These Carbon Steel compression fittings are the perfect touch for your show setup. PTC Fittings seal well with aluminum hardlines, but compression fittings are the best way to guarantee a leak free seal with any type of hardline. Simply insert the hardline, and tihgten the compression part of the fitting, no need to flare the hardline. We also think the finish on these usually looks better on a hardline setup than the brass on the SMC fittings.
