A coupling body having an opening and configured to receive a pipe in the opening. The coupling body is made of a metal material and the pipe is made of a different metal material to the metal material of the coupling body. An insulating sleeve lines at least a portion of an inner periphery of the coupling body adjacent the opening. The insulating sleeve is made of non-metallic material and is configured to serve as a physical non-metallic barrier between the metal material of the coupling and the different metal material of the pipe so the different metal material of the pipe does not contact the metallic material of the coupling body.

No contact connectors

The present disclosure provides a pipe coupling that includes a coupling body, a first pack joint nut, and first and second sleeves. The coupling body is made of a first metal material and the first pack joint nut is made of a second metal material. The first pack joint nut is configured to receive a portion of a first pipe. The pipe is made of a dissimilar metal material to the first and second metal materials of the coupling body and the first pack joint nut, respectively. The first sleeve is configured to line at least a portion of an inner periphery of the coupling body. The second sleeve is configured to line at least a portion of an inner periphery of the first pack joint nut. The first and second sleeves are made of non-metallic materials, and serve as physical non-metallic barriers between the first/second metal materials of the coupling/first pack joint nut, and the dissimilar metal material of the first pipe.

An angled check valve assembly having a housing with inlet and outlet passageways angled with respect to each other, and a spider spacer cage at a location which allows flow through the inlet passageway into the spider spacer cage where the flow is then angled and directed through the outlet passageway. One of the passageways has one-way check valve(s) therein to insure one-way flow from the inlet through the outlet passage. An installation entry is provided in the housing for insertion of the check valve(s). The installation entry is sealingly closed by a threaded closure member. The spider spacer cage is rotatable relative to the threaded closure so that, as the closure member is moved inwardly, at least one opening (in the side of spider spacer cage) can be kept in registry with one of the passageways. The spider spacer cage also forces the one-way valve(s) toward an abutment in the housing. The spider spacer cage is indexed to one end of the one-way valve(s), and the valve(s) are indexed to each other and/or the housing, to prevent the closure from moving axially to seal the entry when the one-way valve is inserted upside down so as to prevent flow from the inlet through to the outlet.
