What does TOL stand for?

What does TOL stand for?

• A. Thread - o - let
• B. Thickness Of Length
• C. Tolerance Of Load
• D. Tooling On Lead

Answer: (A)

In piping and welding terminology, TOL stands for Thread-O-Let, a type of branch fitting that provides a threaded outlet off a main line. The name emphasizes two things: the branch is threaded, and the fitting is an O-let, or outlet, off the pipe. This kind of fitting is used when you need a threaded connection for a valve, sensor, or other device off the main run, without performing a weld on that branch. The other options don’t reflect a standard pipe-fitting term, so they don’t describe this concept accurately.
