PE100 Large-Diameter Branch Saddle | Under Strap | Manual Pin | 110/125mm Outlet | SDR 11-26 | Water PN16 / Gas 10 Bar | DN225-630 Main | Heavy Branching for Gas, Water, Mining & Wastewater

The large-diameter electrofusion branch saddle with under strap is engineered for heavy branching on larger PE mains, with 110mm or 125mm outlets on main bodies from DN225 to DN630. The sacrificial under strap provides cost- and time-efficient installation while ensuring effective clamping forces are maintained during the fusion cycle on larger mains pipe.

This is a manual pin 4.0mm fitting. Welding parameters are moulded into the body of the fitting for easy reference, compatible with standard Fusamatic electrofusion welding systems. Rated Water PN16 / Gas 10 Bar.

Manufactured from virgin PE100 black polyethylene. Suitable for gas, water, wastewater, irrigation and mining applications. Operating temperature range: −10°C to +40°C.

Covers a wide SDR range of 11–26 (225/250mm bodies: SDR 11–21), making it versatile across different pipe wall thicknesses. 10 standard references in total.

• Heavy main-to-main branch connections in gas distribution networks
• Large bypass and isolation connections on water and wastewater trunk mains
• High-volume off-takes from DN315–630 trunk pipelines
• Mining process water and slurry trunk-line branching
• Large irrigation main branching to secondary distribution

• Under strap fixing — sacrificial strap ensures effective clamping on large mains during fusion; cost- and time-efficient
• Large-diameter range — DN225–630 main bodies with 110/125mm outlets
• Wide SDR coverage — SDR 11–26 (225/250mm bodies: SDR 11–21) for versatility across pipe wall thicknesses
• Manual pin 4.0mm — parameters moulded into the body, compatible with standard Fusamatic welding systems
• Fully welded electrofusion joint — no gaskets, no future maintenance
• Water PN16 / Gas 10 Bar rating (dependent on PE pipe welded)
• Manufactured using virgin PE100 black polyethylene
• Rising pin fusion indicator for easy monitoring of the fusion process
• Permanent batch number + barcode/QR code for full traceability (ISO 13950 / ISO 12176-4)

Note: All stated technical specifications depend on the PE pipe welded to and local pipeline pressure regulations. Under clamp design. Refer to the table above for the SDR rating of each individual fitting. Please contact us for detailed CAD drawings.
