Mercedes Sprinter DEF Dosing Valve Injector Clamp – Genuine OEM | #0009951133

DESCRIPTION:

The DEF injector clamp is the retention hardware that locks the AdBlue dosing valve securely in place in the exhaust. It's a small part with an important job — without it properly seated, the DEF nozzle can't maintain its position or seal, which affects injection accuracy and can lead to exhaust leaks at the injection point. This is the genuine Mercedes-Benz OEM replacement clamp, a must-have any time the DEF dosing valve or injection nozzle is being serviced or replaced.

What This Part Does

The DEF injector clamp secures the dosing valve (injection nozzle) to the exhaust pipe at the SCR injection point. It holds the nozzle at the correct angle and depth for precise urea delivery into the exhaust stream. Any time the dosing valve is removed for cleaning, inspection, or replacement, this clamp should be inspected and replaced if deformed, corroded, or no longer seating properly.

When to Replace It

Replace this clamp any time the DEF dosing valve is removed or replaced. Reusing a deformed or corroded clamp risks an improper seal at the injection point — leading to exhaust leaks, incorrect nozzle positioning, and DEF system fault codes. It's an inexpensive item that should always be replaced as a matter of course during any DEF injector service.
