Alliance Express stocks and distributes many sizes and styles of masking caps. These caps can be used for a variety of applications, including: powder coating, e-coating, plating, anodizing and blasting.
One of the largest and most popular series of masking caps is our offering of straight masking caps. These caps provide excellent sealing due to the flexible material and are commonly used for masking studs and tube ends. Although these are designed as a cap, they can be used to plug holes if inverted. Straight masking caps are available in silicone and EPDM. Silicone is a premium masking material due to its high temperature and chemical resistance, and can be used multiple times. The EPDM material is a more economical material with reduced heat resistance and is also reusable. Our line of easy pull masking caps are also available in silicone and EPDM and are designed to provide a positive seal, while the wide flange allows for easy removal. High temperature vinyl caps are an economical solution for one time uses. They provide excellent chemical resistance and are used for a variety of applications. These are available in a standard cap design, or with a finger pull tab for easy removal. The tapered paper masking caps completes this product range. These environmentally friendly masking solution is recyclable and made of a blend of post consumer and virgin materials. The paper does not promote condensation and is an economical solution compared to rubber and silicone products. These paper caps are typically used in painting and powder coating applications. Keep in mind that paper is hydroscopic, meaning there will be minor dimensional variations with changes in humidity.
