Frequently Asked Questions

AI
Most O-ring kits cover the most common sizes used in standard regulators and tank valves, but you should always verify the specific diameter and material (such as NBR) against your manufacturer's specifications.
Valve caps protect the threads of your tank valve from debris, salt buildup, and accidental impact, which prevents leaks and ensures a secure connection when attaching your regulator.
O-rings should be inspected before every dive. If you notice any cracking, flattening, or signs of wear, replace them immediately to avoid air loss or equipment failure underwater.
