Masking Straight Caps & Plugs

In stock

Straight Caps are an ideal solution for protecting and masking parts undergoing a variety of masking processes, including; painting, plating, powder coating, anodising, sand blasting, abrasive chemical processing, and processes that expose parts to high temperatures. They are highly versatile and can also be used as a plug to mask threaded or non-threaded holes.

These Masking Caps and Plugs can be used to protect studs, pins, tube ends and other applications that require protection. They are available in a choice of materials with a wide range of colour options to suit your project requirements. The range includes options moulded from a specially formulated silicone rubber that contains no colouring agent, which could bleed under high temperature conditions.

  • Materials: Ethylene Propylene Diene Monomer (EPDM) and Silicone Rubber
  • Colours: Black, Blue, Green, Grey, Natural, Orange, Pink, Purple and Yellow
