Brass Hex Cap
In climates where there are freezing temperatures, trigger valves can crack from freezing water expanding inside the valve. Installing a Brass Hex Cap on your Stainless Soft Touch Valve can prevent this damage. The reason is that brass is weaker than stainless so this brass hex cap will fail before the stainless valve will similar to a freeze plug on your engine. Get it. Install it. Forget it. Another problem solved.
