Made of high‑strength wear‑resistant metal material, the ring is finely turned and polished with strict dimensional tolerance. It withstands high‑pressure mud impact during mud‑pump operation and provides reliable leak‑proof sealing performance for both static and dynamic working conditions. It effectively prevents mud and oil leakage from component gaps and protects core assemblies such as Crosshead Assembly from erosion.
Featuring outstanding mud‑corrosion resistance, wear resistance and high‑temperature resistance, it adapts well to harsh high‑vibration oil‑field drilling environments. Custom outer‑diameter and cross‑section sizes are available to match most mud pump fluid‑end and power‑end assemblies. As a vital sealing consumable among Mud pump parts, it is easy to replace and delivers stable sealing performance, greatly cutting leakage‑related breakdowns and downtime losses during petroleum‑drilling mud circulation work.
