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

HUPLONG INDUSTRIES (M) SDN BHD supplies genuine NORRES SIL 391 TWO hoses for customers throughout Malaysia requiring a double-layer silicone hose for flexible ducting of hot and cold gases.

SIL 391 TWO is a silicone hose with a double-layer construction. Its design includes a spring steel wire integrated in the hose wall, fabric-reinforced tape, a silicone-coated glass-fabric wall and reinforcing cords made of interwoven yarns.

NORRES officially lists SIL 391 TWO as fibre reinforced and with very good heat resistance. The hose conforms to the RoHS guideline, and the official temperature range is -70°C to 260°C, with short-time use up to 280°C.

Official NORRES applications include granulate and plastic dryers, hot-air dryers, film blowing machines with cooling air at the extrusion tool, air supply for UV dryers and IR dryers, clean-room ventilation and semiconductor production machines.

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