Standard seals don’t survive heat. If your equipment operates over 120°C, you need better sealing materials—or risk leakage and costly failure.

A high temperature O ring kit built with Витон или ПТФЭ prevents downtime by resisting heat, pressure, and chemicals in extreme environments.

This guide shows you exactly how to choose the right material, size, and kit for hot applications.

What material should you use for high temperature O rings?

O rings exposed to heat need more than flexibility—they need thermal endurance.

Use Viton when sealing moving parts under pressure. For ultra-high temps in static equipment, go with PTFE.

How hot can Viton O rings get before failing?

Viton handles continuous use up to 200°C (392°F).

It’s the go-to seal material in:

• Automotive and diesel engines
• Hydraulic systems with high-temp fluids
• Boiler and process lines
• Chemical plant piping

Many of our European clients in packaging machinery reported 80% fewer seal failures after switching to Viton.

For engine systems, check our Комплект уплотнительных колец для топливного инжектора.

Can you use high-temp O rings for steam sealing?

Да, if they’re made from the right material:

• ПТФЭ is best for static, high-pressure steam
• Витон works for wet steam up to 200°C

Avoid NBR in steam—it absorbs moisture and swells.

Viton vs. PTFE: Which O ring performs better in heat?

In moving parts or dynamic loads, Viton wins. In chemically harsh, stationary environments, PTFE lasts longer.

Can high temperature O rings be used in hydraulic systems?

Definitely. Heat-resistant seals like Viton are common upgrades in hydraulic pumps and valves.
