## Description

### RLS 3/8" Refrigerant Copper Press Cap

#### Original. Patented. Proven.

RLS Refrigerant Copper Press fittings are faster, easier and safer than brazing. They connect in seconds with no flame – so no fire hazards, no gas or brazing materials, no brazing equipment, no hot work permits, no fire spotters and no need to nitrogen purge. Converting from brazing to flame-free RLS Press Fittings can result in significant time and cost savings and substantially higher productivity. Eliminating the brazing process means installations can be completed up to 60% faster. The reduced labor costs – combined with the elimination of brazing materials and equipment, fire spotters and hot work permits – results in far lower total installed costs when compared to brazing.
