Precision Extreme-Pressure Stainless Steel Threaded Pipe Fittings
Made to tighter tolerances than other stainless steel pipe fittings, these are also known as instrumentation fittings. The male threads are rolled for extra strength in extreme-pressure applications. Fittings are commonly used to connect equipment in gas and hydraulic fluid lines. They are 316 stainless steel for excellent corrosion resistance. Inline tees are also known as branch tees. Right-angle tees are also known as run tees.
