More Information
Summary:Disclosed is a fixed orifice expansion device for use in connection with couplings, such as refrigerant couplings. The novel device includes a body having first and second ends, and an orifice therethrough. At least one end of the body includes a sealing mechanism for sealing the device within a bore of a cooperative coupling or the like, while the opposing end includes means for installing the body within the cooperative coupling. By use of the disclosed expansion device, a service valve for refrigerant expansion may be accomplished with three standard ARI fittings.
