PROGEF PP-H Brass Adaptor Union Socket Fusion PN10 Rp

  Datasheet (PDF)

The Georg Fischer PROGEF Standard adaptor union provides a dependable, demountable transition between metric homopolymer polypropylene (PP-H) pipe systems and threaded metallic equipment. Engineered for demanding industrial piping installations, this hybrid fitting combines a metric socket fusion bush made from beta-PP-H with a high-precision brass end piece featuring a parallel female thread Rp according to ISO 7-1. A durable PP-H union nut compresses an elastomeric EPDM O-ring against the seating faces, ensuring permanent joint tightness at nominal operating pressures up to PN10 (10 bar). As an authorised Georg Fischer distributor, BigWeld delivers genuine PROGEF components engineered for high process integrity.

The thermoplastic components are injection-moulded from high-grade isotactic homopolymer polypropylene (β-PP-H). This formulation guarantees outstanding resistance against harsh chemicals, including inorganic salts, diluted acids, and caustic solutions, while exhibiting high notched impact strength and long-term hydrostatic reliability. In compliance with European standards for industrial thermoplastic pressure systems, PROGEF components are designed for a 25-year operational service life with water at 20 degrees C. The brass insert provides mechanical rigidity and prevents thread galling or deformation during assembly with metallic pipe components, valves, and measuring instruments.

Designed for SDR 11 socket fusion systems, the PP-H socket end integrates seamlessly into d20 through d63 metric pipelines using standard socket fusion welding equipment, creating a leak-proof, fully homogeneous joint. The separable union construction enables rapid dismounting of equipment for inspection, maintenance, or recalibration without sectioning fixed pipework. This makes the PROGEF PP-H to brass adaptor union an optimal choice for industrial utility lines, chemical processing systems, industrial water treatment plants, and dosing skids where dependable plastic-to-metal transitions are strictly required.
