The Manufacturers Standardization Society (MSS) of the Valve and Fittings Industry announces that SP-111-2020, Gray-Iron, and Ductile-Iron Tapping Sleeves, has been revised and published by MSS.
Standard Practice (SP)-111 has served as an industry norm for over 28 years; covering the performance and design requirements of gray-iron or ductile-iron tapping sleeves used in water and sewage systems.
