• 19 applications across TAD and TWD engines
• Distinguished from 78509620 only by bore size

🔌 Function

Clamps around a pipe or hose of matching diameter and holds it firmly at its mounting point.

⚠️ Common Signs of Failure

• Pipe or hose moving in the block and chafing
• Block cracked or split at the clamping face
• Wear or a polished mark where the pipe has been working
• Fastener loose or missing at the mounting

🛠️ Service Notes

• Measure the pipe before ordering, as 78509620 is the 12.7 mm version and both weigh 0.017 kg, so weight is no guide at all
• Do not clamp a block onto an undersized pipe, as it will not grip and the pipe will chafe through

📦 Condition
