Stop Small Leaks Before They Become Big Repairs 💨❄️
Enviro-Safe ProSeal™ is a professional-grade mobile A/C additive designed to seal minor leaks in automotive and equipment air conditioning systems — without tearing apart your system or replacing expensive components.
This easy-to-install aerosol circulates with your refrigerant and forms a durable seal at the leak point on metal surfaces, fittings, valves, and joints.
If your A/C is slowly losing performance from a small leak, ProSeal may be the solution you’ve been looking for.
🔧 What Does ProSeal Seal?
ProSeal forms a hard seal on:
-
🔩 Metal components
-
🔄 Schrader valves (reseals after service!)
-
🧵 O-rings & gaskets
-
❄️ A/C condensers
-
🌬️ Evaporators
-
🔗 Line sets
-
🔥 Solder joints
✔ Repairs most minor leaks in mobile A/C systems
✔ Circulates through the system and seals at the source

💡 Smart Schrader Valve Technology
Even though ProSeal seals Schrader valves:
🔓 When you connect service equipment, the seal releases
🔁 If ProSeal remains in the system, it will reseal automatically
This allows future servicing without permanently blocking the valve.
💧 For Best Results
Moisture prevents proper sealing and causes corrosion.
👉 We strongly recommend using Enviro-Safe ProDry BEFORE ProSeal to remove moisture from your system for maximum effectiveness.
