Silicone gaskets give you have an excellent seal against the weather. They are not affected by moisture and humid conditions. Also, ultraviolet light doesn’t weaken silicone, and it will not shrink over time.


Neoprene is the brand name for polychloroprene. It was developed by DuPont as a synthetic rubber. In fact, it’s superior to real rubber in many ways. It’s more durable and doesn’t crack easily under stress. A custom neoprene gasket can withstand temperatures as high as 248 degrees Fahrenheit and as low as -40 degrees Fahrenheit. Polychloroprene has good water resistance and is resistant to chemicals and oils. In fact, it has been used for many years in the soles for work shoes and boots.
