Spearit sells only the highest quality natural rubber latex tubing. This tubing is manufactured in the U.S.A. by Kent Elastomer using the dip method. Dip manufactured natural rubber tubing has elastic qualities superior to extruded tubing or tubing made from other synthetic elastomers. One of the consequences of dip manufacturing is that the tubing is sold in random lengths by the manufacturer. We receive the bulk tubing and immediately sort it by length and package it in sealed opaque plastic bags to preserve freshness. Then we ship it to Amazon warehouses where our inventories are kept small and replenished as often as weekly. This is important because natural rubber is a perishable product for which proper storage and age matter. Although our primary focus is spearfishing accessories, many of the products we sell have a myriad of other applications. This is the same material used in healthcare and laboratories where it is more commonly referred to as surgical tubing. It is also the preferred material for applications requiring superior elastic properties. Natural rubber tubing is perfect for these and thousands of other applications and Spearit provides the highest quality and freshest rubber available.
