The Concentric Crimping Technology is patented and unique to RLS!
RLS fittings have a unique copper grain structure
The RLS fitting(3) is made from soft annealed copper, that allows the Concentric Crimping Jaws(4) to apply even pressure with precision. The jaws perfectly mould the fitting around the copper tube(1), resulting in a repeatable and truly leak-free joint.
RLS’s jaw profile is unique
The unique RLS Concentric Crimping Jaws(4) apply perfectly even pressure all around the o-ring(2) and copper tube(1).
