Rubber sealed branch saddle PVC-U 3-6" outlet 2" BS Inch

  Datasheet (PDF)

The Georg Fischer rubber sealed branch saddle PVC-U provides a mechanical branching solution for imperial pressure piping networks. Engineered for utility and industrial piping systems, this saddle connects main pipe runs from 3" to 6" to a 2" BS Inch solvent cement branch outlet. Featuring a durable unplasticised polyvinyl chloride construction and high-grade elastomeric sealing, the component ensures reliable fluid conveyance under working pressures up to 10 bar for water and 1 bar for gas.

Technical specifications

The branch saddle is engineered for pipe take-offs with a solvent cement branch connection while maintaining pressure-tight integrity on the host pipeline. It accommodates system pressures of up to 10 bar (145 psi) for water services and 1 bar (14.5 psi) for gas applications at 20 degrees Celsius.

• Nominal pressure rating: 10 bar water / 1 bar gas at 20 degrees Celsius
• Main pipe compatibility: 3", 4", and 6" nominal pipe diameters
• Branch outlet size: 2" BS Inch solvent cement socket
• Sealing element: Integrated NBR (nitrile butadiene rubber) gasket
• Construction: Mechanical two-part saddle body with radial socket outlet

Materials and standards

Manufactured from robust unplasticised polyvinyl chloride (PVC-U), the saddle features an integrated NBR elastomeric gasket for dependable sealing against the host pipe exterior. The branch outlet dimensions conform to the BS Inch sizing system for direct solvent cement jointing with matching imperial pipes and fittings.

The integrated elastomeric seal provides high mechanical resilience and resistance against industrial process media and non-potable water. The component is not certified according to German KTW-BWGL regulations and is not intended for drinking water installations requiring this approval.

Installation and jointing

Installation involves mechanical clamping around the host pipe with the rubber gasket ensuring a dependable seal, followed by solvent cementing the 2" BS Inch branch pipe into the socket outlet. The rigid shell secures firmly around the main line to prevent leakage without requiring complete line disruption.

Clean pipe contact areas thoroughly prior to positioning the saddle to ensure optimal seating of the NBR gasket. Solvent cement jointing on the branch outlet must follow standard solvent welding procedures using approved PVC-U cleaner and cement.
