Copper Lock no heat solder

I have used this product for almost a year. I really like the product because I can safely send a maintenance tech into an apartment to repair a leak and not have to worry about an open flame propane or acetylene torch This product works very effectively if the copper pipe is dry. If the pipe is wet it will not always hold and will leak. It works well on low pressure systems like water pipes it will not always hold in HVAC systems as the pressures hit 250 to 350 psig.
