Harman Corporation's Silicone Flange Caps

For any job that requires painting around a threaded stud or protrusion, its important to use one of Harman Corporation's silicone flange caps. The caps will slip over each stud to ensure protection against unwanted paint and high temperatures to give you the cleanest finish. The Harman Corporation understands the complexity of powder-coating, e-coating, and plating. This is why our silicone flange caps feature a larger head (to cover more grounding area) and internal gripping to ensure the cap remains stable.

Our silicone flange caps can withstand temperatures of up to 600ºF/315ºC so you’ll never have to worry about excess pressure building up. The Harman Corporation silicone flange caps feature a vented design created to let air filter out in the case of any added pressure.

The internal gripping is something that can often be overlooked but the truth is: nobody wishes to experience cap slippage when high temp painting. This can lower the quality of your work or worse, require a re-coat. Always secure your caps before painting and be sure your caps have some type of slip protection such as the Harman Corporation's silicone flange caps internal gripping.
