Leading developer of high-performance elastomer materials for extreme environments.

Q1: What materials are rubber sealing O-rings made of?

A: Our Rubber sealing rings are made from various materials, including:

- NBR (Nitrile Rubber): Oil and fuel resistant.

- EPDM (Ethylene Propylene Diene Monomer): Weather and temperature resistant.

- Silicone: High-temperature and food-grade applications.

- FKM: Chemical and heat resistant.

- Neoprene: Abrasion and weather resistant.

- PTFE (Polytetrafluoroethylene): Chemical and corrosion resistant.

Q2: What sizes are available for rubber sealing O-rings?

A: Rubber sealing rings come in standard sizes (e.g., AS568, ISO 3601, DIN, JIS) and custom sizes. We provide metric and imperial measurements to meet your specific requirements.

Q3: Can I request custom-sized rubber sealing O-rings?

A: Yes, we offer custom sizing based on your specifications. Please provide the inner diameter (ID), outer diameter (OD), and cross-sectional thickness (CS) for accurate production.

Q4: What is the minimum order quantity (MOQ)?

A: Our MOQ is flexible, depending on the product and customization. We cater to both small and bulk orders.

Q5: What certifications do you offer?

A: We are certified with ISO 9001, ISO 14001, and IATF 16949, and comply with FDA, RoHS, and REACH standards. In addition, we hold over 30 patents.
