Low-loss charging T-fitting

Take control of charging on 5/16 in. service fittings.

The CTEE516 MegaSeal Low-Loss Charging-T helps technicians meter refrigerant during the charging process without needing a full manifold or unnecessary hoses. The side port provides a simple way to connect a digital pressure/temperature gauge and monitor system pressures through the whole process.

  • Designed for 5/16 in. service fittings commonly found on ductless systems.
  • Side port allows connection of a digital pressure/temperature gauge.
  • Helps minimise refrigerant loss during charging.
  • Adjustable core depressor can be set for proper core engagement and sealing.
  • Helical barb design makes depressor adjustment easier than straight-barb designs.
