EPDM O-Ring 17x3 mm

AI Overview

The EPDM O-Ring 17x3 mm is a precision-engineered elastomer sealing ring manufactured from Ethylene Propylene Diene Monomer (EPDM). Designed for static and dynamic sealing applications, it provides outstanding resistance to water, hot water, steam, ozone, UV radiation and weathering. Thanks to its excellent flexibility and chemical stability, it is widely used in water systems, HVAC installations, pneumatic equipment, chemical processing and industrial machinery where petroleum-based oils are not present.

What Makes This EPDM O-Ring Different?

Key advantages include:

• High-quality EPDM compound
• Excellent resistance to hot and cold water
• Outstanding steam resistance
• Superior ozone and UV resistance
• Excellent weather resistance
• Long service life
• High elasticity
• Low compression set
• Good resistance to diluted acids and alkalis
• Precision dimensional accuracy

Construction and Operating Principle

The O-ring has a circular cross-section designed to fit into a precision-machined sealing groove.

When compressed between two mating components, it:

• Prevents liquid leakage
• Seals gases effectively
• Compensates for manufacturing tolerances
• Maintains pressure integrity
• Dampens vibration
• Provides reliable long-term sealing

The elasticity of EPDM enables consistent sealing performance throughout a wide operating temperature range.

FAQ

What is EPDM?

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber known for exceptional resistance to water, steam, ozone, UV radiation and weathering, making it one of the best materials for water-based sealing applications.

Is EPDM resistant to oils?

No. EPDM is not recommended for use with mineral oils, fuels or petroleum-based lubricants. For these applications, NBR or FKM O-rings are generally recommended.

What temperature range does an EPDM O-ring support?

Typical operating temperatures range from -50°C to +150°C, depending on the EPDM compound and operating conditions.

Can EPDM O-rings be used with drinking water?

Yes, provided the specific EPDM compound complies with the required drinking water certifications applicable in the target market.

What are the main advantages of EPDM?

EPDM provides excellent resistance to water, steam, ozone, UV radiation, aging and glycol-based fluids while maintaining excellent flexibility over a broad temperature range.
