Big things are coming! RLS is proud to announce the introduction of two larger fitting sizes coming later in 2020. The new RLS XL line will include 1-5/8″ and 2-1/8″ couplings, elbows, tees and reducers. Using the same reliable, flame-free press technology as the current RLS fitting sizes, the new XL line will provide significant time and cost savings to HVAC and refrigeration contractors who install and service larger systems such as those found in grocery stores, data centers and other large facilities.
