It is compatible with all refrigerants (except ammonia) and is compatible with all oils. **Q: How does the Leak Saver work?** A: After injection, The Leak Saver sealant circulates throughout the system with the refrigerant. If there is a small leak, the sealant reacts with the moisture and oxygen at the leak site to form a permanent "scab-like" seal. **Q: What do I need to install the Leak Saver?** A: To inject the Leak Saver, you will need either a basic set of manifold gauges or our Leak Shot injector.
