	Pool Gate Seals For maximum leaktightness and reliability, the gates are generally supplied with double Type 1 inflatable seals of fully molded construction (rather than extruded construction). Fabric reinforcing is also incorporated for additional structural integrity and better resistance to rupture and tear. When required, flexible "J" seals can be supplied in lieu of inflatables. The gates are of either hinged or liftout design. view animation
	Personnel Airlock and Escape Lock Door Seals Pawling manufactures inflatable seals, "O" ring gaskets and compression gaskets for personnel airlock doors and equipment hatches at nuclear plants throughout the world. The major features of these seals and gaskets are: Molded construction, rather than extruded, for close cross section tolerances. Inflatable seals are molded endless i.e. there are no after cure spliced joints that could be possible weak points. Inflatable seals have fabric reinforcing for maximum structural integrity.

Quality Assurance: All steps in engineering, manufacture, inspection and test are closely controlled by our nuclear quality assurance program based on ANSI N45.2 and 10CFR50 Appendix B. Our replacement seals and gaskets may be purchased through your airlock/equipment hatch supplier. view animation
	Airtight / Watertight Doors Pawling supplies seals for a wide range of special purpose doors from small man doors to giant truck or rail car access doors. We can assist you in new designs, or, if existing seals do not afford the desired degree of leaktightness, we can furnish inflatable seals for mounting to existing doors to provide a leaktight installation.
	Reactor Pressure Vessel Nozzle Plug Seal Assemblies Pawling furnishes for these plugs special resilient inflatable seals and/or flexible gaskets. Key features are: Radiation resistance Fabric reinforcing of the inflatables for maximum strength and durability Good resistance to compression set in the compression seals and flexible gaskets.
	PWR Steam Generator Nozzle Plug Seal Assemblies Pawling has considerable experience in various design concepts for these plugs. Typical arrangements include inflatable seals, independently valved for redundancy, with a noninflatable backup seal (lip seal or compression gasket). Since the aluminum plug has joints where sections are fastened together, an elastomeric diaphragm, vulcanized around its outer periphery to the inflatable seals, covers the plug and seals the joints on the "wet" side. We will assist you in the design of complete plug assemblies for new installations. For existing plugs, replacement seals and gaskets may be purchased through your original nozzle plug supplier.
