Metal to Metal Seal vs O-Ring Seal

Historically, the HVAC industry has seen two types of sealing methods used for sealing refrigerant pipes to equipment systems: metal- to-metal seals and o-ring seals.

SmartLock fittings use an innovative metal-to-metal sealing technology that is able to achieve the following benefits over o-ring seals:

  • Highest possible pressure testing and rating
  • Highest vacuum pressure
  • Compatibility with all refrigerants
  • Compatibility with all compressor oils
  • High temperature and low-temperature stability
  • Zero annual leakage rate
  • Lifetime reliability/warranty
  • Compatibility with Copper and Aluminum tubes

Metal-to-metal sealing technology provides the highest integrity sealing solutions for today’s DHP (copper tube made from Alloy C12200) and unitary equipment installations. The elastomeric rings that are placed inside Smart Lock fittings DO NOT make the seal. They are placed for vibration dampening and keeping environmental elements outside. SmartLock fittings submitted for UL certification did not have any elastomeric rings. All internal tests are conducted without the elastomeric rings to uphold SmartLock’s commitment and integrity of metal to metal sealing technology.
