RLS Press Fittings take the danger of an open flame out of the workplace, creating a safer work environment with no fire hazards. That means there’s no need for hot work permits, fire spotters or fire-related safety equipment. No brazing also means no need to nitrogen purge, and no need to transport gas and other brazing equipment to the job site.

Plus, as the use of flammable refrigerants in the HVAC and refrigeration industries continues to increase, the safety of flame-free RLS Press Fittings will become even more important.
