For your health and safety, this brass fitting is made of lead-free brass which contains less than 0.25% lead. Lead-free brass costs about 30% more to manufacture than regular brass. Lead-free brass is also harder, stronger, and more durable than regular leaded brass. Always wear safety goggles when handling or using compressed air.

This heavy duty winterization tool is machined from a solid lead-free brass casting. If you are looking for a quality tool that lasts a lifetime, this one is for you!
