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

HUPLONG INDUSTRIES (M) SDN BHD supplies genuine NORRES CLAMP 211 T-bolt clamps for customers throughout Malaysia who require a hose connection accessory for heavy-duty hoses with a smooth outer wall.

NORRES CLAMP 211 is a T-bolt clamp designed for attaching heavy-duty hoses with a smooth outer wall. It is not a bridge clamp for externally corrugated spiral hoses. The correct clamp must therefore be selected according to the actual hose outer-wall construction and official NORRES compatibility information.

NORRES officially lists CLAMP 211 as easily and quickly fitted, re-usable and compliant with the RoHS guideline. It is available in W1, W2 and W4 material qualities. The official design includes W1 with galvanised steel clamp strip and screw, W2 with stainless steel 1.4016 / AISI 430 clamp strip and galvanised steel screw, and W4 with stainless steel 1.4301 / AISI 304 clamp strip and screw.

Official NORRES compatible hose series include selected AIRDUC® 355, AIRDUC® 356 and AIRDUC® 357 PLUS models; PROTAPE® 335; selected NORPLAST® hose models; BARDUC® 382; NEO 390 ONE / TWO; and SIL 391 ONE / TWO. Exact hose-model and clamp-size compatibility must be checked before installation.

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. For CLAMP 211 selection, the hose outside diameter, smooth outer-wall construction, required material quality and official clamping range must be confirmed before use.
