This dual o-ring sealing cartridge (OD) is used for down hole drilling equipment due to its reliability. Its 13X short lip with the OD/ID back scrapers creates a longer life span and better sealing capabilities. The back-to-back KS 13X series creates a bi-directional seal.

This anti-blowout seal is designed with a protective case of hard plastic or metal to be used for rotating valve applications (i.e. butterfly or ball valves). It is also used for applications that require periodic shaft engagement and disengagement to the seal.

This seal set is designed to fit all valve gland diameters. The seal on one side combined with the EH acts as a bearing to seal gas, water mixtures, or glycol and oil from 100 to 392º F and 290 to 5990 psi. This creates a reliable oscillatory function.

This seal is designed for low-pressure applications on the ID where accommodations are needed for the shaft’s angular and radial front. This is used to seal HPLC fluids at –4 to 40º F at 100 psi in a plunger pump.
