Temperature:  - 25 F to + 220 F

w       EPDM
(Ethylene-propylenediene  Terpolymer)

Excellent for applications which involve extreme temperature and/or weather conditions.  It is used extensively in high temperature gasket installations.  Offers ozone and chemical resistance as well as resistance to extreme temperatures.  Also provides excellent electrical and dynamic properties.  Excellent resistance to animal and vegetable oils, water, steam, oxygenated solvents.
Temperature:  - 40 F to + 220 F

 w       HYPALON
75 Duro Hypalon rubber compound with a light fabric finish, it has excellent resistance to weathering and ozone, acids, hot water, moderate resistance to petroleum oils and lubricants.  It is not recommended for service in chlorinated solvents, aromatic solvents and ketones.
Temperature:  - 30 F to 250 F

w  NATURAL RUBBER
       (Isoprene, Natural)
Tan Floating Stock (Pure Gum), for installation requiring high tensile and elongation characteristics along with superior abrasion resistance.  Also suitable for applications requiring a soft rubber seal.  Natural rubber conforms to irregular flanges with bolt loads.  Highly resilient excellent abrasion and acid resistance and high tensile and tear strength. Bonds effectively to a wide range of materials. Resists most organic salts, acids and alkalies.  Compound is non-marking and non-toxic.
Temperature:  - 20 F to + 140 F

w       CLOTH INSERTED RUBBER
Excellent flange gasket material for air, hot and cold water, saturated steam, low pressure steam or hydraulic services.  Suited for all types of gauges, meters and valves where pressure areas are subject  to movement.  A tough SBR compound and close weave polyester fabric construction.  Perfect for custom cutting and odd size applications and provides both flexibility and uniform structural strength.  One ply of fabric per 1/16" thickness.
Temperature:  - 20 F to + 170 F

w       CLOTH INSERTED NEOPRENE
Economical answer for flange gaskets where oil and hot or cold water and gases are being conveyed.  A medium grade Neoprene pressed with a close weave polyester inserted fabric.  Good where both flexibility and uniform strength are important.
Temperature:  - 20 F to + 180 F
 

w       DIAPHRAGM
Strong flexible premium packing material used to transmit motions between fluids, gases and air in gauges, meters and valves.  An excellent weather stripping material.  Manufactured with a high quality Neoprene compound for long service.  Reinforced with high quality polyester for balanced structural strength over entire diaphragm area.
