Potterton Brass Nipple G1.1/4 X G1.1/4 7610402

The Potterton brass nipple (part number 7610402) is a threaded brass fitting with a G1.1/4 connection at each end. It is used on Potterton Commercial Sirius 2 FS Cascade boiler installations to join the two threaded ports it matches. Brass construction gives it the corrosion resistance expected at a water or heating circuit joint.

• Weeping or dripping at the threaded joint, with water tracking down the pipework
• Visible corrosion, green discolouration or heavy scale on the brass body
• Damaged or flattened threads that will not seal cleanly or take a spanner without slipping
• Water staining or mineral deposits around the connection after the boiler has been running

• Confirm the thread size required is G1.1/4 at both ends, as thread size is the primary fitment check
• Check the appliance model against the fit list above before ordering
• Inspect the mating threads on the appliance connection for damage, as a worn port will not seal against a new nipple
• Have suitable sealing material and the correct spanner size available before starting the work
