How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Titanium Threaded Pipe Fittings

Titanium has similar strength to steel, but is approximately 40% lighter. It has better corrosion resistance than most stainless steel alloys and can handle corrosive substances, such as salt water and acids.

Titanium Helical Inserts

These inserts have a high strength-to-weight ratio and resist acids and salt water better than nickel alloy and stainless steel inserts. Also known as Heli-Coil inserts, they have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw. Installation requires a drill bit, a helical insert tap, an installation tool, and a prong break-off tool.
