Gum Rubber Gaskets / Natural Rubber Gaskets

Gum Rubber A pure variant of gum rubber made gaskets are used in sand blasting booths. It is made from organic materials and is capable of withstanding high temperature levels. It has self-healing capacity and is weak against sunlight as well as oxygen.

Our company's reputation for excellence has been built on our ability to provide our valued customers with the most effective designing, engineering and manufacturing solutions to meet their most demanding applications. Our main objective is to continuously exceed our customer's expectations by providing them with high performance gaskets and sealing products, competitive pricing, on-time delivery and exceptional customer service.
Natural rubber, also referred to as "gum rubber", has many positive characteristics. It has superior resilience, high resistance to tear and abrasion, tensile strength, good compression set, and molding properties.
Full Floating, natural gum rubber. For installation requiring high tensile and elongation characteristics along with superior abrasion resistance. Gum rubber provides a soft rubber seal. Conforms to irregular flanges with bolt heads. Resists most organic salts, acids, alkalis, and ammonia. Non-marking. Tensile strength to 3000 PSI. Durometer 40+/-5. elongation 600%. Temperature range -20F to 140F. Smooth Finish.
Natural rubber functions well in temperatures ranging from -60F to +175F. Natural rubber should not be used in applications that involve petroleum derivatives or exposure to chemicals.

Die Cut Natural Rubber Gaskets

Die Cut Natural Rubber Gaskets

Die cut natural (gum) rubber gaskets and water jet cut natural rubber gaskets in a wide variety of grades, thicknesses and hardness. The standard thickness of natural rubber ranges from 1/64" to 2" thick. The hardness (durometer) of natural rubber ranges from 40 to 60 durometer.
Die cut natural rubber gaskets are generally tan or black in color with the exception of our premium grade "red" gum natural rubber, which is used when an optimum combination of tear and abrasion resistance are required. Natural rubber gaskets are available with or without pressure sensitive adhesive (PSA) backing.

Molded Natural Rubber Gaskets

Molded Natural Rubber Gaskets

Natural rubber (NR) compounds are available from 20 to 90 durometer, Shore A. Natural rubbers color ranges from translucent (soft) to black (hard), and custom color compounding is available upon request. Natural rubber molding tolerances are complaint with rubber molding industry standard RMA A2 Precision tolerances.
