Product Overview – V-Band Clamp 4.94 in
V-Band Clamp 4.94 in (OTX-4VC0494) provides a strong, low-profile joint for exhaust and turbo flanges in heavy-duty diesel applications, with a 4.94 in nominal diameter, and it is compatible with Multiple Mack Applications.
V-band clamps replace bolted flanges with a single-fastener joint that is faster to install and easier to service while keeping an even seal all the way around.
Key dimensions include a 0.75 in band width, a 0.06 in insert thickness, an insert depth of 0.281 in; compare these with your original clamp before ordering.
It cross-references to 4 OEM part numbers, including Mack 25183805, Mack 11 ME29, Mack 48RU2289P1, and 16 aftermarket numbers, so you can match the exact clamp you are replacing.
Tip: always match the clamp size to the outside diameter of the joint, not the pipe or hose inside diameter.
