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, routers and water jet are all computer controled ways of cutting a nitrle gasket with out the need for tooling or dies.

Specialized sealing products like Grafoil® flexible graphite, FKM, Ameri-lon®, and more common materials for cut gaskets like: PTFE, filled PTFE, FKM, Viton®, Expanded PTFE, 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.

Manufacturers we represent

FMI-SPA, Thermoseal, Utex Industries, JM Clipper, Sepco, Pure Flex,  Parker, Leader Gasket.

Though trading partners we can also offer Flexitallic, Garlock, A.W. Chesterton, Durlon, and other major brands.

Cork Cut Gaskets 

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:

1)Nitrile Gasket Surface area
2)Pressure being sealed by Nitrile Gasket
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 not true of Nitrile, once compressed it will have recovery and therefore will 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. 

One of the more desirable properties of an effective Cut Nitrile 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 where a nitrile gasket does not require such load.

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. Name brands we can provide include; FMI-SPA, Klinger, Johns Manville, RM, Detroit, Utex and GRAFOIL® Flexible Graphite among other gasket styles. So, if you want a cut Nitrle gasket or gasket material so you can cut your own, we can help.
