Gaskets |
| Neoprene GasketsChloroprene (Neoprene) Moderately resistant to petroleum products. Good Ozone and weather resistance. Good compression set. Excellent for sealing refrigeration fluids such as Freon®. Temperature range -65o F to +250o F. Neoprene Gasket material comes in four primary forms; closed cell (wet suit material), open cell, diaphragm, and homogeneous. Each of these three types have styles, colors and density variations that make them unique gasket materials. Neoprene Gasket Material - Homogeneous Style 0725 - 60 Duro Neoprene blend provides moderate resistance to oil and ozone. For use in bumpers, pads, and sealing in general gasket and flange applications. Minimum tensile strength - 800 PSI. Durometer 60±5. Temperature range: - Style 0725S - 40 Duro Neoprene blend provides moderate resistance to oil and ozone. For use in bumpers, pads, and sealing in general gasket and flange applications. Style 0725H - 70 Duro Neoprene blend provides moderate resistance to oil and ozone. For use in bumpers, pads, and sealing in general gasket and flange applications. Style 0734 - 70 Duro Cloth Finish - Good resistance to Sunlight, and outdoor weathering. Performs well in contact with many oils and chemicals. Cloth Finish. Durometer 70 +/-5. Tensile strength 1000 PSI. Elongation 200%. Neoprene Gasket Material - Sponge STYLE R-451 / R431 Black Closed Cell Sponge Black neoprene closed cell (expanded) sponge gasket sheet. Tiny individual sealed Neoprene Gasket Material - Diaphragm STYLE 0741 Neoprene Duck Inserted Diaphragm Gasket Material Oil-resistant neoprene diaphragm material designed transmit pulsations between gases, air, and fluids. Reinforced with cotton duck to provide structural Strength. Durometer 70±5. Tensile strength 1500 PSI. Elongation 300%. Temperature range -40°F to 220°F Smooth finish. *Gasket materials unlike purchasing steel or wood are made of a blend of materials with a dominant type (such as neoprene) used in a "blend" or "Compound". Always consider the specifications on the material you are ordering if your application is a difficult one. Manufacturer gasket material specifications do vary.

Traditional "clicker presses" are great for larger quantity jobs and have been the standard in the industry for years. The biggest down side to using clicker presses is tooling must be made to produce a gasket. Just as CNC lathes revolutionized the machining industry, laser cutters, routers and water jet are all computer controled ways of cutting a gasket with out the need for tooling or dies.
Specialized sealing products like Grafoil® flexible graphite, FKM, Ameri-lon®, Kalrez®, Chemrez®, and more common materials for cut gaskets like: PTFE, filled PTFE, FKM, Viton®, silicone, rubber, buna, EPDM, cork, fish paper, vegetable fiber, and non-asbestos Cut Gaskets. If you have a cut gasket application that requires more than traditional
solutions, let our team of cut gasket professionals help.
Cut GasketsFills the space between two objects, generally to prevent leakage between the two objects while under compression. Cut Gaskets saves money by allowing less precise mating surfaces on machine parts which can use Cut Gaskets to fill irregularities. Gaskets are commonly produced by cutting from sheet Cut Gaskets, such as gasket paper (beater addition), Non-asbestos, Rubber, EPDM, Nitrile, Buna, Neoprene, Flexible Graphite, Grafoil®, Aflas, Kalrez®, Viton®, Silicone, Metal, Mica, Felt or a plastic polymer such as (PTFE), Peek, Urethane, or Ethylene Propylene (EP). In the past, the Cut Gaskets selected for specific applications may contain have contained asbestos.Today's sealing products manufacturer's in the United States no longer produce or offer any asbestos containing products. Cut Gasketss containing asbestos have been claimed to have caused Asbestosis. Of course it would take the grinding of Cut Gaskets to release the fibers and then the breathing in of those fibers....possible but in the real world this would be rare. Wetting or oiling a gasket before grinding for removal greatly reduces any risk (not grinding is even better). Asbestos Cut Gaskets is still used in most of the rest of the world and is a very effective low cost material. It is usually desirable that the gaskets be made from a material that is compressible such that it tightly fills the space it is designed for, including any slight irregularities. The most common misconception when selecting a Cut Gasketss thickness is to choose a Cut Gaskets that is too thick. The thicker the material the more likely the material being contained can weep through the pores of the Cut Gaskets itself. This is a greater issue with some materials than others. A rule of thumb is to have the material thick enough to compensate for any surface face irregularities and to permit some compression. The required compression for your Cut Gaskets will depend many factors including: 1)Surface area 2)Pressure being sealed 3)Size of bolts (assuming bolts are being used) 4)Number of bolts 5)Condition of the bolts 6)Lubrication on the bolts All must be considered when determining torque. Torque data must be determined using all of the above and should be provided by an engineer. In most cases unless your gasket is a standard ANSI or API flange using Ring or Full Face gaskets torque data will be difficult to come by (due to staffing and the fear of law suits). In most cases the old tighten it tight enough to stop any leaks but not too tight as to completely crush the gasket is generally accepted. Over compression of Cut Gaskets is a common problem with metal gaskets which have mechanically designed recovery built into the gasket. Over compression removes the Cut Gaskets ability to recover. This is also true of expanded PTFE, once over compressed it will have no recovery and therefore will not longer adapt to maintain a seal. The common strategy of "The more compressive load exerted on the gasket, the longer it will last" is generally true of elastomeric materials since elastomers (rubbers) are not compressible but deflect compression. Many materials such as non-asbestos compressed Cut Gasketss and beater addition (ie; Armstrong) materials contain elastomers in the mix of material they are produced from, making them difficult to over compress. One of the more desirable properties of an effective Cut Gaskets in industrial applications is the ability to withstand high compressive loads. Most industrial gasket applications involve bolts exerting compression well into the 14 MPa (2000 psi) range or higher. This is why Non-asbestos Cut Gaskets are so widely used in industrial Cut Gaskets applications. American Seal & Packing Gaskets of all types, Including: PTFE, compressed non-asbestos, vegetable fiber, beater add, cork, and various rubbers - Nitrile, Buna-N, SBR, EPDM, Viton®, FKM, Hypalon, Aflas®, natural rubber, closed cell, open cell, Neoprene, GRAFOIL® Flexible Graphite and other "soft goods". Cut Gaskets can be cut based on your drawing or sample of the gasket you desire. Basic I.D x O.D shapes can be cut by hand however most gaskets require a die. Gasket materials are available in rolls or on pallets depending on type and quantity. Name brands we can provide include; Brand G®, Donex, DX Seal, Mainland Sealing, Klinger, Johns Manville, RM, Detroit, Utex and GRAFOIL® Flexible Graphite among other gasket styles. So, if you want a cut gasket or gasket material so you can cut your own, we can help. Call us directly or order Neoprene gasket materials online today! |
