SIGMA Waterworks is pleased to highlight our large inventory of domestic and imported fittings in sizes from 2” to 64”. SIGMA’s C153 ductile iron mechanical joint and flanged fittings are manufactured in accordance with ANSI/AWWA C153/A21.53 and they uphold our rigorous quality assurance standards. They meet required rated water working pressure with a 2:1 safety factor, and are heat coded for traceability and verification of metallurgical properties. SIGMA fittings are certified to NSF/ANSI/CAN 61 and 372, and select sizes are also UL Listed and FM Approved for fire protection service.
We offer a full range of coatings and linings to suit your specifications and applications, and our service and engineering teams are available to provide product and installation support.
SIGMA’s distribution network ensures timely delivery across North America. When customers also source restraints, field essentials, and meter enclosure products from SIGMA, they gain efficiency and savings: one purchase order, one vendor, and reduced freight costs.
