Silicone Plug Manufacturer & Supplier in India
Easkay India is a silicone plug manufacturer in India, manufacturing and supplying these for closing, protecting, masking, and sealing holes, ports, openings, and fittings in industrial components. These are particularly useful where the application involves high temperatures, flexible fitting, or repeated installation and removal.
Silicone Plug Specifications & Dimensions
The diameter, insertion length, and head dimensions are the main specifications. The hole size and required fit should be considered to ensure the plug is easy to install while remaining securely in position.
Silicone Plug Material & Performance
Silicone rubber is suitable for plugs where high temperature silicone plugs resistance, flexibility, weather resistance, and good ageing performance are required. Its flexible nature allows the part to adapt to different openings while maintaining contact with the surrounding surface. The suitable grade and hardness depend on the temperature, compression, hole geometry, repeated use, and working environment.
Silicone Plug Manufacturing
These are produced through rubber moulding, using tooling designed according to the required diameter, length, head profile, and sealing features. Moulding allows consistent production of different shapes and sizes. Design features such as tapered sections, grip areas, heads, grooves and steps can be incorporated where required for easier installation and better holding.
Silicone Plug Fit & Application Requirements
For selecting the correct plug, the hole diameter, insertion depth, diameter, head size and required fit should be specified. The installation and removal method should also be considered, particularly where the part is used repeatedly.For masking applications, details such as process temperature, coating method, chemical exposure, hole geometry and expected reuse help determine the suitable design.
Custom Silicone Plug Development
Easkay India can develop custom silicone plugs from an engineering drawing, CAD model, physical sample or specified dimensions. Once the design and material are approved, the finalised specification can be retained for repeat production and regular supply.
Industrial Applications of Silicone Plugs
These are commonly used for:
- High-temperature masking processes
- Painting and powder coating
- Plating and surface treatment
- Protecting holes and ports
- Sealing openings during processing
- Electrical and electronic components
- Industrial machinery
- Automotive components
They are especially useful in masking applications, where selected holes or openings need to remain free from paint, powder, chemicals, or other finishing materials.
