FLAME-FREE FITTINGS FOR A SAFER, EASIER FUTURE
With the industry transitioning to flammable refrigerants, contractors using RLS will benefit from
offering and promoting flame-free service. The RLS press fitting system puts you in a flame-free
work environment, which means hot work permits and fire spotters are no longer necessary. Plus,
there’s no need to nitrogen purge, or to drag heavy brazing equipment to the job site. Add up all
the benefits – safer conditions, no fire hazards and increase efficiencies – and you’ll see that RLS
can mean big cost and time savings, with far fewer headaches.
