct personnel and equipment traffic.
