PROGEF PP-H adaptor union d20-63 PN10 socket fusion male R

  Datasheet (PDF)

The Georg Fischer PROGEF Standard adaptor union d20-63 provides a robust, detachable transition between metric polypropylene homopolymer (PP-H) piping networks and threaded metallic equipment. Engineered for demanding industrial environments, this PN10 transition fitting pairs a beta-PP-H socket fusion bush and nut with a galvanised malleable iron male R threaded insert. It delivers a reliable, pressure-tight connection for pumps, valves, and headers in chemical processing and industrial water treatment installations.

Technical specifications

This transition fitting operates safely at a continuous nominal pressure of PN10 (10 bar) in water service at 20 degrees Celsius, with an engineered operational design life of up to 25 years. It connects metric pipeline dimensions from d20 up to d63 to BSP taper male threads from 1/2" to 2".

• Nominal pressure rating: PN10 (10 bar) at 20 degrees Celsius for water and industrial media.
• Dimensional range: Outer diameters d20 to d63 mm with male thread connections R 1/2" to R 2".
• Joint configuration: Metric socket fusion connection on the plastic side and external taper thread on the iron insert.
• Thread standard: External taper pipe thread compliant with ISO 7-1 (thread R).
• Sealing system: Replaceable elastomeric profile O-ring seal ensuring airtight and watertight joint integrity.

Materials and standards

The adaptor union is constructed from high-grade isotactic beta-PP-H and hot-dip galvanised malleable iron, engineered for superior mechanical strength and chemical stability. The thermoplastic components exhibit exceptional resistance to stress cracking and hydrostatic pressures, outperforming conventional polypropylene materials in industrial processing.

Manufactured by GF Piping Systems, the plastic union bush and union nut comply with strict European dimensional and material specifications for pressure piping. The metallic end piece is precision-machined from robust galvanised malleable iron, safeguarding the thread profile against deformation and torsional stresses during mechanical joint makeup. Internal sealing is achieved via an elastomeric EPDM O-ring conforming to EN 681, providing dependable chemical resistance and long-term elasticity across cyclic pressure fluctuations.

Installation and jointing

Connecting this adaptor union requires standard socket fusion jointing on the plastic side and controlled mechanical tightening on the metallic male thread. The socket fusion method creates a homogenous, permanent joint with SDR 11 metric PP-H pipes, ensuring leak-free performance under full operating pressure.

The detachable union design allows quick disassembly for servicing, cleaning, or component replacement without cutting the permanent plastic pipeline. As an authorised Georg Fischer distributor, BigWeld supplies the entire PROGEF Standard product line across Europe, providing technical engineers and installers with high-integrity jointing components for mission-critical industrial applications.
