Using only A grade materials and manufactured to tight tolerances for threads, clearances and sealing surfaces, Heldon brass fittings are ideal for the demanding requirement of modern refrigerants.

Heldon fittings are chemically cleaned for contaminant-free installations.

Heldon's Frost Proof series of flare nuts are the ultimate solution and a must where condensation and frosting could lead to pipe damage or nut creep.

Heldon's range of forged flare nuts are stronger than machined nuts and will withstand maximum system pressures. Schrader valves used in all Heldon fittings feature Heldon seats that are suitable for all fluorinated refrigerants up to an SWP of 4,200 kPa.
