RLS® refrigeration press fittings offer OEMs and service technicians significant advantages over brazing, including:
By eliminating the need for an open flame, RLS press fittings create a much safer working environment, both in a manufacturing facility and in the field. This fact will become even more important with the increased use of flammable refrigerants. In addition, the flame-free connections mean contractors no longer need to haul heavy, bulky acetylene tanks to service calls…and can now easily make needed repairs onsite where flames are not allowed, such as in hospitals.
Using the RLS press tool and jaws, a typical RLS connection can be made in less than 25 seconds, resulting in labor savings of up to 77% over brazing, as shown in independent testing. This comparison only includes the time required to make the actual joint (as in a manufacturing environment). If the time to transport and connect acetylene tanks, as in a field repair, were included, the time savings would be much greater.
Better Quality and Consistency
Unlike brazing, which relies on human performance, the RLS fitting, tool and jaw result in a repeatable and reliable mechanical connection every time — as well as a perfectly clean joint inside and out. Plus, in independent third party testing, RLS joints showed a certified maximum leak rate approximately 1,900 times better than the industry standard definition of “hermetically sealed.”
Lower Total Installed Costs
With the labor savings, combined with the elimination of brazing materials, tools and gas — as well as potential cost reductions in insurance and permits — RLS fittings offer significant total installed cost savings compared to brazing.
No Special Tube Prep or Sealant
With RLS press fitting connections, the tube is prepared exactly the same way as it is with brazing (cutting, deburring, etc.). The fittings do not require any additional preparation. Also, unlike other aluminum connection systems, they do not require the application of a sealant, which can result in joint failure due to human error.
