This two-way series is a thread together, minimal spillage, minimal inclusion coupling designed for refrigeration, air conditioning, gas and liquid transfer applications. The dry break design minimizes fluid loss and air inclusion and the threaded connection permits connecting and disconnecting under pressure. This series interchanges with refrigerant coupling that exist on the market and are available in brazed or threaded end connections. The male half can be bulkhead mounted. Accessories include 37º (JIC) adapters in steel; braze adapters; O-rings for adapters; and dust caps and dust plugs.
