One-Time Connector - 1/4" Female w/Port
One-time connectors are the perfect solution for system pre-charge with a minimum of cost and bulk. The new fittings use a thin metal membrane to prevent leakage prior to connection. Once they are soldered into place, the line may be safely evacuated and charged. This membrane is automatically punctured when the two halves are mated. Once connected, they cannot be disconnected without loss of refrigerant.
One-time connectors are available in two sizes, with and without 1/4" male flare charge ports. All fittings come with plastic dust caps.
