Hello - We regret that you are not satisfied with the purchase of the Scepter spouts. You mentioned that the spout is very loose in the nut (cap) which I have not heard before. The spouts are designed to be used with Scepter fuel cans only, they will not fit other manufacturers fuel cans, is that the case here? Also, this spout is not designed to be used with our SMARTCONTROL models as they require the SMARTCONTROL spout. There are replacement gaskets available, if your would like some mailed please contact our Customer Care team at 1-855-857-3252 or email customerservice@scepter.ca Thank you
