What lubricant should I use on underwater connectors?

คำตอบอย่างรวดเร็ว

Use silicone-based grease (Dow Corning 111 or equivalent) for O-rings. Never use petroleum-based products. Apply thin, even coat to O-rings only – not on electrical contacts. Reapply after each mating.

What NOT to Use

• ❌ Petroleum jelly (Vaseline): Degrades rubber
• ❌ WD-40: Not a lubricant, damages seals
• ❌ Motor oil: Incompatible with O-ring materials
• ❌ Grease with additives: May cause swelling
• ❌ Dielectric grease: Can interfere with connections

Application Procedure

1. Clean: Wipe O-ring and groove with clean cloth
2. Apply: Small amount of grease on fingertip
3. Spread: Thin, even coat on entire O-ring
4. ติดตั้ง: Place O-ring in groove carefully
5. Wipe excess: Remove any grease on mating surfaces

Important Notes

• Never lubricate electrical contacts – causes resistance
• Use sparingly – excess attracts contamination
• Reapply each time – grease washes off
• Store properly – keep grease container sealed
