O‑Ring MoS₂ (molybdenum disulfide) Powder Coating is a durable dry-lubricant treatment applied via tumbling or powder coating to elastomer O-Rings, forming a thin MoS₂ film. MoS₂ coatings enhance O-Ring durability and operational smoothness without altering dimensions or base material properties, delivering reliable, low-friction performance in dynamic systems for extended service life.
