(304 grade)Application: Automotive / Plumbing / Radiator / Intercooler / Turbo/ Exhaust / Muffler TIPS: Before purchasing, determine whether the clamping range of the hose clamp is suitable for the outer diameter of the tube. After connecting to the joint, the hose will swell to some extent. To select the suitable hose clamp, we suggest that you measure the outer diameter of the hose when the hose is connecting the joint and swelling. If a sleeve is added to the hose, the thickness of the sleeve must also be calculated. Hose clamp size = hose outer diameter + sleeve thickness 2. For example, if the outer diameter of the hose is 32 mm + the thickness of the sleeve is 2mm2=32 mm+4 mm=36 mm, then a hose clamp of 36-39mm specifications should be purchased. To ensure safety and clamping force, it is not recommended to repeatedly disassemble the hose clamps, which may make the thread worn and the screw broken.
