This is a teflon tape. I've never used it in the past, but I'm pretty sure my experience with things has been the same. You wrap it around the fitting. Maybe you'll do it again. Maybe one more time. The tape does not look like duct tape, if mixed up it may move a little. He does what he needs. For myself I've fitted an air line up to 125psi and the tape does a pretty good job of creating a seal where simple makeup won't do. As far as I can tell there is nothing special about this product, but it works and it is good value.
