Kaxite Sealing EPDM Flange Rubber Gaskets offer superior sealing solutions for industrial applications. Made from durable EPDM material, these gaskets resist extreme temperatures, chemicals, and weathering, ensuring leak-proof performance in pipelines and machinery. Perfect for engineers and maintenance teams across industries like HVAC, automotive, and water treatment, they provide reliable, long-lasting protection that reduces downtime and costs. Enjoy peace of mind with enhanced safety and efficiency—choose Kaxite Sealing for quality you can trust.
EPDM Flange Rubber Gaskets – Durable Sealing for Demanding Environments
Kaxite Sealing manufactures high-quality EPDM flange rubber gaskets engineered for reliable sealing performance across a wide range of industrial applications. EPDM (Ethylene-Propylene-Diene-Monomer) rubber offers exceptional resistance to ozone, UV radiation, weathering, and aging – making it the material of choice for outdoor and water-exposed environments. Our EPDM gaskets deliver leak-proof sealing for pipeline flanges, HVAC systems, water treatment facilities, and low-pressure boiler connections.
What sets Kaxite apart? Our EPDM flange gaskets are manufactured using precision compression moulding and automated cutting technologies, ensuring consistent dimensions and surface finish across every batch. We source only premium EPDM compounds from certified suppliers, and each production lot undergoes rigorous quality testing – including hardness, tensile strength, elongation, and compression set – to guarantee reliable sealing performance in your critical applications.
With our custom OEM/ODM capabilities, we supply EPDM gaskets in virtually any size, thickness, and flange configuration – from standard ANSI/ASME flanges to custom-designed shapes. Whether you need bulk wholesale quantities for maintenance inventory or just-in-time delivery for project deadlines, Kaxite Sealing is your trusted rubber gaskets manufacturer.

Frequently Asked Questions
- Q: What is EPDM rubber and why is it used for flange gaskets?
- A: EPDM (Ethylene-Propylene-Diene-Monomer) is a synthetic rubber known for exceptional resistance to weathering, ozone, UV radiation, and aging. It performs excellently in hot and cold water, steam, and dilute acids – making it the preferred choice for outdoor flange sealing, HVAC systems, water treatment, and low-pressure boiler applications. However, EPDM is not recommended for oil or fuel service.
- Q: What temperature range can EPDM gaskets handle?
- A: Standard EPDM gaskets operate continuously from –40 °C to +120 °C. For higher temperature applications, we recommend silicone rubber gaskets or FKM gaskets for up to +250 °C.
- Q: Are your EPDM gaskets FDA-compliant for food contact?
- A: Yes. We offer FDA 21 CFR 177.2600 compliant EPDM grades specifically for food and potable water applications. Please specify the FDA requirement when ordering and we will provide the appropriate certification documentation.
- Q: What sizes and thicknesses are available?
- A: We manufacture EPDM flange gaskets in virtually any size and thickness (1.0 – 25.0 mm). We can produce gaskets to ANSI/ASME, DIN, BS, JIS, or custom flange specifications. Contact us with your requirements for a quick quote.
- Q: What is the typical lead time for custom gaskets?
- A: Standard sizes: 7–15 working days. Custom dimensions: 15–25 working days, depending on order volume and complexity. Expedited production is available for urgent requirements – request a quote for specific delivery timelines.
- Q: Do you provide samples before bulk orders?
