In-Depth Product Overview: Square Rubber Ring

RUBBER-KU’s square rubber ring, also referred to as:

  • Square Cut O-Ring
  • Washer Ring
  • Lathe-Cut Ring
  • TetraSeal®

is a high-performance sealing element with a square or rectangular cross-section, designed to deliver enhanced sealing efficiency compared to traditional round O-rings.


Engineering Advantages Over Standard O-Rings

1. Increased Sealing Surface Area

Square rubber rings provide larger contact surfaces, resulting in:

  • Improved sealing integrity
  • Reduced leakage risk
  • Better load distribution

2. Superior High-Pressure Performance

Capable of handling pressures exceeding 1500 psi, making them ideal for:

  • Hydraulic systems
  • Industrial pumps
  • High-pressure valves

3. Anti-Rolling & Anti-Twisting Design

Unlike round O-rings, square rings:

  • Remain stable during installation
  • Prevent twisting or spiral failure
  • Ensure consistent sealing performance

4. Reduced Need for Backup Rings

The square geometry minimizes extrusion risk, often eliminating the need for additional support components.

5. Direct Interchangeability

Square rubber rings are designed to fit standard AS568 O-ring grooves, allowing:

  • Easy replacement
  • Reduced downtime
  • Cost-effective upgrades

Technical Specifications

  • Cross-section: Square / Rectangular
  • Hardness: Typically 40–90 Shore A
  • Temperature Range: -60°C to +250°C (depending on material)
  • Pressure Resistance: Up to 1500 psi or higher
  • Tolerance: Precision controlled per application requirements

Advanced Manufacturing Process

RUBBER-KU employs state-of-the-art manufacturing techniques to ensure superior product consistency:

1. Material Compounding

Custom rubber formulations are developed to meet specific:

  • Chemical resistance
  • Temperature requirements
  • Mechanical properties

2. Extrusion Process

Rubber compounds are extruded into precise tubing profiles, ensuring uniform material distribution.

3. Precision Lathe-Cutting

Using high-precision CNC machines, rings are cut into accurate square cross-sections, delivering:

  • Smooth sealing surfaces
  • Consistent dimensions
  • Tight tolerances

4. Finishing & Quality Inspection

Each product undergoes:

  • Surface finishing
