🔲 Product Overview: Square Internal Rubber Cap

The Square Internal Rubber Cap by RUBASIA RUBBERTECH INDUSTRIES is a durable, high-grade rubber insert designed to fit inside square-shaped hollow tubing—commonly found on chair legs, table legs, machine frames, racks, or trolleys.

It acts as a protective and noise-reducing buffer between the furniture and the floor surface. The product enhances both safety and aesthetic finish, providing long-term protection against impact, friction, vibration, and moisture.

3. Anti-Slip and Stability
   The rubber base provides strong traction, reducing furniture slippage on smooth floors.
4. Sealing and Hygiene
   Prevents dust, moisture, and insects from entering hollow tubing — ideal for cleanroom or medical environments.
5. Impact and Vibration Absorption
   Cushions and absorbs shock from equipment vibration or heavy usage, extending the life of furniture and flooring.
6. Weather and UV Resistant
   Suitable for indoor and outdoor use — perfect for outdoor cafés, garden furniture, and public seating areas.

 

🛠️ Installation Method

Installing RUBASIA’s Square Internal Rubber Cap is simple and does not require tools:

1. Measure the Internal Tube – Use a caliper to measure the inside dimensions of your square tubing.
2. Select the Right Size – Choose a rubber cap that fits snugly inside (a slight compression ensures a tight grip).
3. Clean the Tube Interior – Remove debris, oil, and rust for proper seating.
4. Soften the Rubber (Optional) – Soak the cap in warm water (50–60°C) for 3–5 minutes to enhance flexibility.
5. Insert by Hand or Tap Lightly – Push the cap into the tubing opening. For larger sizes, use a rubber mallet to gently tap it in place.
6. Check for Firm Fit – Ensure the rubber sits flush and cannot be easily pulled out.
