Silicone Rubber Caps are ideal for protecting and masking parts undergoing painting, plating, powder coating, anodizing, abrasive chemical processing, or exposure to high temperatures up to 600 degrees F (316 degrees C). Molded from a specifically formulated grade of silicone rubber, these caps contain no coloring agents which could bleed under high temperatures. SRC Series Silicone Rubber Caps are especially suited for covering studs, tube ends, and other projections.
