Replacement OEM Part Number: 12363 12373 Compact air jet valve and rubber cap designed as a direct replacement for a wide range of above ground pool fittings. The assembly controls air entry and water flow at the inlet nozzle, preventing leaks and helping maintain consistent system operation. Key benefits Controls air and water flow precisely: the valve admits air into the adapter to pressurize and eject water when needed, and the cap blocks unwanted water flow when used alone. Prevents leaks and air intrusion: use the cap by itself to stop water leakage at the inlet, or combine cap and valve to prevent air entry into the circulation system. Durable materials: valve body made of sturdy plastic for long service life; black rubber cap is flexible, corrosion resistant, and provides reliable sealing. Easy replacement: sold as a single valve and cap set to restore proper function without replacing the entire fitting. Function and performance Air passes through the jet valve into the adapter to generate pressure for water ejection. Caponly configuration seals the inlet nozzle to block water flow and reduce leakage. Valvepluscap configuration prevents unwanted air from entering the pool circulation system, helping maintain stable operation. Compatibility Fits the following models: 26165EH, 26167EH, 26175EH, 26183MW, 26191CA, 26191EH, 26193EH, 26301T, 26303EH, 26309EH, 26321EH, 26323CA, 26323EH, 26331CA, 26331EH, 26335EH, 26337EH, 26341W, 26343EH, 26345W, 26351EH, 26351W, 26361CA, 26361EH, 26361W, 26365EH, 26371CA, 26371EH, 26375EH, 26381EH, 26719MW, 26719W, 26733EH, 26735EH Materials and package Valve body: durable plastic Cap: black rubber, soft and sealing Package includes 1 air jet valve and 1 black air jet valve cap. No installation instructions included. Practical use scenarios a cracked or leaking jet fitting on an above ground pool to stop water loss and restore proper flow. Install the cap alone during winterization or temporary shutdown to block water from entering the inlet nozzle. Use the valve and cap together after maintenance to prevent air from entering the circulation system and maintain stable pump performance. Notes Confirm compatibility with your model number before installation. Designed for use with the listed above ground pool fittings and adapters.
