O-ring 18x2 EPDM 70 Shore A - technical sealing ring

Design and construction

O-ring 18x2 EPDM 70 Shore A is manufactured from high-quality EPDM elastomer, designed for applications requiring resistance to water, steam and environmental factors.

Key construction features:

• inner diameter 18 mm
• cross section 2 mm
• precise round profile for uniform sealing
• flexible yet durable structure

EPDM material is especially suitable for environments where resistance to external conditions is critical.

Industrial applications

O-ring 18x2 EPDM 70 Shore A is widely used in systems where contact with water, air or outdoor conditions occurs.

Typical applications include:

• water installations and plumbing systems
• pneumatic systems operating with clean air
• HVAC systems and heating installations
• outdoor machinery and equipment
• food and water processing equipment

Within the technical sealing O-rings category, EPDM variants like this model are essential where NBR cannot be used due to limited resistance to weather or steam.

Technical parameters

• Type: O-ring EPDM
• Size: 18x2 mm
• Material: EPDM
• Hardness: 70 Shore A
• Temperature range: -40 to +120 C
• Color: black

Technical performance note:
O-ring 18x2 EPDM 70 Shore A provides stable sealing in water and steam environments, maintaining elasticity even under temperature fluctuations and exposure to ozone.

Operational advantages

This EPDM O-ring offers several key benefits:

• excellent resistance to water and steam
• high resistance to ozone, UV and weathering
• long service life in outdoor conditions
• stable elasticity over wide temperature ranges

Compared to standard NBR O-rings, this model is the preferred choice for applications exposed to environmental factors and non-oil-based media.

Main description

O-ring 18x2 EPDM 70 Shore A is a specialized sealing ring designed for systems exposed to water, steam and environmental conditions, ensuring long-lasting sealing performance and resistance to aging.

The 18x2 mm size is commonly used in installation systems, making this model a practical solution for both maintenance and production environments. EPDM material ensures that the O-ring maintains its sealing properties even in demanding outdoor or humid conditions.

In industrial sealing technology, EPDM O-rings play a critical role in applications where resistance to weathering, ozone and temperature changes is required. This makes the 18x2 EPDM 70 Shore A O-ring a reliable component in water systems, HVAC installations and external machinery.
