The Georg Fischer ecoFIT PE100 union is an injection-moulded dismantling joint designed for industrial pressure piping networks operating up to 16 bar. Engineered for process lines, water treatment skids, and equipment hook-ups, this SDR 11 fitting provides a secure, serviceable disconnect point directly before pumps, flow meters, and control valves across diameters from d20 to d63 mm, eliminating the need to cut welded pipework during scheduled plant maintenance.

Technical specifications

The ecoFIT union ensures reliable hydrostatic performance and full pressure retention matching standard SDR 11 PE100 pipelines. It combines high mechanical rigidity with an easily demountable two-part assembly locked by a threaded nut.

• Nominal pressure rating: PN16 (16 bar water at 20 degrees Celsius)
• Dimensional standard ratio: SDR 11 across all variants
• Size coverage: d20, d25, d32, d40, d50, and d63 mm spigot ends
• Gasket material: Elastomeric EPDM O-ring for robust radial compression
• Axial retention: Glass fibre reinforced polypropylene union nut

Materials and standards

Every union body is injection-moulded from high-grade virgin PE100 thermoplastic resin to guarantee chemical resistance and long-term durability. The union nut is moulded from glass fibre reinforced polypropylene, offering high tensile strength to sustain continuous axial loads without deformation.

The integrated EPDM O-ring delivers dependable elastomeric sealing across industrial water circuits, utility systems, and neutral chemical media. By relying entirely on mechanical compression between precision-machined face contours and the elastomer seal, the joint requires no adhesives, pastes, or solvent cements. After maintenance or replacement of adjoining equipment, the fitting is reliably resealed simply by retightening the reinforced union nut to its specified position.

Installation and jointing

The ecoFIT union features extended spigots engineered for integration into PE100 systems using standard thermal fusion technologies. The fitting is fully qualified for conventional butt fusion according to DVS 2207 welding guidelines as well as Georg Fischer IR Plus infrared fusion methods.

Because its spigots follow the exact jointing parameters of standard PE100 pressure fittings, installers can weld the union into pipe spools using the same thermal cycle without changing machine tooling. For proper operational longevity, piping must be supported adequately to prevent excessive bending moments or misalignment from transferring onto the threaded connection. During reassembly, inspecting the EPDM O-ring and tightening the glass fibre reinforced polypropylene nut by hand followed by standard strap-wrench snugging ensures a leak-free mechanical joint.
