O-ring EPDM 139,2x5,7 Static Industrial Water and Steam Seal

High-Temperature & Chemical-Resistant Seal

The O-ring EPDM 139,2x5,7 is a static sealing solution engineered for industrial water and steam installations requiring stable compression, resistance to moisture and long term durability in non oil environments.

Within the static sealing O-rings EPDM category, the 139,2x5,7 mm model extends the medium to large diameter range, offering an increased 5,7 mm cross section for improved sealing stability in flange and cover connections.

The O-ring EPDM 139,2x5,7 is a water and steam resistant elastomer seal designed specifically for static industrial applications where consistent compression and environmental resistance are critical.

Construction and Material Characteristics

Manufactured from EPDM elastomer with standard 70 Shore A hardness, this O-ring provides:

• High elasticity for reliable installation

• Strong resistance to ozone and weathering

• Stable compression set in static assemblies

• Good compatibility with water and glycol based fluids

The dimensional combination of 139,2 mm internal diameter and 5,7 mm cross section allows uniform sealing pressure along larger circumferences, especially in static flange joints.

Long tail phrases: O-ring EPDM 139,2x5,7 mm, 139,2 mm ID 5,7 mm EPDM O-ring, static EPDM O-ring for heating systems.

This EPDM O-ring is not recommended for mineral oils or fuel applications, where NBR or FKM materials are typically required.

Industrial Applications

The O-ring EPDM 139,2x5,7 is commonly used in:

• Central heating installations

• Heat exchangers

• Industrial water systems

• Tank covers and inspection hatches

• HVAC and building service equipment

As a static seal, it is intended for assemblies without significant relative movement between components, ensuring reliable long term sealing performance.

Operational Advantages

For maintenance teams and procurement departments, this model offers:

• Reduced leakage risk in water systems

• Reliable sealing in medium to large diameter connections

• Good performance in humid and outdoor environments

• Cost effective solution for water based industrial circuits

The 5,7 mm cross section enhances the ability to compensate for minor surface irregularities in flange joints.
