If your Jandy cartridge filter's pressure gauge port is cracked or leaking, this brass adapter is your fix. It replaces the original plastic stem on CS100, CS150, CS200, CS250, CJ200, and CJ250 models. Made from solid brass, it's way more durable and threads in smoothly. Comes with a fresh rubber O-ring for a tight seal. Lets you attach your pressure gauge and also includes an air relief valve to bleed off pressure safely. Important: before installing, make sure the pump is off and pressure is released. Fits standard gauges. Keep your filter running smoothly without replacing the whole tank. Simple upgrade, reliable performance.
