SMS Seals (SS 1149)
SMS seals are square section rings typically used in SMS (Swedish Metric Standard) sanitary unions. The union assembly consists of an internally threaded nut, liner and externally threaded male part. The elastomer SMS seal is captive, located in a groove within the male part of the union assembly. This design provides a smooth, crevice-free internal bore. SMS seals are ideal for applications that do not demand constant disassembly of pipes/hoses.
