Facing stronger regulatory and environmental concerns, plant managers are always looking for better technologies and better products to enhance plant operations. But while plant engineers and maintenance supervisors tend to concentrate on the major plant systems, they might overlook important subassemblies, where improved products can still have an impact on plant performance. One such subassembly where a failure can have a substantial impact on performance isthe gasket, notably a manway gasket.

Manway gasket failures can lead to dangerous leaks, untimely equipment shutdowns and significantsafety risks. Gaskets are absolutely crucial to the containmentand integrity of your tank, manhole,manway, etc.
When faced with such gasket problems, facility managers often look to outside experts for solutions. At National Rubber, we specialize in providing high quality custom manway gaskets fora variety of applications to be used in the food, dairy, beverage and pharmaceutical industries.

Manway gaskets are also used to seal tanks and manholes in the pulp and paper industry, in water treatment plants, in dry bulk haulers, steel and stainless steel processing tanks and vessels, in ethanol storage tanks, and in many other industries. Our manway gaskets provide a positive seal against rough or uneven surfaces, seal with a very low stress, and fit tight against the manway.

As a leader in gasket manufacture, NationalRubber’s expertise allows us to deliver a complete sealing solution that boosts product performance. We can custom manufacture your manway gaskets out of any number of elastomeric compounds including Silicone, EPDM, Buna, and all FDA materials, depending upon the customer’s specific applications. Our team of engineers can work from a technical drawing or sample, even a sketch of your specific gasket need.  Since we offer no minimum order quantity, we will manufacture one-of specials.
