If you're looking to connect a few fittings or hoses together for a natural gas or propane application, then you'll need a little pipe sealant.
This grey pipe sealant tape works on brass and chrome fittings alike, along with stainless steel pipe, cast iron, PVC, CPVC and ABS pipe, and gas connections.
Trust us, the last thing you want your gas appliance to do is to catch fire. Thus, a little pipe sealant can go a long way. Just snag a few packages of Hercules Megatape and you'll be good to go for your natural gas installations.
