Abstract: Various embodiments of a longitudinal fitting or other fluid conduit for a piping system are provided. The fitting can comprise a body including a first portion, a second portion, and a barrier between the first and second portions. The first portion can include a first inner surface that defines a first opening that is sized and configured to receive a first piping system component. In various embodiments, the barrier can be positioned between the first inner surface and a second inner surface of the second portion; the barrier can at least partially define a reservoir. When the first piping system component is secured to the fitting by a securing liquid, such as solvent cement, the barrier and/or reservoir can resist the liquid from reaching the second inner surface, thereby reducing the likelihood that the second inner surface will become damaged or otherwise compromised by chemically reacting with the securing liquid.

Abstract: Various embodiments of a fitting or other fluid conduit for a piping system are provided. In at least one embodiment, a fitting comprises a body including a first portion and a second portion, and a barrier positioned between the first and second portions. In various embodiments, the first portion includes a first inner surface that defines a first opening that is sized and configured to receive a first piping system component. The first piping system component may be secured to the first portion by a securing liquid, such as a solvent cement. Further, in various embodiments, the second portion includes a second inner surface defining a second opening that is sized and configured to receive a second piping system component. In various embodiments, the barrier, such as a lip, for example, may be positioned between the first inner surface and the second inner surface, and the barrier may at least partially define a reservoir with an open side facing the first portion.
