HUPLONG INDUSTRIES (M) SDN BHD is the authorized distributor of NORRES industrial hoses in Malaysia.

HUPLONG supplies genuine NORRES hoses for automotive-industry applications to customers throughout Malaysia. The current range includes polyurethane hoses for industrial robots and welding equipment, rubber hoses for vehicle air-brake systems and EPDM hoses for hot-water and cooling-water circulation.

Hoses for the Automotive Industry

Automotive Hose Applications

NORRES presents an initial selection of hoses for use in automotive-industry systems. Depending on the individual hose model, the listed applications include industrial robots, welding robots, welding guns, vehicle air-brake systems and automotive cooling-water or hot-water circulation.

The current range covers the routing of gases, liquids and other suitable media. Each hose has a different material, reinforcement system, pressure rating, temperature range and resistance profile. Product selection must therefore be based on the exact medium, working pressure, operating temperature, movement and installation requirements.

Industrial Robot and Welding Robot Hose

NORFLEX® PUR 441 ROBOTIC is an abrasion-resistant polyurethane hose and fabric-reinforced high-pressure hose developed for industrial robots. NORRES identifies it for applications involving industrial robots, robotic equipment, welding equipment, welding robots and welding guns.

The hose can be used in robot dresspacks for routing media such as water and air. Its fabric-reinforced construction helps it withstand pressure while retaining the flexibility required for moving robotic systems.

NORRES identifies NORFLEX® PUR 441 ROBOTIC as highly flexible, highly abrasion resistant and crush resistant. It also provides good resistance to oil, gasoline and chemicals and has a smooth interior and exterior.

According to NORRES, the hose is made from special premium polyurethane and is silicone-free. It is also identified as resistant to welding spots or welding sparks for the stated industrial robot and welding-equipment applications.

Air-Brake Hose for Trucks and Lorries

3215 AIRBRAKE is a rubber air-brake hose intended for use in air-brake systems and other compressed-air systems in trucks and lorries.

The hose has an EPDM inner tube, an EPDM outer layer and textile reinforcement. Its inner tube and outer surface are smooth. NORRES states a burst pressure of 25 bar and identifies the hose according to EN ISO 1307:2008 and DIN 74310:1993.

The current article variants have an operating pressure of 10 bar at 20°C. Final selection must be based on the required internal diameter, system pressure, bending radius and applicable vehicle or air-brake requirements.

Automotive Cooling-Water Hose

3100 RADIACORD® is a cooling-water hose suitable for hot-water and cooling-water applications. NORRES states that it is suitable for the most common cooling liquids.

The hose is constructed with an EPDM inner tube, an EPDM outer layer and textile plies. It is identified according to EN ISO 1307:2008.

The current article variants have an operating pressure of 6 bar at 20°C. Customers should confirm the cooling liquid, maximum operating temperature, internal diameter and required working pressure before selecting the hose.

Operating Temperature Ranges

NORRES states the following temperature ranges for the three products currently displayed in the automotive-industry application section:

• NORFLEX® PUR 441 ROBOTIC: −35°C to 80°C
• 3215 AIRBRAKE: −40°C to 70°C
• 3100 RADIACORD®: −30°C to 100°C

The temperature range alone is not sufficient for hose selection. Working pressure, conveyed medium, hose movement, external abrasion, bending radius and installation conditions must also be checked.

Abrasion Resistance and Flexibility

NORFLEX® PUR 441 ROBOTIC is specifically designed for moving robotic systems. NORRES identifies it as highly flexible, highly abrasion resistant and crush resistant, making it suitable for applications where the hose repeatedly moves with an industrial robot.

Its smooth inner and outer surfaces can support media routing and installation within a robot dresspack. The hose is available in different standard colours, allowing different media lines or robot circuits to be visually distinguished where required.

Resistance to Oil Gasoline and Chemicals

NORRES states that NORFLEX® PUR 441 ROBOTIC provides good resistance to oil, gasoline and chemicals. The exact resistance to a particular substance must still be checked against its concentration, temperature, exposure duration and operating conditions.

General chemical resistance must not be treated as confirmation that the hose is suitable for every automotive fluid or chemical. Customers should verify chemical compatibility before use.

Product Construction and Material Differences

The hoses presented in this automotive range are not technically interchangeable:

• NORFLEX® PUR 441 ROBOTIC: fabric-reinforced special premium polyurethane hose for moving industrial robots and welding equipment.
• 3215 AIRBRAKE: EPDM rubber hose with textile plies for vehicle air-brake and compressed-air systems.
• 3100 RADIACORD®: EPDM hose with textile plies for hot-water and cooling-water circulation.

A hose intended for cooling water must not automatically be used for an air-brake system, and an air-brake hose must not automatically be used as a robotic media-routing hose. The exact product must be selected according to its official application and technical data.

NORFLEX® PUR 401 WELDING Website Status

The current NORRES automotive-industry page still refers to NORFLEX® PUR 401 WELDING in its application information, frequently asked questions and flame-retardant standard section.

NORRES describes it as a special polyurethane hose for routing media such as air or water in industrial robots. The application page states that it is silicone-free, highly flexible, very abrasion resistant, crush resistant and resistant to oil, gasoline and chemicals.

NORRES also states that NORFLEX® PUR 401 WELDING contains a flame-retardant additive and is flame-retardant according to UL94-V0/V2.

However, this model is not currently displayed in the automotive-industry product list, and a current individual product page could not be confirmed. It has therefore not been included in the current clickable product range above. Its current availability and technical documentation should be confirmed directly before it is offered for a new application.
