Full model list at the end of this description.

⚙️ Key Features

• Machined thread and sealing geometry
• Correct flow bore for the cooling circuit
• Designed for the specified seal or thread compound
• Corrosion-resistant coolant-system material
• Pump/housing generation and serial number must match

🔌 Function

Forms a sealed coolant connection between the pump/housing and the adjoining cooling pipe or hose.

⚠️ Common Signs of Failure

• Coolant seepage at the thread or seal
• Corrosion or pitting of the sealing surface
• Cracked or damaged threads
• Restricted flow from deposits
• Hose or pipe misalignment caused by the wrong nipple

🛠️ Service Notes

• Check the bore is clear before fitting — a nipple is often the feed point or restriction for a circuit, and debris left in it will starve whatever it supplies
• On tapered threads use the paste or liquid sealant specified for the fluid concerned, applied a few threads back from the open end; avoid thread tape on fuel and oil lines, where a shed shred travels downstream into filters, pumps and injectors
• Where the nipple seals on a face or against a washer rather than on its thread, fit a new sealing washer instead of curing a weep by overtightening
• Tighten to the figure in the workshop manual for your engine — these are small fittings in castings and are easily stripped, or the surrounding boss cracked
• Support the pipe or hose so it meets the nipple square and without side load, then check the joint at working pressure and temperature
