GMX600NM Noryl Valve Flange Clamp – for Hayward Pro Series Sand Filters – Optimal Tightening and Fixing

This is a high-quality replacement part for Hayward Pro Series sand filters: a GMX600NM flanged hose clamp made of Noryl. Noryl is a modified polyphenylene oxide (PPO) resin, known for its excellent dimensional stability, high strength, and good chemical resistance, making it ideal for manufacturing pool equipment components subject to pressure and chemical corrosion. This flanged hose clamp is an essential fastener that secures the multiport valve (control valve) of the sand filter to the top of the tank.

On Hayward Pro Series sand filters, the multiport valve is not screwed directly onto the tank. A large flanged hose clamp securely holds the valve body flange to the tank flange, ensuring a watertight seal. The GMX600NM flanged hose clamp is this crucial locking device.

It must exert sufficient and uniform clamping force to resist the internal water pressure that tends to lift the valve body, thus ensuring a reliable seal. If the original flanges rust, deform, or break due to prolonged exposure to the elements, this will result in a significant leak at the connection between the check valve and the tank, or even a serious accident such as the valve detaching under high pressure. Replacing the flanges with GMX600NM Noryl flanges is a durable, high-quality solution that guarantees the safe and leak-proof operation of your Hayward Pro Series sand filters.
