Adaptor union PP-H brass male thread R PN10

  Datasheet (PDF)

The Georg Fischer PROGEF Standard PP-H brass adaptor union provides a demountable, high-integrity transition between metric polypropylene pipework and threaded metallic equipment. Designed for industrial process piping, chemical transfer systems, and water treatment plants, this PN10 rated fitting enables reliable mechanical connection to metal valves, pumps, and instrumentation. It ensures smooth transitions and convenient maintenance without compromising pressure containment or structural safety across the piping network.

Technical specifications

This adaptor union operates at a nominal pressure of PN10 (10 bar) at 20 degrees Celsius and integrates socket fusion jointing with an ISO 7-1 taper male thread. Engineered for SDR 11 piping systems, the assembly combines thermoplastic chemical durability with the mechanical rigidity required at threaded metal interfaces.

• Product type: Demountable transition adaptor union
• Nominal pressure rating: PN10 (10 bar) at 20 degrees Celsius
• Pipe compatibility: SDR 11 metric PP-H piping
• Jointing methods: Metric socket fusion and taper male thread R (ISO 7-1)
• Operational design life: 25 years with water at 20 degrees Celsius
• Sealing element: High-grade elastomeric EPDM O-ring

Materials and standards

The fitting combines an injection-moulded beta-PP-H socket union bush, a beta-PP-H union nut, a precision-machined brass threaded insert, and a durable EPDM gasket. The isotactic polypropylene homopolymer compound offers exceptional resistance to internal pressure, stress cracking, and aggressive chemical media, while the brass component delivers outstanding dimensional stability and thread strength under mechanical loads.

Manufactured in full compliance with Georg Fischer quality benchmarks and international standards for pressure-bearing thermoplastic systems, the fitting features a taper male thread conforming to ISO 7-1. The integrated EPDM seal maintains continuous tightness under fluctuating thermal and mechanical operating conditions, ensuring leak-free performance over long service intervals.

Installation and jointing

Installation combines standard socket fusion welding on the plastic bush with a threaded mechanical joint on the brass end. The socket fusion process creates a permanent, homogeneous bond with metric SDR 11 pipework, while the taper male R thread connects directly into compatible female metal components using appropriate thread sealant.

The true union design permits rapid assembly, dismantling, and reassembly of adjacent equipment such as pumps, flow meters, or valves during routine servicing. Plant operators can quickly disconnect mechanical equipment or isolate sections for maintenance without cutting or altering the fixed polypropylene pipeline.
