Look for #5055, #5060 or #5130. If there is moisture in the system, you need to pull a vacuum or you can use the Enviro-Safe Prodry 8 oz concentrate.

If the system will operate for at least 24 hours, Proseal 8 oz concentrate and Prodry 8 oz concentrate may seal the leak. If using the Enviro-Safe Prodry 8 oz concentrate with the Proseal 8 oz concentrate, it is not necessary to pull a vacuum Concentrate is the least expensive option per ounce Can be measured out in individual doses Must have an injector for installation Payment Shipping Returns Payment is required at the time of purchase through payments.
