Additive Line / HI.PR/28TC/Polyhose
This high-pressure polyhose is engineered to withstand continuous flow, temperature variations, and crystallization risks associated with urea handling. Its reinforced construction prevents swelling, cracking, and leakage, ensuring consistent dosing pressure for stable SCR function. The hose maintains flexibility while offering strong resistance to chemicals, abrasion, and vibration during heavy-duty operation.
By providing reliable urea transfer, the additive line supports accurate dosing, effective NOx reduction, and long-term emission compliance. It also prevents contamination, pressure loss, and dosing faults, ensuring smooth SCR operation in commercial diesel vehicles.
Key Features
- High-pressure polyhose for urea/AdBlue transfer
- Reinforced design prevents swelling and leakage
- Resistant to chemicals, heat, abrasion, and vibration
- Ensures stable pressure for SCR dosing
- Suitable for heavy-duty commercial diesel engines
