Compatible With Major Brands Comes in Supplying Demand packaging. SB1s can only be used with copper to copper connections - not aluminum, steel or stainless steel tubing. As with any other fitting where it would be subject to condensation, the SB1 fittings need to be insulated after an install. Not reading/following the installation instructions carefully is the #1 cause of problems with the SB1 fittings. SB1s need to be replaced when retrofitting to a lower GWP - the compression set of the super neoprene o-rings may be compromised when transitioning from one to another. The fittings can be removed and reinstalled on the same spot of tubing if the tube is properly sanded and cleaned. No brazing, tools or nitrogen purge needed for installation.
