The adapter socket nipple d90/110 × 2 1/2″ is a PVC fitting used as a transition from smooth socket pipe with a diameter of 90 or 110 mm to a 2 1/2″ BSP male thread.
The dual diameter marking (d90/110) indicates compatibility with both nominal sizes according to the pipe’s type designation, which extends the usability of the part across various installations.
The PVC material is resistant to corrosion, chlorinated water and pH adjustment products, so the nipple performs flawlessly in the permanently wet environment of a pool installation.
The connection to the pipe is made by gluing, while the threaded connection to the fitting uses a standard 2 1/2″ BSP thread with Teflon tape.
