Silicone washer caps are specialised high-temperature masking components designed to protect threaded studs and protrusions during coating processes whilst creating a grounding area at the base. These essential masking solutions combine the functionality of traditional caps with an integrated washer design, eliminating the need for two-stage masking procedures. Manufactured from premium silicone rubber, these caps excel in powder coating, electroplating, anodising, and shot blasting applications across the UK's automotive, aerospace, manufacturing, and metal finishing industries. The primary benefit of silicone washer caps lies in their ability to withstand extreme temperatures up to 315°C whilst maintaining flexibility and providing reliable masking performance. Available in multiple colours including clear, pink, red, yellow, purple, grey, and black, these caps offer excellent visual identification for different sizes, enhancing operational efficiency and reducing application errors. The robust silicone construction ensures reusability across multiple coating cycles, delivering exceptional value and consistent protection for threaded components.
