Outlet Fittings
What are branch connections (or pipe branch outlet fittings aka “Olets”)? Olet fittings are a family of forged products used to make 45 or 90 degrees integrally reinforced branch connections (deviations) from a run pipe (also called, header pipe) to a branch pipe (outlet pipe). The common types of branch fittings are Weldolet, Thredolet, Sockolet, Latrolet, Elbolet, Nipolet, Sweepolet. MSS-SP 97 is the key specification covering reinforced branch connections, introduced by Bonney Forge in the piping market more than 70 years ago.
Pipe branch fittings are used to create integrally reinforced connections from a run pipe (header pipe) to an outlet pipe, at 45 or 90 degrees, alternative to connections made with butt weld tees, reinforcing pads and saddles. This type of forged fittings is otherwise called “branch connections”, or “branch fittings”, or “pipe branch outlet fittings” or, simply, “Olets”.
