Bottle filling seal rubbers were one of the first products produced by E.J. Whitney Co. Over 30 years of production has spurred innovative new designs and manufacturing processes that have revolutionized the bottle filling industry. Bottle filling seal rubbers are custom made for use on US Bottlers Machines and many others. These seal rubbers are made from silicone for their superior temperature characteristics and high chemical resistance. Seal rubbers can be designed for slip-on or clamp-on applications with or without a vacuum breaker rib. Silicone seal rubbers maintain their seal and integrity from 0 - 375 degrees F. Polyurethane seal rubbers are also available for certain chemical packaging applications. Bell guides are custom manufactured for many machines including US Bottlers Machines. For cold fill applications a proprietary high quality mixed polyurethane is used. Hot fill applications are made with a special silicone.

The E. J. Whitney Company has been producing high quality label gripper sponges to fit Krones Inc., KHS USA, KHS AG, KHS Ancher, P.E. USA Inc. and other labelers for over ten years. E.J. Whitney Co. gripper sponges are made of non-stick silicone that collapses like a sponge by design. The non-stick silicone label applicator keeps glue from sticking to the surface for longer service intervals before clean up. Also, during clean-up the gripper sponge does not absorb water or other cleaning agents. Most clients have converted 100% of their label applicators to the E.J. Whitney Co. gripper sponges. These label applicators work very well with PET or glass packages and are proven on the fastest and slowest labeling lines. Ordering is very simple and only one phone call away. All that is needed is some basic information about the application of the gripper sponge and one new sponge for gathering the dimensions. Tooling and production of the first article will take approx. two to three weeks depending on workload.
