How to Install Round External Rubber Cap — Step-by-Step Guide by RUBASIA RUBBERTECH INDUSTRIES
Installing the Round External Rubber Cap is a simple, tool-free process that can be completed in minutes. Designed for both DIY users and industrial installers, these caps ensure maximum protection and perfect fit when properly installed.
Follow these detailed steps to achieve the best results:
Step 1: Identify the Object to Be Covered
Decide where the rubber cap will be used.
Common applications include:
- Furniture legs (chairs, tables, cabinets, racks)
- Metal pipes and steel tubing
- Bolts, rods, or round frame ends
- Hydraulic or pneumatic tube openings
Step 2: Measure the Outer Diameter
Use a digital caliper or measuring tape to measure the outer diameter of the round object (leg, pipe, or tube).
� Example: If your chair leg measures 25mm in diameter, select a 25mm Round External Rubber Cap.
RUBASIA provides a complete range of sizes (9mm, 12mm, 16mm, 19mm, 22mm, 25mm, 28mm, 32mm, 38mm, 51mm) — ensuring perfect fitment for any application in Sabah, Sarawak, or Brunei.
Step 3: Clean the Surface
Before installing, wipe the leg or pipe end clean using a dry cloth to remove dust, oil, or rust.
A clean surface ensures a tighter grip and longer lifespan of the cap.
Step 4: Prepare the Rubber Cap
For a smoother fitting:
- You may soak the rubber cap in warm water (about 40–50°C) for 1–2 minutes to soften it slightly.
- This helps when fitting over larger or tight metal tube ends.
� Avoid using excessive heat to prevent deformation.
Step 5: Fit the Rubber Cap
Hold the cap firmly and press it straight onto the round leg or tube.
Push until the rubber lip fully covers the end.
If resistance is high:
- Apply a small amount of soapy water or silicone spray on the leg for easier sliding.
- Do not use oil or petroleum-based lubricants, as they can degrade the rubber.
Step 6: Check the Fit
Ensure the cap:
- Sits evenly around the tube circumference.
- Does not wobble or slide off easily.
- Has full contact with the bottom surface.
A properly installed cap will stay firmly in place and offer excellent protection, anti-slip performance, and noise reduction.
Step 7: Test for Grip & Stability
Gently move the furniture or shake the tube to confirm that the rubber cap holds securely.
If it feels loose:
- Recheck the diameter measurement.
- Consider one size smaller for a snugger fit.
Step 8: Maintenance & Replacement Tips
To maintain performance, check the caps every few months:
- Wipe clean with mild soap and water.
- Replace any cap that shows cracks, flattening, or wear.
- Avoid prolonged contact with oils or strong solvents.
