ХОМУТ Caterpillar 3940001

The Pre Diesel Oxidation Catalyst Clamp fastens the catalyst unit securely to adjoining exhaust components, ensuring a tight and stable connection. The clamp prevents the catalyst housing from shifting and loosening during exhaust flow, maintaining a sealed path for gas treatment. By holding the catalyst firmly, it supports efficient oxidation of exhaust emissions before they reach downstream filters. The clamp also minimizes the impact of vibration, ensuring reliable retention of the catalyst unit. Attributes:• Withstands thermal expansion and contraction.• Minimizes vibration transmission to the diesel oxidation catalyst.• Maintains uniform clamping force.Applications: The Pre Diesel Oxidation Catalyst Clamp is mounted at the joint where the catalyst unit connects to the adjacent components, to provide a secure, sealed joint that maintains structural integrity and leak resistance.
