Product Overview \u2013 EGR V-Band Clamp 3.21 in<\/h3>\n

The OTX-4VC0321MK V-band clamp (3.21 in (81.5 mm)) is engineered for EGR system joints that see high heat, vibration and frequent service, and it is compatible with Mack Pinnacle Clamp EGR Hot Side Tube.<\/p>\n

EGR joints see constant heat and pressure pulses; this clamp keeps the tube and cooler flanges aligned and sealed, and is quick to remove during EGR service.<\/p>\n

Measured dimensions: a 0.625 in band width, a 0.05 in insert thickness, an insert depth of 0.625 in; compare these with your original clamp before ordering.<\/p>\n

It cross-references to 11 OEM part numbers, including Mack 260GB215, Mack 260GB216, Mack 180GB338M, and 2 aftermarket numbers, so you can match the exact clamp you are replacing.<\/p>\n

Tip: tighten evenly to the recommended torque and re-check after the first heat cycle.<\/p>\n
