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. Flared connections up to ¾” can have a SWP of 4,200 kPa, depending on the size and temperature range from -50°C to +120°C.

• 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 Heldoprene™ seats that are suitable for all fluorinated refrigerants up to a SWP of 4,200 kPa.
