Sudarshan Electrofusion Fittings are meticulously manufactured in-house to meet both national (ISO: 4427) and international standards (EN1555 part 3, EN12201 part 3). Designed with SDR 11 and SDR 13.6 ratings, these fittings ensure optimal jointing for drinking water, drainage, and gas pipelines. The Electrofusion process involves inserting pipes into the fittings, applying an electric current to seamlessly fuse the inner and outer surfaces. Each fitting is equipped with barcodes for precise heat and timing control, ensuring a secure and reliable connection every time.
