🔧 Professional Mobile A/C Leak Sealer – Shop Pack
ProSeal is a professional-grade A/C leak repair additive designed to seal minor leaks in mobile air conditioning systems. This 12-pack of 4oz cans is ideal for shops, fleet maintenance, agricultural equipment service, and high-volume automotive use.
Once installed, ProSeal circulates with the refrigerant and forms a durable seal at the leak point — helping restore cooling performance without replacing costly components.

💡 Smart Schrader Valve Feature
ProSeal can seal leaking Schrader valves — but it will not permanently block servicing.
🔓 When gauges are connected, the seal releases
🔁 If product remains in the system, it will reseal automatically
💧 For Best Results
Moisture can prevent proper sealing and cause corrosion.
👉 For maximum effectiveness, use a moisture remover (such as ProDry) before installing ProSeal.
