What This Product Does

The V-band fastening draws the mating exhaust components together around their joint. Clamping pressure helps hold the connection in position and supports sealing when the adjoining surfaces and associated seal are serviceable.

Functions

• Fastens the mating exhaust connection.
• Helps retain alignment at the joint.
• Applies circumferential pressure to support sealing.
  
  Technical Details

• Component identification: exhaust clamp.
• Fastening type: V-band.
• Supplied diagram quantity: 1 in each referenced assembly.
  
  Symptoms of Fault

• Ticking or blowing audible near the connection.
• Black soot traces surrounding the joint.
• A clamp that cannot tighten correctly.
• Joint movement, uneven positioning or rattles.
• Noticeable exhaust odour around the affected connection.
  
  These signs warrant inspection; they do not establish that the clamp alone is responsible.
  
  Why Replacement Matters

Corrosion, deformation or damaged fastening hardware can reduce the clamp's ability to grip. Renewing a defective clamp helps re-establish the intended fastening arrangement. Before reassembly, examine the adjoining flanges, sealing components and supporting hardware: fitting a new clamp will not correct damaged mating surfaces or poor alignment.
