If you have a smaller unit, please contact us. If the a/c system that will not hold a vacuum, you need to 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 mixing with oils and refrigerant can cause you system to make sulfuric acid which will corrode and eat your system! 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. Even though Proseal XL4 can form a seal on the schrader valve, when you hook up to it the seal will release and allow you to use the schrader if necessary. If there is still Proseal XL4 in the system it will reseal the schrader. DO NOT use in ammonia systems DO NOT use in CO2 systems DO NOT use in R410a systems- Pressure is too high and will explode the can- You MUST use the Enviro-Safe Proseal XL4 Direct Inject line of products.
