  • 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)
Threaded Protection Plugs

Threaded Protection Plugs

  • 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)
Tear Tab Caps

Tear Tab Caps

  • 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.
