Full model list at the end of this description.

⚙️ Key Features

• 139 published applications across D and MD series
• Supersedes 1304930, formerly a t-pipe
• Published weight of 0.001 kg is not credible for this part

🔌 Function

Joins two cooling hoses or a hose to a pipe, carrying coolant across the joint without leaking.

⚠️ Common Signs of Failure

• Coolant loss or crusted salt trails at the joint
• Coupling corroded through or cracked
• Barb or spigot pitted so the hose no longer seals
• Hose ends split where they pass over the coupling
• Coolant level dropping with no other visible cause

🛠️ Service Notes

• Check availability before planning the job and be ready to renew the whole hose run
• The number it replaces was listed as a t-pipe, so a branched fitting may be what the engine actually carries
• Fit new hoses and clamps at the same time
