Silicone O-Ring Lubricant

This high-quality silicone grease is designed specifically for subsea seals and O-rings. It acts as an excellent sealing enhancer, filling microscopic surface irregularities of the seal groove to improve air and water tightness. The silicone-based material is harmless to most rubbers (NBR, FKM, EPDM), preventing swelling or softening. With excellent thermal stability (-40C to 200C) and chemical resistance, it prevents seals from sticking or oxidizing during long-term storage or operation, essential for assembling marine instrumentation.
