Description

Pro Seal XL4, Professional Strength Stop Leak for Home & Industrial Systems
DO NOT USE IN AMMONIA SYSTEMS!
Metal sealer for leaks in a/c condensers, evaporators, line sets and solder joints.
Proseal XL4 is used in home, heat pump and industrial applications.
One can will normally repair a leak in systems up from 1.5 to 5 ton. If you have a smaller unit, please contact us.
If the a/c system is low on pressure, you need to pull a vacuum or you can use the Enviro-Safe Prodry XL4.
The reason for the vacuum or the use of Enviro-Safe Prodry XL4 is that it will eliminate moisture in the system. Moisture causes corrosion and nobody wants that in their system!
If using the Enviro-Safe Prodry XL4 with the Proseal XL4, you do not need to empty the system to pull a vacuum.
For larger units over 5 tons, we suggest you use the Enviro-Safe Proseal XL4 Direct Inject. These are available in various of the larger sizes.
Do NOT use this item in a R410a system. You MUST use the Enviro-Safe Proseal XL4 Direct Inject line of products.
