High Temperature Masking Caps

 (6 product groups)

Our high temperature masking caps offer reliable and effective protection for critical surfaces during a variety of high-temperature applications. At Essentra Components ZA, we understand the importance of ensuring that your components stay clean, protected, and free from surface contamination.

Our high temperature masking caps are the perfect solution for protecting threaded and non-threaded holes from damage during high-temperature coating and finishing processes.

High Temp Caps - the benefits

  • Protects critical surfaces: Our high temperature masking caps are designed to prevent contamination and damage to critical surfaces during high-temperature applications, such as powder coating, painting, and anodizing.
  • High-temperature resistance: Our caps can withstand extremely high temperatures, while also remaining flexible and durable.
  • Easy to use: Our high temperature masking caps are designed for easy installation and removal, without the need for any special tools or equipment. They are available in various shapes and sizes to fit different applications.

Common Applications

Our high temperature masking caps are suitable for a wide range of industries, including automotive, aerospace, and electronics, as well as general manufacturing processes.

  • Automotive: Commonly used in the automotive industry for protecting engine components during high temperature coatings.
  • Aerospace: Can be used in the aerospace industry to protect critical components during high temperature finishing processes.
  • Electronics: They are ideal for use in the electronics industry, where they can be used to protect connectors and other sensitive components during high temperature soldering and coating processes.

Easy Pull Masking Caps

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 one-time uses.

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

Expandable Masking Covers

Expandable Masking Covers are an ideal alternative to a more conventional cap when the part to cover has an awkward shape. The Masking Covers are expandable by stretching with an elasticated end or by stretching through the elasticity of the material. The elasticated cap makes it a looser hold and therefore is best for a general protection during transport and storage or light masking requirement.

The stretched material cap has a stronger hold on the part by gripping and therefore is best for application putting pressure on the part. Their softening point is at 90 degrees Celsius and they can be used up to 100 degrees Celsius.

  • Material: LDPE, Silicone
  • Colour: Blue, Red, White, Clear

Masking Straight Caps

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.

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


Series Code :SR1052, SR1095

Masking Washer Caps

A range of Masking Washer Caps that can be applied as a protective cap for threaded and non-threaded end tip.

Although the product is primarily designed as a cap, the integrated washer masks of grounding and also provides edge protection to ensures that the application hole is safe from contaminants and damage. This highly versatile masking solution can also be inverted and used to plug holes.

  • Material: Silicone (55 Shore A)
  • Maximum Temperature: 316 degrees C (600 degrees F)
  • Colours: Black, Green, Grey, Natural, Pink, Purple, Red and Yellow


Series Code :SR5756

Tapered Paper Caps

Tapered paper caps are a type of protective cap used to cover the ends of tubes, pipes or other cylindrical objects. They are made from a mixture of post-consumer and virgin materials, making them a recyclable option.

Ideal for painting and powder coating applications and can help prevent damage and contamination, ensuring that tubes and pipes are in good condition. It can withstand operating temperatures of up to 204 C.
