90851075 - 3/4" ID Natural Gum Rubber Tubing - Tan

Superior Elasticity and Abrasion Resistance

The RBR GUM NAT TAN .750 ID .125WL is a premium-grade natural gum rubber tubing designed for a wide array of industrial and laboratory applications. Distinguished by its classic tan color, this tubing is manufactured from natural rubber (polyisoprene), a material renowned for its exceptional physical properties. Unlike synthetic alternatives, natural gum rubber exhibits a unique combination of high tensile strength, superior elongation, and outstanding resilience. This 'memory' allows the tubing to stretch significantly and return to its original shape without permanent deformation, making it an excellent choice for dynamic applications involving vibration or repeated compression.

With an Inner Diameter (ID) of 0.750 inches (3/4") and a robust Wall Thickness of 0.125 inches (1/8"), this tubing offers a substantial flow path while maintaining enough structural integrity to resist kinking and collapsing under moderate vacuum or bending. The 1/8-inch wall also provides a layer of cushioning, making this product suitable for use as protective sleeving over delicate cables or hard piping. One of the standout features of natural gum rubber is its resistance to abrasion and tearing. It is frequently employed in systems that transport slurries, sand, or other fine particulates, as the soft rubber absorbs the impact of particles rather than wearing away, outlasting many harder materials.

It is important to note that while natural rubber excels in mechanical flexibility and acid/alkali resistance, it is not recommended for use with petroleum-based oils, solvents, or hydrocarbons, which can cause swelling and degradation. Additionally, prolonged exposure to direct sunlight (UV radiation) or ozone should be avoided to prevent cracking. For general fluid transfer, low-pressure air lines, and mechanical fastening applications where grip and flexibility are paramount, this natural gum rubber tubing is the industry standard for reliability and performance.
