High-Pressure O-Rings

High-Pressure O-Rings

High-pressure O-rings are rubber sealing rings with a circular cross-section, designed for use in applications with extremely high pressure.

But which O-rings are suitable? Learn more in our guide below.

Types of High-Pressure O-Rings

High-pressure O-rings are available in various rubber compounds, including:

NBR (nitrile butadiene rubber) – Excellent resistance to greases, oils, fuels and chemicals.

FKM / FPM / Viton® (fluoroelastomer) – High tolerance to mineral oils, silicone greases, animal and vegetable fats.

EPDM (ethylene propylene diene monomer rubber) – Resistant to chemicals, steam, solvents and acids.

Hardness and Pressure Resistance

A key factor in choosing O-rings for high-pressure use is hardness. Common specifications include:

• 90 NBR ShA

• 80 NBR ShA

• 90 FKM ShA

• 80 FKM ShA

• 90 FPM ShA

• 80 FPM ShA

• 90 EPDM ShA

• 80 EPDM ShA

High-Pressure Rotary Seals

We also offer rotary seals for rotating applications, commonly used with shafts and moving components in pumps, electric motors, industrial gearboxes, wind turbines or household appliances.

Example: rotary seal for high-pressure systems.

Applications of High-Pressure O-Rings

High-pressure O-rings come in a wide range of hardness levels, materials and sizes, allowing for versatile use across many sectors:

• Technical industry

• Automotive industry

• Pharmaceutical industry

• Refinery operations

• Fuel and energy sectors

• Heavy-duty vehicles

• Excavators and cranes

• High-pressure equipment (e.g. pressure washer hose and drum fittings)
