High-Temperature O-Rings

High-temperature O-rings are specially designed seals that operate reliably in extreme temperature conditions.

You might be wondering: What temperature range do I actually need?

At POWER Rubber, our experts have the answers. Here are the available options:

NBR O-Rings up to +90°C

Made from nitrile rubber, these are cost-effective and resistant to hydraulic oils. Ideal for standard industrial conditions.

HNBR O-Rings up to +150°C

Highly durable, resistant to ozone, oils, and sulfur-containing acids. Excellent abrasion and damage resistance. Suitable for demanding mechanical applications.

EPDM O-Rings up to +150°C

Commonly used in braking systems (DOT 3, DOT 4, DOT 5), resistant to hot water, steam, mild acids, and UV. Ideal for HVAC systems and machinery.

FEP O-Rings up to +205°C

Featuring a Teflon coating, these O-rings are more chemically resistant and suitable for a wide temperature range. Used in pharmaceuticals, petrochemicals, and areas requiring vibration damping.

Viton® FKM/FPM O-Rings up to +210°C

Excellent for use with mineral and synthetic oils, silicone greases, fuels, and diesel. Resistant to ozone, aging, and extreme weather. Ideal for automotive, aerospace, and mining applications.

Silicone O-Rings VMQ and FVMQ up to +240°C

Certified for food contact (FDA). Resistant to ozone, phenyls, hot air, and animal or vegetable oils. FVMQ offers enhanced fuel and abrasion resistance. Ideal for static applications.

PFA O-Rings up to +260°C

Suitable for contact with high temperatures. Their coating provides thermal resistance and elasticity.

High-Temperature O-Rings up to +300°C

Special VMQ blends withstand short-term exposure to +300°C.

Kalrez® FFKM O-Rings up to +327°C

Top-tier perfluoroelastomer seals for the harshest environments – crude oil, aerospace pressure changes, semiconductor manufacturing, and more. Used in chemical and pharmaceutical sectors.

Why choose the right high-temperature O-ring?

Choosing the right sealing solution minimizes downtime, boosts productivity, and reduces overall operational costs.
