The seat material directly impacts sealing performance, chemical compatibility, and durability. PTFE Teflon seats, featured in the Harris 247-50-CR and Harris 9235-350-540, offer excellent chemical resistance and longevity. Neoprene seats, like in the Harris 447NC-200, are ideal for general-purpose applications where flexibility is beneficial. There are also specialized materials like PCTFE (Kel-F), as in the Harris HP8700-1500-540, for high purity and high-pressure uses. With several seat material options, you can match the regulator to your application’s demands.
