Usage of HVAC&R press fittings continues to grow as contractors see benefits over brazing

Although plumbing contractors have enjoyed the benefits of press‑to connect fittings since the 1990s, it wasn’t until 2015 that RLS (Rapid Locking System) introduced the first press fittings designed to withstand the high pressures of HVAC and refrigeration systems.

Not surprisingly, many HVAC&R contractors were reluctant to try the new fittings in their early days. But today, after more than 8 years and 15 million fittings installed, RLS press fittings are now in widespread use around the world. Their tremendous growth is due to number of important factors …

FASTER, EASIER, SAFER INSTALLATION

RLS press fittings make reliable copper tube connections in just 10 seconds, saving significant time and labor costs compared to manually brazing joints. Eliminating the use of an open flame also increases safety, and means contractors no longer need to haul heavy tanks and other brazing equipment to and from the jobsite, no longer need to nitrogen purge, no longer need to purchase and stock brazing materials, and no longer need to organize hot work permits.

Proven To Be Reliable And Repeatable

RLS fittings were specifically designed and engineered for the high pressures of HVAC&R, and are UL listed for pressures up to 700psi. Because the battery powered press tool does the work, RLS connections are consistent and repeatable – and only require minimal training – compared to the potential for leaks due to inconsistent manual brazing. And with an 8 year track record of success, contractors can feel confident that RLS joints will be leak free.

UNIQUE TECHNOLOGY, WITH 360° METAL-TOMETAL CONNECTIONS

Unlike the hexagonal press systems used in plumbing, the patented RLS press technology uses a double circular press – featuring two 360 degree metal to metal connections. Plus, the fittings start as soft copper and are work hardened during the press, creating a permanent bond to the tube. The circular press results in a permanent mechanical joint every time, with no potential leak paths.

A Wide Range Of Tool And Jaw Options

With RLS compatible jaws now manufactured by a range of companies, RLS fittings can be pressed with most 19kN, 24kN and 32kN press tools on the market – from popular brands like RIDGID, Milwaukee, Klauke, Rothenberger, Viega, Dewalt and others. That means contractors who already own a press tool only need to purchase the jaws (only in the sizes they use) to enjoy the time saving benefits of RLS fittings.

A Complete Product Line

RLS offers fitting sizes from 1/4" to 1 3/8" and a full range of products, including couplings, long radius 90 degree and 45 degree elbows, tees, reducers and much more. In addition, RLS supplies all the necessary tools and jaws, both individually and in convenient kits.
