As with all of Apache products, the Series MDK disc was specifically developed to perform, efficiently and reliably. To enhance durability, it’s made from Reliathane, Apache’s special blend of wear-resistant polyurethane.

To enhance disc life, guide discs are available with a variety of wear-resistant additives. In fact, Apache developed a proprietary chemical resistant urethane to help protect against conditions, such as hydrogen sulphide, encountered in severe environments.
