Frequently asked questions
Why do O-rings fail in drilling equipment?
O-rings fail due to chemical degradation from hydraulic fluid, extreme temperature cycling, excessive pressure spikes, improper installation (twisting or pinching), and age-related hardening. Using the correct material compound for each application is critical.
