🧪 TECHNICAL PRODUCT DESCRIPTION

Our Rubber Tube Stopper is a high-precision tapered plug designed for sealing applications requiring:

• Chemical resistance
• Dimensional accuracy
• Elasticity & compression strength
• Non-reactivity with chemicals
• Airtight & liquid-tight integrity

Each stopper is moulded with controlled density, ensuring consistent:

• Hardness (Shore A rating)
• Tensile strength
• Tear resistance
• Compression set recovery
• Thermal stability

These plugs form a secure interference fit, allowing for pressure-resistant sealing in both static and dynamicenvironments.

 

🛠️ PRODUCT FEATURES

1. Injection or compression moulded for perfect dimensional accuracy

Ensures uniform taper geometry from top to base, allowing precise engagement in tubes, pipes, and containers.

2. Laboratory-Grade Smooth Surface Finish

Prevents contaminants from adhering and enables easy cleaning and sterilization.

3. Ultra-Fine Taper Engineering

• Creates progressive sealing pressure
• Enhances grip the deeper it sits
• Prevents micro-leak pathways

4. Heat & Chemical Resistance

Suitable for:

• Acids
• Alkalis
• Oils
• Solvents
• Aqueous solutions
• Organic liquids

5. Dual-Color Purpose Engineering

Red:

• Lab-safe visibility
• Sample identification
• Color coding systems

Black:

• Industrial toughness
• Outdoor durability
• Mechanical workshop use

6. Temperature Tolerance

Typically withstands:

• -20°C to +110°C (rubber grade dependent)
• Stable under autoclave sterilization (lab-grade models)

7. High Elastic Memory

The rubber rebounds perfectly after compression, ensuring long-term reuse.

8. Anti-Vibration & Anti-Rebound Characteristics

Prevents the stopper from ejecting under internal pressure or vibration from equipment.
