Cork & Rubber Gasket Materials

Accurate Felt & Gasket (AFG) manufactures custom gaskets using a variety of cork and rubber materials. We are also a materials master distributor, and can provide cork and rubber materials for any application and in any quantity you may need. We offer die cutting, slitting, and other services to provide gaskets and cork and rubber materials that meet our customers’ unique requirements.

Amorim Cork & Rubber Materials

AFG stocks a variety of products from Amorim. Amorim is the world’s largest producer of cork products. With nearly 150 years of experience, this Portuguese company distinguishes itself through the quality and innovation that goes into its products and its ability to anticipate and respond to market needs.

ACCOSEAL® Products

ACCOSEAL® products are especially effective in metal-to-metal joints where a gasket fits into a machined groove in a flange. If material of the proper firmness is selected, no allowance for side flow is needed. Compressible ACCOSEAL cork and rubber materials can take the place of more expensive (and non-compressible) molded rubber O-rings.

ACCOSEAL® materials retain some of the friction of cork, which helps to reduce slippage or extrusion of gaskets.

ACCOSEAL® cork and rubber materials will easily conform to and compensate for minor flange irregularities. This is especially helpful for applications where the bolt load is low.

ACCOSEAL® materials exhibit excellent resilience, which provides resistance to compression set and other fatigue effects. ACCOSEAL cork and rubber gaskets are more resistant to aging than standard rubber gaskets.

Accurate Felt & Gasket offers the following ACCOSEAL® cork and rubber materials:

 

DC-100:  A general-purpose gasket and sealing material with high cork content and minimum side flow.

 

DC-113:  Firmer than DC-100, DC-113 is made with higher cork content for narrow gaskets, instrument bezels, and the like.

 

DC-167:  A top-quality, soft, and highly compressible material for low bolting pressure applications.

 

DC-179:  A cost-effective, highly compressible material similar to DC-167.

 

DC-203:  Low cost, easily compressible cork and rubber material.

 

DC-205:  An economical, highly compressible material that offers moderate oil resistance.

 

DK-149:  A highly compressible material that resists fatigue. Ideal for cushion pads and low sealing stress requirements.

 

LC-800:  This cork-and-silicone material offers outstanding flexibility and resilience over a broad temperature range.

 

NC-709:  Soft, highly compressible material with maximum oil and solvent resistance. Ideal for low bolting pressures.

 

NC710:  This material provides medium compressibility with maximum oil and solvent resistance. UL-listed.

 

NC-711:  Low compressibility, but with maximum oil and solvent resistance. NC-711 is UL-listed.

 

NC-733:  This special friction material performs well in a wide range of wet or dry friction applications. It is ideal for applications ranging from printer drives to heavy-duty agricultural tractor transmissions. Designed to withstand pressures below 6.33 kg/cm2.

 

NC-775:  High quality and low compressibility, with good oil resistance.

 

NK-730:  Similar to DK-149, NK-730 offers maximum resistance to oils, solvents, and fuels.

TECHSEAL® Products

TECHSEAL® cork and rubber materials offer unique characteristics for a wide range of industries and applications, from oil and gas to automotive to electrical equipment. TECHSEAL products combine the compressibility and recovery capabilities of cork with the flexibility and shelf life of rubber, making them an excellent solution for sealing applications.

TECHSEAL® materials are manufactured with a variety of binders in a banbury process. Nitrile and neoprene are the most common, but other specialty binders such as silicone and polyacrylates are sometimes used to enhance material performance.

Accurate Felt & Gasket offers the following TECHSEAL® cork and rubber materials:

 

CR-55R:  An economical material with good oil sealing properties and resistance to environmental deterioration.

 

CR-75:  Medium-firm material with good heat capabilities and resistance to many fuel blends.

 

HC-50:  Offers high compressibility, good oil resistance, and low swell when used with fuels and oils. Ideal for applications with low bolt pressures.

 

HC-60:  This material provides medium compressibility and good oil resistance. It performs especially well with fuel and oil exposure at medium bolt pressures.

 

HC-80:  Low compressibility and good oil resistance. Ideal for high bolt pressure applications such as automotive fuel pump and meter applications.

 

NC-60:  High quality, medium compressibility material with good oil resistance. Ideal for air or refrigeration compressors.

 

NC-80:  A firm material with high tensile strength and tear resistance and low compression set. Exhibits high heat resistance and moderate swell in fuels and oils.

 

NCA-45:  This material offers medium oil resistance and is ideal for most automotive and sealing applications, such as valve covers, oil pans, and transmission pans.

 

NCA-50:  A good general-purpose sealing material with medium compressibility and oil resistance. Provides good performance in a broad spectrum of applications.

 

SG-601:  Medium-firm material with good heat resistance capabilities and good resistance to many fuels and fuel blends.

 

SP-50:  A very soft material with good oil resistance. Conforms well in applications with flange irregularities and low load pressures.

 

SP-52:  This material provides moderate oil resistance and is ideal for oil sealing in low torque situations. Also commonly used for die ejection, furniture cushioning, and window and door insulation.

 

SP-74:  A versatile, highly compressible material. SP-74 is commonly used for die ejection, noise reduction, matting, cushioning, furniture, and anti-fatigue mats.

 

V-48:  Good resistance to petroleum-based lubricating oils. This material has a high operating temperature (up to 400°F).
