🧩 Product Description & Working Principle

RUBASIA’s Square Internal Rubber Cap is a high-performance protective insert designed to fit securely inside the hollow square tubing of furniture, equipment, or frameworks. Once inserted, the cap creates a tight internal seal that:

• Prevents direct metal-to-floor contact
• Absorbs vibration and impact shock
• Reduces noise from movement or dragging
• Seals the tube interior from dust, rust, and water ingress

This innovative product ensures both functional protection and aesthetic finishing for all square metal or plastic tubing applications.

 

🧠 Functional Benefits & Key Features

1. Superior Floor Protection
   Prevents deep scratches, abrasions, and dents on wooden, vinyl, marble, epoxy, and ceramic flooringcommonly found in offices, homes, and industrial facilities.
2. Noise & Vibration Control
   Acts as a natural sound dampener, muffling squeaks and vibrations produced during furniture movement or machine operation — ideal for offices, schools, hospitals, and labs.
3. Internal Fit Technology
   Designed to be inserted directly inside the tubing rather than over it, ensuring a neat, clean, and secure appearance with no external protrusion.
4. Non-Slip Grip Surface
   The rubber texture offers anti-slip resistance, increasing furniture stability on smooth floors.
5. Weather, UV & Ozone Resistant
   Formulated for indoor and outdoor use, resistant to Borneo’s tropical climate — including high humidity, rainfall, and UV exposure.
6. Anti-Corrosion Protection
   Seals the interior of hollow tubing, preventing the accumulation of moisture, rust, and insects.
7. Long-Term Cost Efficiency
   Extends the lifespan of both furniture and flooring by reducing wear and tear, minimizing maintenance or replacement costs.

 

🛠️ Installation Guide

Step 1: Measure the internal dimensions of your square tubing accurately (use a caliper).
Step 2: Choose the corresponding RUBASIA Square Internal Rubber Cap that matches your tubing size.
Step 3: Clean the inner surface of the tube (remove dust, oil, or rust).
Step 4: (Optional) Soften the rubber by soaking it in hot water (50°C–60°C) for a few minutes to improve flexibility.
Step 5: Push or tap the cap into the tubing until fully inserted. For tight fits, use a rubber mallet to tap gently.
Step 6: Check for secure fitting — the cap should be flush with the end and firm in place.
