Neoprene Gaskets

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: -
20°F to +170° F. Black color.

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%. 
Temperature Range -30° F to +200° F

Neoprene  Gasket Material - Sponge

STYLE R-451 / R431 Black Closed Cell Sponge

Black neoprene closed cell (expanded) sponge gasket sheet. Tiny individual sealed cells contain inert nitrogen gas to resist moisture, dirt and air even at cut edges. It is this unique structure that makes the closed cell sheet an insulator, sound and vibration damper and shock absorber. Compression deflection 5-13 PSI. Density 15-30 lbs/cubic foot. Water absorption 5% maximum. Temperature range -30°F to +150°F (continuous) (to 200°F intermittent). Tensile strength 150 PSI. Elongation 350%.

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.

When it comes to cutting Neoprene 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.

If you have a neoprene cut gasket application that requires more than traditional solutions, let our team of cut gasket professionals help.

Cut Gaskets 

Fills the space between two objects, generally to prevent leakage between the two objects while under compression. Neoprene cut gaskets saves money by allowing less precise mating surfaces on machine parts which can use Cut Gaskets to fill irregularities. Neoprene gaskets are commonly produced by cutting homogeneous, closed cell or open cell neoprene 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 & EPDM. 

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.

One of the more desirable properties of an effective Cut neoprene gaskets in OEM applications is the ability to recover when compressed. Neoprene is commonly used in low temperature 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".

Neoprene 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;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.
