UPVC SWR Pipes and Fittings Salient Feature of Karan UPVC SWR Pipes & Fittings Weather resistant upto -5° to 70° ± 2°C Thermal Stability - Proper care has been taken of thermal gap and expansion. There is no problem of clogging & choking up of drain because of smooth inner surface. Cleaning is easier as the system consists of threaded door cap. Fire resistant and self-extinguishing. It is non-corrosive and immune to galvanic or electrolyte erosion. At the compounding stage special treatment is done to make it Rodent Repellent. It last long as more than life time. C
