Frequently Asked Questions
What material is best for my application?
The choice depends on temperature, chemical exposure, and pressure requirements. NBR is ideal for general hydraulic oil applications; FKM/Viton for high-temperature and chemical resistance; Silicone for food-grade and medical; EPDM for water/steam. Please share your working conditions and we will recommend the optimal material.
Can you produce custom sizes and materials?
Absolutely. We specialize in custom molded O-rings. You can provide drawings, samples, or dimensions, and our engineering team will design and manufacture to your exact specifications. Custom compounds and colors are also available.
What is your minimum order quantity (MOQ)?
Our standard MOQ is 100 pieces per size, but we are flexible for trial orders and new clients. Contact us with your requirements and we will work out the best solution for you.
Do you provide free samples?
Yes, we offer free samples of standard sizes. For custom sizes, a small mold fee may apply. Samples are usually shipped within 3-5 working days via express courier.
