These discs center the sealing discs in the line, which allows the four sealing discs in the center to form a quadruple
seal during displacement.
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.
