PRO TIP
Never use petroleum-based lubricants (like Vaseline) on your O-rings. Petroleum eats away at the rubber, causing it to stretch and fail prematurely. Stick to 100% silicone pool lube!
Always follow label directions and safety guidance. Keep pool chemicals and accessories stored safely and out of reach of children.
