Ensure smooth assembly and transit by protecting critical internal and external profiles from damage while maintaining quality.
Protect your design with:
- Suitable to plug ISO A and ISO B series
- TPE material
- For threaded or plain parts
- Pull tab for quick removal
- Service temperature range: -40°C – 95°C (-40°F – 203°F)
- Fully threaded to 13.6 mm/ 0.535 in
- LDPE material
- Also used in hydraulic and pneumatic industries
- Knurled head for easy grip
- Service temperature range: -40°C – 65°C (-40°F – 149°F)
- Suitable as NPT thread plug, and UNF
- LDPE material
- When tab is pulled, cap splits open for quick removal
METAL FABRICATION
Data cabinet • Sheet metal • Furniture
Increase customer satisfaction with a professional finish by masking holes and contact points with easy-to-fit caps and plugs.
Guard your product’s holes with:
High-Temperature Silicone Tapered Plugs
