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.
Female x male 90° elbow adapters are also known as street elbows. Inline tees are also known as branch tees. Right-angle tees are also known as run tees.

Also known as feedthroughs, these fittings transfer liquids, cryogenic liquids, or gasses into high-vacuum chambers for coating, cooling, and leak-testing applications without losing vacuum pressure. Consisting of high-vacuum fittings, metal tubing, and Yor-lok tube fittings, these complete assemblies come ready to install. The quick-clamp (KF) or flanged (CF) high-vacuum fittings form a tight seal on chamber walls. On each end, the Yor-lok fittings include a nut and two sleeves that grip your system’s stainless steel tubing for a leak- and gas-tight connection. The entire assembly is stainless steel so it resists rusting. Not for use in pressure applications.
Quick-clamp fittings meet ISO (International Standards Organization) 2861, which specifies the dimensions of quick-clamp high-vacuum fittings, clamps, and rings to ensure vacuum tightness. These fittings require a clamp and ring (each sold separately) to complete the connection.
Flanged fittings require a gasket and bolt kit (each sold separately) to complete the connection.

Pipeline Fluid Blockers
Also known as paddle blinds, these fit between two flanges to temporarily block the flow while you work downstream.
304 stainless steel blinds are more corrosion resistant than steel blinds.
