❓ Frequently Asked Questions
Q1: What are the benefits of non-perforated bands and rolled edges?
The non-perforated band and rolled edges eliminate sharp edges and holes that can cut or tear hoses. This design significantly extends the service life of rubber and plastic tubing by preventing damage during installation and operation.
Q2: Which material options (W1, W2, W4) should I choose?
W1 (galvanized steel) is ideal for general, low-moisture applications. W2 (430 stainless steel band + zinc-plated screw) offers moderate corrosion resistance. W4 (304/316 full stainless steel) is recommended for highly corrosive, marine, chemical, or outdoor environments.
Q3: What standard do these German-type hose clamps comply with?
These hose clamps are manufactured in strict compliance with the DIN 3017 standard, ensuring reliable quality, precise dimensions, and consistent clamping performance.
Q4: Are custom clamping ranges and OEM services available?
Yes, we provide custom clamping ranges from 8mm up to 240mm. We also offer OEM/ODM services, including custom logo marking and packaging options to suit your project specifications.
Q5: What is the lead time for standard size orders?
For standard sizes, we offer fast lead times typically ranging between 3 to 5 business days, ensuring your projects remain on schedule.
