Stainless Steel Threaded Fittings

Stainless steel threaded fittings are used to connect steel pipes. Tapered threads are cut into the end of the pipe, sealant is applied in the form of thread-sealing compound or thread seal tape (which is also known as PTFE or Teflon tape), and a pipe wrench is used to thread the pipe into a threaded fitting.

What are stainless steel threaded fittings used for?

Stainless steel threaded fittings are often used in buildings to convey natural gas or propane fuel, or in plumbing systems. They are a popular choice in fire sprinkler systems due to their resistance to mechanical damage and intense heat.

Threaded fittings made with stainless steel take advantage of the metal’s strength, resistance to corrosion and ease of cleaning.

Types of stainless steel threaded fittings

Different types of stainless steel threaded fittings include bulkhead adapters (used to connect tubing or piping of different sizes and configurations through a panel), nipples (used to connect two other fittings), elbows (used to connect pipes at curved angles), and tees (T-shaped fittings that accommodate three pipes).
