As a premier gasket supplier, we take pride in manufacturing quality gasket products that deliver the premium fluid sealing performance your business demands. Available in full face, ring, and custom designed gasket styles in a variety of rubber elastomers, including FDA grade, high-temperature, and other hard-to-find gasket materials.
The Function of a Gasket is to create and maintain a static seal between two stationary, imperfect surfaces of a mechanical system, designed to contain a wide variety of liquids or gases. The gasket must be able to maintain this seal under all the operating conditions of the system including extremes of temperature and pressure. The performance of the gasket is affected by a number of factors. All of these factors must be taken into consideration when selecting a gasket.
UIP has the technology to automate just about any shape required for your application. Nonmetallic materials are available in widths up to 60 inches and sheet lengths of up to 50 feet depending on the product. For oversized gaskets, UIP has the capability of creating custom segmented gaskets for ease of handling and installation.
In order to ensure a successful seal many factors must be considered. The gasket material must be resilient and rugged enough to overcome any irregularities in the mating surfaces; resist extrusion and creep; and prevent blowouts under various operating conditions. Material thickness is also important when choosing a non-metallic gasket. The thinnest material that a flange application will allow should be considered however, the material should be thick enough to compensate for any surface irregularities or flange parallelism. Thinner gaskets can handle an increased level of bolt load and will reduce the amount of bolt stress that is lost due to relaxation. Additionally, thinner material reduces the gasket area which limits the amount exposed to attack from internal pressure and/or an aggressive application.
UIP suggests contacting one of our knowledgeable team members to select the correct material for your application. There are a number of gasketing materials available and new materials emerge often. Material specifications are also available in our literature and on our website to assist in proper material selection.
Many different materials are used and specific material call-outs are crucial for this industry. Gaskets require certificates of conformance, including batch numbers and cure dates with full traceability.
Nitrile and Viton™ (FKM), are commonly used materials because of their oil and fuel resistance. EPDM is commonly used for door seals and graphite/non-asbestos materials can be used in the combustion areas of an engine. Silicone is also used for high temperature applications.
Spiral wound, metal graphite and PTFE gaskets provide superior performance for highly corrosive and high temperature applications.
Cork, Neoprene, EPDM, and Nitrile materials can be used for sealing and ventilating electrical enclosures, circuit board support pads, mounting, switchgear and transformer components.
Silicone is used frequently as it is stable at high temperatures and also inhibits bacterial growth. For steam or other high pressure applications, non asbestos and/or graphite material may also be used. Other materials include FDA approved elastomers including EPDM and PTFE which offers chemical and UV resistance, and other white food grade rubbers.
Oil & Gas
High temperature and high pressure environments require special materials including spiral wound, ring type and non-asbestos materials.
Silicone and PTFE are the most commonly used materials for drug processing and conveyor belting. These materials provide a clean environment and low bacterial growth.
Shaft seals, valve seals and packings are made from Neoprene and EPDM. Nitrile, Viton™ (FKM), PTFE, and non-asbestos materials can also be used for more corrosive applications.
EPDM, Nitrile, non-asbestos, and Viton™ (FKM) are commonly used for manway gaskets to seal against fuel, oil and water.
NSF / ANSI 61 Certified gasket material is the preferred choice in the potable water industry. Other materials used include Red Rubber (SBR) and compressed non-asbestos for waste water services.
