Installing a compression manifolds requires no PEX tools. In this category you will find Sioux Chief compression manifolds. Manifolds are traditionally used in PEX systems, but the manifolds found here will allow easy incorporation into copper or CPVC systems. Use push fittings to install these manifolds anywhere in a plumbing system. All manifolds have a 1" trunk with 3/4" tube inlets & outlets and 1/2" push-fit ports (2" on center). Sioux Chief compression manifolds equipped with balancing valves can also be found here.
