316 Stainless Pipe Fittings - Class 150 - 202

We offer two types of stainless steel pipe fittings. Our suffix SP (SP114 heavy industrial grade) are designed to the dimensions and pressures of ANSI/MSS SP-114 Class 150 (similar to ANSI B16.3 for malleable iron) and are a more robust fitting designed for commercial and industrial piping systems in chemical plants, pulp & paper, petroleum, steam systems, and more critical industrial processes that are subject to various stressors. Our SS common/standard series are dimensionally smaller with less material for a lower price point, and similar to other brands on the market.
