Fittings

Bushing

Bushings are a type of fitting with external and internal threaded ends, used to connect segments of pipe with different diameters. Sometimes called Reducer Bushings, the larger diameter of the bushing screws into a threaded socket, while the smaller pipe is then screwed into the smaller end of the bushing. They typically have a hexagonal…

Cap

Caps are a type of fitting used to terminate an open end of a pipe. The exterior of an industrial Cap is typically round, but can be square or rectangular. Caps attach to the exterior of a pipe via weld or NPT (nominal pipe thread). While a weld Cap will permanently terminate the line, a…

Coupling

Couplings are used to connect two segments of pipe. Typically, a pipe Coupling will have a threaded ID on either end. Pipes with threaded ends will be screwed into either side of the Coupling to create a longer run of pipe. Couplings can also be Socket Weld, with the square cut pipe ends fitting into…

Cross

A Cross, also known as a four-way fitting, has four ends that are positioned at 90° angles. A Cross can have either one inlet and three outlets, or three inlets and one outlet. The diameters of the outlets and inlets can be the same, but can also be different. James Duva, Inc. supplies both straight…

Elbow

An Elbow is a pipe fitting installed between two lengths of pipe, to change the direction of flow of a piping system. Typically, Elbows are either 90° or 45°, with the inside diameter being a continuous bend. An Elbow with a 180° radius is called a Return. Elbows typically have the same NPS connection on…

Insert

Also called a Reducer Insert, this type of fitting enables standard socket-weld fittings to be used for making any combination of pipe line reductions both quickly and economically. There are two types of Inserts. Type 1 Inserts are forged and machined to accept different size pipes on either end, with the ring surrounding both pipes…

Lateral/Wye

Laterals and Wyes are types of fittings that are similar to Tees. While a Tee has a straight run with a branch at 90°, the Lateral’s branch is at 45°. The Wye has a straight run that terminates in two 45° branches, and when stood vertically, has the appearance of the letter Y. Also like…

Olet

Olets, also known as Branch Fittings, are forged fittings used to create connections from a run pipe to an outlet pipe at either 45 or 90 degrees. The appropriate run size of the Olet is selected based on the NPS of the header pipe. Then, using the ID of the Olet as a template, a…

Plug

A plug is a fitting designed to terminate an opening in a piping system. Plugs are typically threaded, and screw into a port for temporary closure. They are also available for permanently welding into a socket. Plugs can be either standard 150# and SP-114 castings, or forged pressure fittings up to 3000#. Plugs can have…

Reducer

A reducer is a type of pipe fitting used in process piping that reduces the pipe size from a larger bore to a smaller bore (inner diameter). Reducing fittings, which include Concentric, Eccentric and Tee, allow for a change in pipe size to meet flow requirements of a piping system, or adapt to existing piping…
