What Is a Weldolet?

A Weldolet is a type of "Olet" fitting designed to create a 90° branch connection from a main (header) pipe to a smaller branch pipe. It's butt-welded on both ends (to the run pipe and to the branch).

It's preferred in high-pressure applications due to its smooth flow path and high structural strength.

Specification of MSS SP-97 Weldolet Fittings

An ASTM A694 F65 weldolet is a type of pipe fitting used for creating a branch connection from a main pipe (run pipe) at a 90-degree angle. It is specifically made from forged carbon steel or alloy steel that conforms to the ASTM A694 grade F65 specification.
