Выбор правильного EPDM O-ring is critical to ensure weather resistance, chemical stability, and durability in your sealing application.

EPDM O-rings offer excellent resistance to steam, UV, and weather conditions, ideal for outdoor and water systems.

Let’s explore how to use EPDM O-rings effectively across industries.

What are EPDM O-rings used for?

EPDM O-rings are made from ethylene propylene diene monomer, which gives them their robust weather and chemical resistance.

Они обычно используются в:

• Steam and hot water systems
• Automotive braking and cooling systems
• Outdoor sealing (HVAC, solar panels)

Are EPDM O-rings chemically resistant?

Yes, EPDM’s saturated polymer structure resists oxidation and UV. It's ideal for polar solvents, steam, and weathering.

Can EPDM O-rings be used outdoors?

Absolutely. EPDM performs extremely well outdoors:

• Resistant to UV and ozone
• Doesn’t crack in sunlight
• Handles temperature swings (-50°C to 150°C)

That’s why they’re often used in rooftop solar panels and HVAC systems.

When should you avoid EPDM O-rings?

Do not use EPDM where oils, fuels, or hydrocarbons are present.

How to choose the right EPDM O-ring?

Use this 3-step checklist:

1. Диапазон температур: EPDM works between -50°C and 150°C
2. Химическое воздействие: Avoid oils, use in polar solvents, water
3. Sizing: Measure ID, OD, and CS; verify Shore A hardness
