Frequently Asked Questions

Q: What is the difference between FKM and standard rubber for water meter seals?

FKM (Fluoroelastomer) offers significantly higher resistance to chemicals, heat, and aging compared to standard rubber, ensuring a longer life and zero leaks in varied water conditions.

Q: Can you manufacture seals based on a custom CAD drawing?

Yes, we fully accept 3D and CAD drawings. Our engineering team can customize the size, profile, and hardness (30-90 Shore A) to meet your exact specifications.

Q: What certifications do your rubber parts comply with?

Our products are manufactured under ISO9001:2008 standards and have passed RoHS, CTI, and TS16949 certifications to ensure global compliance.

Q: Do you provide free samples for testing?

Yes, we offer free samples to ensure the quality and fit meet your requirements. The customer is only responsible for the freight costs.

Q: What is the typical delivery time for a custom rubber order?

Typically, our delivery lead time ranges from 7 to 10 days, depending on the complexity of the mold and the order volume.

Q: How do you ensure the quality of each rubber seal?

We implement a three-stage QC process: full mold size inspection, semi-finished product monitoring, and final batch appearance/dimension checks.
