Pipex 9790115535 8 Inch SDR11 Butt-fusion Flange Adapter

Product Description

The PIPEX 9790115535 is an 8-inch SDR11 butt-fusion flange adapter engineered for polypropylene piping systems. This fitting connects polypropylene pipe runs to flanged equipment, valves, or transition points using a heat-fusion joint at the pipe end. Built from the same polypropylene material used throughout Aquatherm piping systems, it ensures a consistent, chemically compatible joint when fused correctly. The SDR11 dimension ratio indicates a pressure-rated wall thickness suitable for demanding fluid handling applications. A minimum 1/8-inch thick gasket is recommended at the flange face; no gasket is included. Licensed plumbers and pipefitters working on commercial or industrial polypropylene piping systems are the primary installers of this fitting.

This flange adapter is designed for use in polypropylene pressure piping systems, including hydronic heating, cooling, and industrial process piping installations where a flanged transition is required. It is butt-fused to pipe in the field using standard polypropylene heat-fusion equipment. Pipe and fitting sizes range from 1/2 inch to 24 inches within the Aquatherm polypropylene product family, and the heat-fusion principles remain consistent across the range. Installers should verify that their butt-fusion equipment is compatible with this fitting before ordering, as the fitting length may not accommodate all fusion machines.

Key Features

• 8-inch nominal size with SDR11 wall thickness for pressure-rated service
• Butt-fusion end for a fully heat-fused, leak-free polypropylene joint
• Flanged outlet allows connection to valves, pumps, and equipment with standard bolt patterns
• Made from polypropylene material consistent with Aquatherm piping systems for full material compatibility
• Minimum 1/8-inch gasket recommended at flange face — gasket not included
• Fitting length may not be compatible with all butt-fusion machines — verify equipment before ordering

Compatibility

Designed for use with polypropylene butt-fusion piping systems. Compatible with Aquatherm polypropylene pipe and fittings across the full product line. Verify butt-fusion equipment compatibility with this fitting prior to installation.

Installation Notes

Installation must be performed by a qualified pipefitter or plumber trained in polypropylene heat-fusion techniques. Shut down and depressurize the piping system fully before cutting into any existing line. Use only butt-fusion equipment rated and sized for this fitting diameter; confirm equipment clearance against the fitting length before beginning fusion. Flange bolt torque, gasket selection, and flange class should comply with project specifications and applicable plumbing or mechanical codes.
