What is a Square Rubber Ring?
A square rubber ring, also commonly known as a square cut O-ring, washer ring, lathe-cut ring, or TetraSeal®, is a sealing component designed with a square or rectangular cross-section profile. Unlike conventional round O-rings, square rubber rings provide a larger sealing contact surface, making them highly effective in static sealing applications and high-pressure environments.
These advanced sealing rings are widely used in:
- Hydraulic systems
- Pneumatic equipment
- Flanges
- Pumps
- Valves
- Pistons
- Compressors
- Pipe fittings
- Industrial machinery
- Automotive sealing systems
Square rubber rings are engineered to minimize leakage of liquids, gases, oils, chemicals, and air under demanding operating conditions.
Why Choose RUBBER-KU Square Rubber Rings?
Superior High-Pressure Sealing Performance
RUBBER-KU moulded square rubber rings provide enhanced sealing efficiency compared to traditional round O-rings. Their flat sealing surface creates greater contact area, allowing superior sealing capability in high-pressure applications often exceeding 1500 PSI.
Excellent Stability During Installation
Unlike round O-rings that may twist or roll during assembly, square rubber rings maintain better groove stability, ensuring easier installation and more reliable sealing performance.
Reduced Extrusion Risk
Due to their square cross-sectional design, these sealing rings resist extrusion effectively and often eliminate the need for backup rings in many industrial sealing applications.
Direct Replacement for Standard O-Rings
Our square rubber rings are designed to fit standard AS568 O-ring grooves, enabling easy replacement and compatibility with existing sealing systems.
