❓ Frequently Asked Questions
What are the different material grades (W1-W5)?
W1 refers to all-zinc plated steel. W2 uses a stainless steel band and housing with a zinc-plated screw. W4 and W5 are high-grade stainless steel (304SS and 316SS) for maximum corrosion resistance in marine and industrial environments.
What is the advantage of the perforated band design?
The perforated band (American type) allows for a flexible and strong interlock with the worm gear screw, providing a reliable and adjustable seal for various hose diameters.
What is the recommended installation torque?
For W1 materials, the suggested torque is 3.8Nm. For stainless steel grades (W2, W4, W5), the recommended installation torque is 6Nm to ensure a leak-proof connection without damaging the hose.
What are the typical applications for these clamps?
These clamps are widely used in automotive parts, telescope adjustment, marine hose connections, and industrial pipe tubing where a secure, adjustable fastening is required.
Are these clamps certified for quality?
Yes, our manufacturing processes are certified under ISO, TUV, BSCI, and IATF standards, ensuring consistent quality and performance for global industrial requirements.
How do I choose the correct size?
Measure the outer diameter of your hose when it is connected to the fitting. Choose a clamp size range (e.g., 13-23mm) where your measurement falls comfortably in the middle of the range.
