SYNTHETIC RUBBER Square Rings – High-Performance Sealing Solution

What is a Square Ring?

A SYNTHETIC RUBBER Square Ring is a premium sealing device designed in a torus shape (round top view) with a square cross-section (side view). Also known as Washer Rings or Lathe-Cut Rings, these seals provide superior sealing performance in high-pressure and static applications.

Why Choose Square Rings Over O-Rings?

Square Rings offer a larger sealing surface area compared to standard O-rings, ensuring a tighter, more reliable seal—without requiring design changes. They are interchangeable with O-rings and fit seamlessly into existing O-ring grooves, making them a cost-effective upgrade.

Key Benefits of Square Rings:

• Direct O-Ring Replacement – Fits standard O-ring grooves (same size)
• Superior Sealing Performance – Enhanced pressure resistance vs. O-rings
• Wide Material Selection – Available in NBR, Viton®, EPDM, Teflon®, and more
• Precision Engineered – Homogeneous construction with no weak joints
• Consistent Quality – Tight tolerances on ID, OD, and cross-section
• Versatile Applications – Ideal for static, radial, and high-pressure seals
• Cost-Effective – Modern, high-performance alternative to traditional seals

Applications of Square Rings

Square Rings are widely used in industries requiring high-pressure sealing solutions, including:

• Hydraulics & Pneumatics
• Automotive & Aerospace
• Oil & Gas Equipment
• Industrial Machinery
• Medical & Food-Grade Systems

Available Materials & Custom Options

Square Rings are manufactured in various synthetic rubber and plastic compounds, ensuring compatibility with different environments:

• NBR (Nitrile) – Oil & fuel resistance
• Viton® (FKM) – High-temperature & chemical resistance
• EPDM – Weather & ozone resistance
• Teflon® (PTFE) – Extreme chemical & thermal stability

Upgrade to Square Rings for Better Sealing Performance

For static sealing applications, Square Rings outperform traditional O-rings while maintaining cost-efficiency. Their precise engineering, durability, and material versatility make them the ideal choice for industrial, automotive, and hydraulic systems.

• Interchangeable with O-rings
• Fits standard grooves – No redesign needed
• Higher sealing efficiency at competitive pricing
