The FatSac Check Valve and Adapter is an optional upgrade for FatSac ballast bags that replaces the standard Quick Twist Adapter.

Features:

• Air Inflation Valve - simply use a standard air pump to inflate
• Includes all O-rings needed, and by-pass adapter fitting for emptying water
• Manual 1 way check valve when manually filling bags with Supa Pump
