Adaptor Union ABS Metric Galvanised Malleable Iron Male Thread R PN10

  Datasheet (PDF)

The Georg Fischer ABS adaptor union provides a dependable detachable transition between metric ABS thermoplastic piping systems and metallic equipment or valves with threaded ports. Designed specifically for demanding industrial chilled water and secondary refrigeration installations, this three-piece composite union integrates an ABS metric solvent cement socket bush, a high-strength ABS union nut, a galvanized malleable iron threaded end with taper male thread R, and an EPDM profile gasket. The fitting enables swift mechanical dismantling and reassembly of pipe sections, ensuring full maintenance access to pumps, flow meters, heat exchangers, and control valves without cutting into installed plastic pipework.

Manufactured by Georg Fischer to precise dimensional tolerances, this union is rated for a nominal operating pressure of PN10 (10 bar) at a reference temperature of 20 degrees C. The metric socket end accommodates ABS pipe diameters from 20 mm up to 63 mm, utilizing Tangit ABS solvent cement for a homogeneous joint. On the metallic side, the male taper thread R (from 1/2 inch to 2 inches) creates a secure connection into female threaded metal fittings and equipment bodies. The robust malleable iron construction with hot-dip galvanized surface protection delivers high mechanical strength against assembly stresses and vibrations, while the thermoplastic components eliminate galvanic corrosion across the plastic distribution lines.

Acrylonitrile Butadiene Styrene (ABS) offers exceptional structural ductility, high impact resistance at low temperatures, and solid chemical resistance against industrial water, glycol solutions, and cooling brines. The EPDM sealing gasket ensures long-term leak tightness under alternating thermal cycles and continuous vibration. This makes the adaptor union fitting ideal for chilled water circuits, HVAC cooling loops, marine pipework, and industrial water treatment installations.
