Environmental seal kit for Agir first stages V9 and V10. A correctly mounted environmental seal kit prevents dust, sand, dirt and water to enter the open (flooded) part of the first stage. This provides added protection for your regulator. It also prevents ice build-up in the open part of the first stage when diving in cold weather.
This sealing kit provides a dry seal, hence alleviating the need for messy silicone grease or alcohol filled first stages.
Highly recommended for cold water diving.
