⚙️ Key Features

• 0.029 kg
• One application on the TWD series
• No published thread size — order by part number
• One of several single-application TWD fittings in this group

🔌 Function

Forms a threaded union between a line and its port so fluid can pass from one to the other without leaking.

⚠️ Common Signs of Failure

• Weeping, misting or dripping at the union
• Thread damaged, cross-started or corroded
• Sealing taper or cone face nicked or scored
• Nipple cracked or split at the hex

🛠️ 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
