Product Overview – Turbo V-Band Clamp 3.21 in
The OTX-4VC0321A V-band clamp (3.21 in (81.5 mm)) is engineered for turbocharger joints that see high heat, vibration and frequent service, and it is compatible with Peterbilt 389.
A turbo V-band clamp locks the turbocharger housing to the exhaust or downpipe flange, where heat cycles and engine vibration demand a tight, uniform clamping load.
For fitment checks, note a 0.75 in band width, a 0.05 in insert thickness, an insert depth of 0.141 in; compare these with your original clamp before ordering.
It cross-references to 3 OEM part numbers, including Mack 1ME268M, Mack 20592787, Volvo 20592787, and 3 aftermarket numbers, so you can match the exact clamp you are replacing.
Tip: tighten evenly to the recommended torque and re-check after the first heat cycle.
