O-Ring EPDM 228.19x3.53

Main Description

The O-Ring EPDM 228.19x3.53 is a high-quality industrial rubber seal ring designed for static sealing applications where reliability, chemical resistance and long service life are critical. The nominal inner diameter of 228.19 mm and a cross-section thickness of 3.53 mm make this O-Ring suitable for large flange connections, covers, housings and assemblies requiring robust sealing under pressure or environmental exposure.

Manufactured from EPDM (ethylene-propylene-diene monomer) elastomer, this O-Ring delivers excellent resistance to water, steam, polar solvents, dilute acids, alkalis, ozone, UV radiation, weathering and aging. EPDM seals remain flexible at low temperatures and maintain elasticity and sealing integrity over time, even under cyclic temperature and humidity changes — a major advantage for hydraulic, pneumatic, sanitary and water treatment systems, as well as HVAC and outdoor installations.

EPDM O-rings are widely recognized for their low compression set, good elasticity and resistance to steam and weather effects. This makes the O-Ring EPDM 228.19×3.53 an ideal solution for demanding static sealing tasks — providing watertight, airtight or fluid-tight sealing in valves, flanges, pumps, tanks and housings.

Key Advantages

• High chemical and environmental resistance - EPDM handles water, steam, polar solvents, mild acids/alkalis, ozone, UV and weather exposure with confidence.

• Reliable static sealing - round-section ring seals interfaces tightly under compression, ensuring leak-free operation in flanged joints, covers, housings and large-diameter connections.

• Durability and long service life - EPDM’s stable mechanical properties and resistance to aging and environmental stress deliver consistent sealing performance even after prolonged use.

• Wide temperature and media compatibility - suitable for water, steam, polar chemicals, HVAC fluids; stable performance from cold conditions up to industrial working temperatures (depending on curing).

• Ease of installation and maintenance - flexible rubber seal simplifies assembly, fits standard grooves or flange joints, and reduces maintenance needs compared to rigid sealing solutions.

Given these properties, O-Ring EPDM 228.19×3.53 is an optimal rubber gasket for industrial sealing needs — combining reliability, flexibility, and resistance in hydraulic, pneumatic, sanitary, HVAC, water treatment or general-purpose sealing systems.

FAQ

Q: What is EPDM and why is it used for O-rings?
A: EPDM stands for ethylene-propylene-diene monomer — a synthetic rubber offering high resistance to water, steam, UV, ozone and a variety of chemicals. Its flexibility and durability make it ideal for industrial sealing.

Q: For which applications is O-Ring EPDM 228.19×3.53 suited?
A: It is suitable for static sealing in flanges, housings, tanks, pumps, valves, hydraulic or pneumatic systems, water and steam installations, HVAC, sanitation, and general industrial sealing.

Q: What media and conditions can this O-ring withstand?
A: Water, steam, polar solvents, mild acids/alkalis, weather, UV, ozone, outdoor conditions, and broad temperature ranges (depending on EPDM compound and curing type).

Q: Is this O-ring suitable for oil-based hydraulic applications?
A: EPDM has limited compatibility with mineral oils or petroleum-based greases — for oil-heavy environments other elastomers might be more appropriate.

Q: How does O-ring sealing work?
A: The O-ring compresses between two mating surfaces (e.g. a flange and cover), closing the gap and forming a reliable seal. Under pressure, the sealing force increases, preventing leaks of fluids or gases.
