Can the fittings be removed and reinstalled on the same spot of tubing?: The fitting can be installed onto the same spot if the tube is properly sanded and cleaned, removing any etch marks, or replace onto a clean section of tubing.
What is the warranty on SB1 fittings?: A 5?year limited warranty policy which is available upon request.
The SBLM1458 depth gauge only goes up to 5/8” so how do I mark 3/4” & 7/8” tubing?: Part number SBLMDC3478 is a combo tool, combining both a depth gauge and a disconnect tool
Do SB1s need to be replaced when retrofitting to a lower GWP refrigerant?: Yes. The compression set of the super neoprene o?rings may be compromised when transitioning from one refrigerant to another. Always install new fittings.
What is the #1 cause of problems with the SB1 fittings ?: Not reading/following the installation instructions
Can SB1s be used with aluminum, steel or stainless steel tubing?: No, only copper to copper connections
What is the shelf life of the fittings?: The manufacturer sets the shelf life @ 30+ years
Do the fittings need to be insulated after an install?: Yes, just as you would with any other fitting where it would be subject to condensation.
