Reducing bush long pattern PVC-C metric

  Datasheet (PDF)

Manufactured by Georg Fischer, this metric long pattern reducing bush in PVC-C is engineered for high-integrity diameter transitions within industrial thermoplastic piping networks. Unlike compact short-pattern fittings, the extended cylindrical spigot and socket geometry delivers an optimized hydraulic profile, minimizing flow turbulence and pressure losses across fluid circuits. Designed for solvent cement jointing, it establishes permanent, homogeneous, and leak-tight connections across metric pipe dimensions ranging from 32 x 20 mm up to 90 x 63 mm. With a nominal operating pressure rating of PN16 at 20 degrees Celsius, this fitting maintains continuous reliability under demanding hydrostatic loads.

Produced from high-grade post-chlorinated polyvinyl chloride (PVC-C) in agate grey RAL 7038, the fitting demonstrates superior mechanical rigidity and high-temperature capability up to 80 degrees Celsius under pressure. Compared to conventional PVC-U, PVC-C provides elevated resistance against aggressive industrial chemicals, including concentrated inorganic acids, alkalis, and salts such as sulfuric acid, hydrochloric acid, and caustic soda. The compound is flame retardant and exhibits excellent dimensional stability in elevated thermal regimes, preventing thermal deformation and stress relaxation over long operational lifespans.

Manufactured in full compliance with ISO 15493, ISO 727, and DIN 8079/8080 dimensional standards, the fitting ensures precise joint fitment and consistent bonding with industrial PVC-C solvent cements. Typical applications include chemical processing, industrial wastewater treatment, demineralized water distribution, electroplating plants, and hazardous chemical dosing lines.
