Ethylene Propylene (EPDM) O-Rings (0.275 Section)

Ethylene Propylene (EPDM) O-Rings (0.275 Section): Large-Profile Seals for Steam, Water, and Outdoor Environments

Ethylene Propylene (EPDM) O-Rings (0.275 section) from TFM are engineered for robust sealing in demanding static applications exposed to moisture, steam, ozone, and weathering. Manufactured from durable 5600-70 grade EPDM rubber, these large-section O-rings are particularly suited for HVAC, plumbing, steam processing, and outdoor utility systems where petroleum resistance is not required.

With a cross-sectional diameter of 0.275 inches, these O-rings offer strong compression and long-term sealing integrity, even in thermally dynamic environments. Their formulation provides excellent flexibility at sub-zero temperatures and reliable sealing performance up to +150°C.

Key Features:

Material Grade: 5600-70 EPDM Rubber
Durometer: 70 Shore A
Color: Black
Cross-Section: 0.275 inches
Temperature Range: –51°C to +150°C

Performance Benefits:

Outstanding resistance to steam, water, ozone, and UV exposure
Maintains elasticity in low-temperature conditions
Low compression set for static applications
Electrically non-conductive and suitable for use in outdoor electrical enclosures
Not suitable for use with petroleum-based oils, fuels, or solvents

Typical Applications:

Static flange and housing seals in steam and water systems
Outdoor seals in rooftop HVAC, solar devices, and weatherproof cabinets
Seals in chlorinated water handling, cooling towers, and humidifiers
Electrical equipment gaskets where moisture ingress and UV resistance are concerns

TFM’s EPDM O-Rings (0.275 section) deliver consistent sealing performance where large-profile elastomers must endure thermal cycling, weathering, and steam exposure, making them an optimal choice for industrial and environmental sealing solutions.
