The Roth 2350000026 is a 2 inch male by 3/8 inch compression duplex bushing designed for use with Roth oil storage tank systems. This fitting installs directly into the Roth tank opening and is secured in place by the Roth tank cap nut, creating a reliable and leak-resistant connection point at the top of the tank. Duplex bushings like this one serve a critical role in oil storage and fuel delivery systems by allowing two separate connections to pass through a single tank fitting. This design reduces the number of openings needed in the tank lid, which helps minimize potential leak points and simplifies the overall installation. The 2 inch male thread connects to the standard Roth tank port, while the 3/8 inch compression fitting accommodates copper or compatible tubing used for supply and return lines in residential heating systems. Plumbers, oil burner technicians, and heating system installers rely on fittings like the Roth 2350000026 when servicing or replacing oil tanks. The compression fitting end makes for a clean, tool-accessible connection that does not require soldering, which speeds up installation time in tight mechanical rooms or utility spaces. This bushing is built to work within the Roth double-wall tank system, which is widely used in residential and light commercial heating oil storage applications. Using the correct manufacturer-matched fitting helps maintain the integrity of the tank assembly and supports compliance with local fuel storage codes. When replacing or upgrading an oil tank, sourcing the proper Roth fittings ensures a secure, compatible fit with the tank cap nut and opening threads. This part is a straightforward replacement component for any technician working within the Roth tank ecosystem.
The Roth 2350000026 duplex bushing provides a dual-connection solution for Roth oil storage tank systems, combining a 2 inch male thread with a 3/8 inch compression fitting for reliable, leak-resistant fuel line installations.
