PipingNow stocks 150# stainless steel pipe fittings in 304 and 316 stainless, with threaded and socket weld options available across common fitting types and sizes. These fittings are used in stainless piping systems where corrosion resistance, strength, and consistent fit-up matter.
Available options include 45-degree elbows, 90-degree elbows, street elbows, tees, crosses, caps, couplings, reducing couplings, half couplings, hex bushings, hex plugs, square plugs, locknuts, and unions. Sizes range from 1/8" through 10", depending on fitting type, material, and end style.
Threaded and Socket Weld Stainless Fittings
Threaded stainless steel fittings are commonly used for mechanical connections in pipe systems that may require future service or replacement. Socket weld stainless fittings are used for welded connections where a stronger, permanent joint is preferred.
304 and 316 Stainless Steel
304 stainless steel is a solid choice for general-purpose corrosion resistance, while 316 stainless steel is commonly specified for more corrosive environments involving moisture, chemicals, washdown areas, marine exposure, or outdoor service.
Class 150 Stainless Steel Pipe Fittings
These 150# / 150 lb stainless steel fittings are built for moderate-pressure piping applications in water, air, gas, HVAC, marine, food and beverage, processing, and general industrial systems. Many of the threaded options are cast stainless steel pipe fittings used throughout standard stainless pipe assemblies.
150# Stainless Steel Fitting Types
PipingNow carries a broad range of class 150 stainless fittings, including elbows, tees, crosses, couplings, reducing couplings, caps, plugs, bushings, locknuts, half couplings, and unions. Product options include both 304 and 316 stainless steel, with threaded NPT and socket weld end styles available where applicable.
FAQs About 150# Stainless Steel Pipe Fittings
What are 150# stainless steel pipe fittings?
150# stainless steel pipe fittings are class 150 pipe connectors used to join, redirect, reduce, or terminate stainless steel piping systems. They are commonly used in moderate-pressure applications where corrosion resistance and reliable fit-up are important.
What fitting types are available?
Available fitting types include 45-degree elbows, 90-degree elbows, street elbows, tees, crosses, caps, couplings, reducing couplings, half couplings, hex bushings, hex plugs, square plugs, locknuts, and unions.
Are these fittings threaded or socket weld?
This collection includes both threaded NPT stainless fittings and socket weld stainless fittings. Availability depends on the specific fitting type, size, and material grade.
What is the difference between 304 and 316 stainless steel fittings?
304 stainless steel is commonly used for general corrosion resistance. 316 stainless steel provides added resistance in more corrosive environments, including marine exposure, chemical service, washdown areas, outdoor use, and moisture-heavy applications.
What sizes are available?
Sizes range from 1/8" through 10", depending on fitting type, end style, and stainless grade.
Where are 150# stainless steel fittings commonly used?
Common applications include water lines, air systems, gas service, HVAC, marine piping, food and beverage facilities, light process piping, commercial systems, and general industrial stainless pipe assemblies.
