Looking for Polypropylene 3/8-inch air-operated diaphragm pumps from All-Flo™? If you prefer a non-metallic wetted path, Polypropylene is a versatile option to consider for compatibility-driven specs. A three-eighths-inch port size is a nice fit when you want controlled transfer and easy integration into smaller lines and fittings. This combination pairs a Polypropylene wetted path with a 3/8-inch connection size, two of the biggest factors when you’re choosing an AODD pump. Compare the available models below to find the best fit for your application. If you’re replacing an existing unit, double-check your connection size and specs so the swap is smooth.
