Custom Rubber Fabrications

For many years, Pawling has manufactured custom products for highly unique applications. These custom rubber fabrications can be supplied in a variety of elastomeric and reinforcing materials to suit many unique requirements.

	A low temperature silicone seal with integral heating cable to preserve the seal's integrity under very cold conditions (< 60°F).
	A unique profile manufactured with cover and liner of dissimilar properties to maximize its life in difficult environments.
	An inflatable seal with RFI-EMI shielding.
	A large multi-layer fabric reinforced expansion joint used to seal large gaps and withstand seismic movement.
	Inflatable pads for lifting or applying uniform clamping or bonding pressure.

Sealing Small Diameters

When the OD or ID of the surface to be sealed is too small for a standard Pneuma-Seal cross section, fully molded Type 22 inflatable bladders are employed (PR16376 and PR16436 below). This concept is generally used for seals less than 2" (~50mm) in diameter, but may be used for seals up to 6" (152.4 mm) or more in diameter. On request, Pawling can supply the complete unit which includes the machined housings.

Two-Piece Seals

When excessively high pressure differentials and/or harsh environmental conditions are present, 2-piece seals can be utilized. The solid elastomeric sealing pad isolates and protects the inflatable actuator tube.

Mechanical Interlocking Seal Ends

For installations where the inflatable seal must be wrapped around a shaft or other cylindrical surface, and cannot be installed over the end, mechanical interlocking male-female molded seal ends can be incorporated. (This option is only available in limited profiles. Please consult Pawling.)
