Apache guide discs are extremely versatile and can perform in bi-directional or uni-directional applications. As with all of Apache products, the Series C disc was speci!cally developed to perform, ef!ciently 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
