Dinex Leak-Tight Decoupling Application Examples

Dinex Leak-Tight Decoupling elements (DLTD) offer 100% leak tightness and thermal insulation to improve catalyst performance, making it suitable for on-road vehicles such as buses, LCVs, and long-haul trucks, as well as off-road applications like construction equipment and mining trucks. Its ability to compensate for various movements, including torsion, ensures effectiveness in demanding environments. Furthermore, DLTD’s adaptability positions it as a viable component for upcoming technologies like H2 ICE and fuel cells.

On-Road - Light, Medium and Heavy Commercial

Application demands

  • Leakage tightness
  • Heat preservation (for efficient catalyst performance)
  • Long mileage

Why Dinex DLTD

  • Fully leak-tight component tested at 0,5 bar.
  • Thermal insulation eliminates cold spots in the system, which results in more stable temperature in the system.
  • Deposit-free design prevents decoupling element from breakage due to lock clogging.
On Road

Off-Road - Construction & Agriculture

Application demands
