Will recovery machines and gauges from R-410A work with A2Ls, or is tool replacement unavoidable?
To work with A2L refrigerants safely, think about getting new A2L-rated tools instead of trying to use your old R-410A ones.
Most R-410A recovery machines and gauges are not rated for A2Ls because of mild flammability; using them risks leaks or fire. Certified A2L-compatible recovery units, hoses, and gauges are generally unavoidable for compliance and safety.
