NORRES CONNECT 245 VAC-TRUCK
Heavy-duty tapered flange coupling for vacuum and suction vehicles – robust, tight and reusable
The NORRES CONNECT 245 VAC-TRUCK is a tapered flange coupling system designed for suction and vacuum vehicles such as vacuum excavators, sludge collectors and sweepers. It is built for heavy-duty operation, frequent assembly and disassembly, and high mechanical stress. Available in standard, soft, reinforced and pre-fitted versions – the latter providing a gas- and liquid-tight moulded connection between flange and hose.
Applications
CONNECT 245 VAC-TRUCK is used for conveying and suction of solid and liquid materials in:
- Suction and vacuum vehicles
- Municipal sweepers and cleaning trucks
- Sludge collectors and vacuum excavators
Properties and construction
- Tapered flange coupling for quick and secure mounting on vacuum hoses.
- Gas- and liquid-tight when used in pre-fitted version.
- Available in different hardness grades – standard (80 Sh D), soft (85 Sh A) and reinforced (85 Sh D).
- Highly abrasion-resistant and hydrolysis-resistant Pre-PUR® wall.
- Resistant to oils, gasoline and many chemicals.
- Complies with RoHS and REACH directives.
- Temperature range –40 °C to +90 °C.
Materials
- Wall: Ether-based Pre-PUR® polyurethane.
- Flange: Reinforced tapered black flange with steel insert (depending on version).
- Clamp: Quick-release or reinforced clamp (optional).
Technical note
For vertical installation, always secure the flange and hose with additional mounting or safety chains, as material weight may generate shear forces. The CONNECT 245 VAC-TRUCK is designed to maintain tightness under vacuum and impact stress but requires proper selection of hardness and reinforcement. The reinforced version is recommended for continuous use in high-abrasion vacuum and suction systems.
Recommended accessories
- CLAMP 211 / 213 – reinforced T-bolt clamps for vacuum hoses.
- CONNECT 244 FOOD – food-grade flange connection for Pre-PUR® hoses.
- CONNECT 245 – Tri-Clamp coupling for process and industrial hoses.
