SIGMA has expanded our inventory of large-sized fittings to meet the needs of the current marketplace. Due to the nationwide increase in public works projects, there is an uptick in demand for large-sized fittings. Our current inventory of fittings can meet the needs of large-size applications, and we are well stocked with fittings in the 54-64” range.
SIGMA’s C153 Ductile Iron Mechanical Joint Fittings and C153 Ductile Iron Flanged Fittings are produced in accordance with ANSI/AWWA requirements and are hydrostatically tested to comply with SIGMA’s stringent quality management standards. These fittings are rated for 150 PSI water working pressure, will meet safety factor of 2:1, and are heat coded to ensure traceability and verification of the metallurgical properties per SIGMA’s rigorous quality assurance protocols. They are certified to NSF61 standard, including Annex G & 372.
SIGMA pioneered this product line over a decade ago and has continued to be a leader in the sector ever since. In 2012, the company received an inquiry for 54” MJ Bell fittings, and, to meet the customer request, developed the product. The large-sized fittings were well received in the marketplace, and as a result, SIGMA identified a need to expand the offering. Subsequently, SIGMA’s engineering team developed 60” and 64” MJ fittings, and in 2015, AWWA approached SIGMA with an invitation to include the large-sized fittings in their specifications. In response, SIGMA submitted all product and QA details for review, and now large-sized fittings are included in the respective AWWA Standards.
