⭐ PRODUCT FEATURES – RUBBER TUBE STOPPER | RUBBER TAPERED PLUG

Below is the most comprehensive, technical, and feature-focused description possible for your product.

 

1. High-Precision Tapered Geometry

• Engineered with an exact conical angle to ensure a progressive tightening effect as the stopper is inserted deeper.
• Guarantees zero-gap sealing, eliminating even microscopic leak paths.
• Suitable for both positive and negative pressure environments.
• Ensures perfect grip for test tubes, flasks, bottles, metal pipes, PVC pipes, HDPE tubes, stainless steel lines, and chemical containers.

 

2. Universal Multi-Diameter Fit

Each stopper covers multiple diameter ranges:

• The upper and lower diameter difference ensures that one stopper can fit various internal diameters.
• Reduces inventory count for laboratories and factories.
• Offers flexible matching between tube sizes, pipe bores, and opening tolerances.
• Ideal for applications where diameter variations occur due to thermal expansion or manufacturing tolerances.

 

3. Premium Industrial-Grade Rubber Compound

• Manufactured using high-density, high-elastomer pure rubber.
• Formulated to withstand long-term compression without permanent deformation.
• Retains elasticity even after repeated use under mechanical stress.
• Ensures excellent sealing performance in environments with moisture, chemicals, or fluctuating temperatures.
• No cracking, hardening, or shrinkage over time.

 

4. Superior Chemical Resistance

The rubber compound offers resistance to:

• Acids (mild to moderate)
• Alkalis
• Oils and lubricants
• Water and steam
• Solvents
• Cleaning agents
• Alcohols
• Organic and inorganic chemicals

This makes it suitable for:

• Laboratory chemical experiments
• Industrial chemical processing
• Water treatment industries
• Pharmaceutical production

 

5. Airtight & Liquid-Tight Sealing Technology

• Provides complete barrier protection against air, moisture, dust, and chemical vapor intrusion.
• Ensures laboratory samples remain uncontaminated.
• Prevents leakage during pressure tests, hydrostatic tests, and pipe flushing operations.
• Maintains vacuum seal in test tubes and experimental setups.

 

6. Dual-Color Options for Functional Identification

Red Rubber Stopper

• Ideal for laboratory environments requiring sample differentiation.
• Highly visible, assists in prioritizing experiments.
• Suitable for chemical storage identification and hazard markings.

Black Rubber Stopper

• Built for industrial-grade durability.
• Withstands rough handling, industrial chemicals, outdoor exposure.
• Preferred for heavy-duty use in workshops, construction sites, and engineering operations.

 

7. Wide Temperature Tolerance Range

• Stable performance between -20°C and +110°C.
• Some batches can withstand brief autoclave sterilization depending on formulation.
• Resists thermal expansion and contraction without losing sealing integrity.

 

8. Non-Slip External Grip Surface

• The outer surface texture provides frictional engagement, preventing accidental loosening.
• Holds firmly even when exposed to:
  • Oil
  • Water
  • Vibration
  • Movement

 

9. High Compression Strength and Elastic Memory

• Engineered for repeated plug–unplug cycles.
• Retains original shape after compression loading.
• Does not deform permanently even after long-term use.
• Perfect for laboratory applications requiring frequent stopper replacement.

 

10. Anti-Vibration Performance

• Rubber material absorbs vibration and shock.
• Prevents the stopper from loosening during:
  • Equipment movement
  • Mechanical vibration
  • Transportation
  • Pressure fluctuations
• Essential for industrial pipeline testing and portable lab kits.

 

11. Tough, Tear-Resistant Construction

• Designed for environments where the stopper may experience:
  • Pulling
  • Twisting
  • Pressure loading
  • Abrasion
• High tear strength ensures reliability even under harsh use.

 

12. Smooth, Non-Porous Finish

• Prevents contamination buildup.
• Enables easy cleaning and sterilization.
• Suitable for hygiene-sensitive environments such as:
  • Food processing
  • Medical labs
  • Pharmaceutical manufacturing

 

13. Reusable & Cost-Efficient

• Long lifespan reduces replacement costs.
• Chemical resistance ensures it outlasts cork stoppers, foam plugs, and inferior rubber types.
• Maintains performance across repeated laboratory cycles.

 

14. Precise Size Availability (T03–T51)

• Each model size is engineered to exact tolerances.
• Ensures perfect matching between stopper and tube diameter.
• Addresses both micro-lab scale and large industrial diameter requirements.

 

15. Leak-Proof Performance Under Pressure

• Forms a strong seal that prevents:
  • Leak-back
  • Vapor escape
  • Drip leakage
  • Chemical seepage
• Ideal for:
  • Hydrostatic testing
  • Pressure retention experiments
  • Sample transportation
  • Underground pipeline testing

 

16. Environmentally Stable & Aging-Resistant

• UV-resistant and oxidation-resistant depending on rubber grade.
• Suitable for outdoor and long-duration industrial exposure.
• Maintains flexibility under high humidity and tropical climates—ideal for Sabah, Sarawak, Brunei weather.

 

17. Compatible with Multiple Industries

The features make it suitable for:

• Laboratories
• Chemical plants
• Research universities
• Automotive workshops
• Construction companies
• HVAC & M&E contractors
