SharkBite Silicone wrap is used on SharkBite brass fittings when buried (push-to-connect and barb). The silicone wrap protects the fittings from contaminates that can be found in soil.
I used this product to wrap the shark bite fittings that were being put under ground. The application looked easy because I had a friend do it for me. We want know if it works for the amount of time it is suppose to until it fails.
