Plastic First-Stage Regulator Dust Cap with O-Ring & String

The cheapest insurance your regulator will ever get. This universal plastic dust cap seals your first stage inlet against water, salt, and grit between dives — the number-one cause of avoidable regulator corrosion. The included O-ring gives a positive seal on standard yoke (K-valve) first stages, and the attached string keeps the cap with your reg so it's always there when you rinse your gear. Toss one in your save-a-dive kit and protect your investment.

Pairs well with: the Save-a-Dive O-Ring Kit, the Marine Sports Master Tool, and Marine Sports Regulator Cleaner.
