Modular surface mount manifold assemblies

A connection fitting having an internal fluid passage with inlet and outlet ends, consists of primary and secondary elbow fittings. The inlet end is in fluid communication with outlet port of primary fluid component and the outlet end is in fluid communication with inlet port of secondary fluid component. Several metallic seals made of elastomer, plastic, rubber polymer or nickel interposed, seals the U-shaped internal passage of bridge fitting with the port of fluid. One or more fluid components (12-14) has a single port. A primary and secondary elbow fitting has respective end connected to a fitting located between the elbow fittings. Each elbow and the fitting have an internal fluid passage in fluid communication with each other. The internal passage has an inlet end and primary and secondary outlet ends. The outlet ends of fluid passage is in communication with inlet port of secondary and tertiary fluid component, respectively.
