Washing machines don’t always require a water hammer arrestor, but if your appliance causes pipe vibration or banging, an inline arrester with hose fittings can help; if that doesn’t solve the problem, partially closing the supply valves can reduce peak flow. Most washing machine hoses in the U.S. use ¾-inch NPT fittings with a rubber washer for a leak-free seal. Our Plastic 2 Way Tap for Washing Machines is built from durable ABS with a reliable POM disc cartridge, designed for single-hole, wall-mounted installation and featuring an easy-to-use ABS handle. Finished in white or customized colors, it comes with a one-year guarantee and is suitable for villas, apartments, and a variety of residential applications. We also offer a complete range of plastic faucets, shower sets with shelves, and other bathroom and kitchen products, all designed for easy installation and long-term performance. We welcome your inquiries anytime.
