High Temperature Masking Caps

 (7 product groups)

What are masking caps used for?

High temperature masking caps, also known as masking plugs or caps, are used in various industrial applications to protect specific areas or components from exposure to high temperatures during processes like painting, powder coating, anodizing, or other surface treatments.

High temperature masking cap applications 

High temp masking caps play a crucial role in ensuring that specific areas of a component or product remain protected during various industrial processes such as:

Powder Coating: During this process, parts are coated with a fine powder and heated to create a durable finish. High temp masking caps protect areas that shouldn't be coated.

Anodizing: This electrochemical process forms a protective oxide layer on metals like aluminum. Masking caps keep specific areas untreated.

Blasting and Etching: During processes like sandblasting or chemical etching, masking caps shield areas from abrasives or chemicals.

Painting: In automotive or industrial painting, masking caps cover sensitive areas like holes and threads to prevent unwanted paint application.

Our range features masking caps made from various materials including silicone, plastic, EPDM and more.

Easy-Pull Masking Caps

In stock In production

Easy Pull Masking Caps provide optimum protection for end tip profiles, such as rods, pipes and tubes during manufacturing processes. Typical applications include; anodizing, blasting, powder coating, e-coating, plating and general paint lines.

This range has several style options, include a range with a flanged design and an internal seal that provides a secure fit or options that feature an ergonomic finger pull-tab for easier removal.

These caps are easy to fit; to ensure the best possible fit, the inside diameter dimension should be approximately 10 percent smaller than the outside diameter of the part being masked.

Our range is available in different material options with various beneficial properties. Silicone is a premium masking material with high temperature and chemical resistance. EPDM is a more economical material option with lower heat resistance. Both Silicone and EPDM options can be used multiple times. Whereas, Soft PVC is a more economical solution also with chemical resistance, a reduced heat resistance and is for single-use applications.

  • Materials: Silicone Rubber 600F (316C) EPDM 425F (218C) and Soft Polyvinyl Chloride (PVC) 425F (218C)
  • Colors: Natural, Black and Yellow
  • Hardness: Durometer (Shore A) 55 + 5 and 85 +/–2

Masking Straight Caps

In stock In production

These Masking Straight Caps are typically used to mask studs and tube ends. They have excellent sealing capabilities due to the flexible material that they are manufactured from. Ideal applications include; powder coating, e-coating, plating, anodizing and blasting.

Although they are primarily designed fpr use as a cap, if inverted, they can also be used to plug holes.

Available in a choice of two materials; Silicone and EPDM. Silicone is a premium masking material due to its high temperature and chemical resistant properties. EPDM is a more economical material option with a lower heat resistance but superior chemical resistance. Both material options can be used multiple times.

  • Materials: Silicone 60F (316C) and EPDM 425F (218C)
  • Colors: Blue, Black, White, Green, Grey, Pink and Yellow
  • Hardness: Durometer (Shore A) 55+5
