NORRES CONNECT 244
Two-part loose flange with steel core – for NORRES hoses and DIN 2632/2633 flange systems
NORRES CONNECT 244 is a robust two-part loose flange designed for connecting spiral hoses to pipe systems and mating flanges according to DIN 2632/2633 and bolt pattern DIN-EN 1092-1. It combines high mechanical strength with excellent chemical resistance, making it ideal for industrial extraction, process and transport systems. Available as a reusable threaded version or as a pre-fitted gas- and liquid-tight version.
Properties and construction
- Easy and quick installation – reusable threaded version.
- Gas- and liquid-tight in the pre-fitted version.
- Two-part construction with polypropylene (PP) coated steel core flange.
- Inner wall made of premium ether-polyurethane (Pre-PUR®) for superior abrasion resistance.
- Resistant to oil, gasoline, microbes and chemicals.
- Temperature range: –40 °C to +90 °C.
- Complies with RoHS directive and REACH regulation.
Applications
CONNECT 244 is used in material conveying, ventilation, vacuum and process systems where a strong and tight flange connection is required between hose and mating flange. Compatible with DIN flange systems and NORRES hose series such as AIRDUC®, PROTAPE® and CP.
Technical note
In ATEX installations, the flange, hose and coupling must all form part of the same equipotential bonding system. The steel-reinforced core of CONNECT 244 ensures electrical continuity and makes it suitable for antistatic and conductive hoses. Always select the correct flange diameter and bolt pattern according to DIN-EN 1092-1.
Recommended accessories
- CLAMP 211 / 212 / 213 – clamps for fastening spiral and smooth hoses.
- CONNECT 270 – 271 – stainless couplings for process and food applications.
