Abstract: A cross-linked polyethylene (PEX) tubing having an aluminum welded tube as reinforcement and method of making PEX tubing disclose tubing having an inner PEX layer and an outer polyethylene layer with an intermediate aluminum tube enveloped by adhesive layers for joining the inner and outer polyethylene layers with the aluminum tube. Carbon black particles are included in the polyethylene material for increasing absorption and dispersion of UV and thermal energy.

Abstract: An insert coupling apparatus or article and method of using is described, whereby the insert coupling includes a plurality of ribs and a plurality of channels formed between adjacent ribs. At least one seal ring is included. A flexible conduit or pipe is positioned on insert coupling sections with at least one crimping ring utilized to crimp the conduit/pipe by compressing the conduit/pipe material into one or more channels provided.
