We cut Urethane gaskets made from quality Urethane materials to your dimensions.
Urethane sheet gasket material is a Polyethylene-apdate, Poly (oxy-1, 4, butylene) ether material that has Good aging and excellent abrasion, tear, and solvent resistance, but poor high temperature properties. It is resistant to Ozone, hydrocarbons, moderate chemicals, fats, oils, greases. It is attacked by Concentrated acids, ketones, esters, chlorinated and nitro hydrocarbons.
When it comes to cutting gaskets there are several ways to get the job done. 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.

Urethane Cut Gaskets
Fills 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).
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 Gaskets 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:
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 a Cut Gasket 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. 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 Cuts 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".
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. So, if you want a cut urethane gasket or gasket material so you can cut your own, we can help.
