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)

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.
