90° reduced tee PVDF

  Datasheet (PDF)

The Georg Fischer SYGEF Standard 90-degree reduced tee in PVDF is engineered for high-integrity branch connections in demanding industrial fluid distribution networks and ultra-pure process piping systems. Manufactured by Georg Fischer from high-grade, unpigmented polyvinylidene fluoride, the fitting delivers outstanding chemical resistance against aggressive acids, inorganic salts, aliphatic hydrocarbons, and oxidizing media, while retaining superior structural stability across an operating temperature range from -20 degrees Celsius to +140 degrees Celsius. Operating reliably at a nominal pressure rating of PN10 (SDR33), the reducing tee is optimized for butt fusion jointing, supporting both contactless infrared (IR Plus) welding compliant with DVS 2207-6 and conventional butt fusion according to DVS 2207-15. Spigot dimensions cater to main run diameters from d160 mm to d225 mm with reduced branch transitions to d90 mm, d110 mm, and d160 mm, ensuring seamless geometric alignment, laminar transition profiles, and minimized hydraulic pressure drop. The smooth internal bore with a surface roughness finish of Ra less than or equal to 0.5 micrometers prevents particle entrapment, scaling, and biofilm accumulation, making the fitting ideal for pharmaceutical purified water (PW), deionized (DI) water loops, and clean chemical dosing lines. With physiological non-toxicity verified according to FDA 21 CFR 177.2510 and USP Class VI, the tee withstands repeated sanitization procedures using clean steam, hot water, ozone, and chemical sterilants. Permanent molded embossing guarantees comprehensive batch-level traceability by detailing the manufacturer brand name, material type, nominal dimensions, pressure rating, and production lot number.
