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

HUPLONG INDUSTRIES (M) SDN BHD supplies genuine NORRES CP PTFE-INOX 475 EC hose for flexible ducting of hot and cold gases, as well as dust, powder and fibres. NORRES also lists this model for extraction arm installations and explosion hazard area applications.

NORRES CP PTFE-INOX 475 EC is an electrically conductive clamp profile hose, also known as a clip hose. Its official construction includes an all-stainless steel INOX clamp profile supporting spiral and a PTFE coated glass fabric wall. The external clamp profile provides abrasion protection and securely clamps the hose wall within the profile.

The hose is highly flexible and compressible at a ratio of 4:1. NORRES specifies very good heat resistance, anti-adhesive properties, good resistance to alkalis and acids, and extremely good resistance to chemicals. The official surface resistance of the PTFE film is below 10⁶ Ω.

NORRES specifies a temperature range from -150°C to +250°C, with short-time temperature resistance up to +270°C. NORRES also states that the hose is in accordance with ATEX 2014/34/EU and German TRGS 727 for aspiration of combustible dusts in Zone 22 inside the hose, use in Zone 1 and Zone 2 for gases, and use in Zone 0 for gases. The complete system design, earthing arrangement and installation requirements must be checked before selection.

The permitted pressure, vacuum and bending radius values vary by hose size and must be checked against the official technical table before use.

Our team can assist customers throughout Malaysia with NORRES hose selection based on hose diameter, conveyed material, operating temperature, airflow, vacuum condition, installation length and quantity requirement.
