When the air jet valve cap is used alone with the inlet nozzle, it can block water flow and help prevent leakage in the pool. When used together with the air jet valve, it helps prevent air entry. This replacement part is compatible with above ground pool air jet valve covers. Construction: The air jet valve is primarily made of durable plastic material, resistant to damage. The air jet valve cap is made of black rubber, which is soft, corrosion-resistant, and provides good sealing performance. The air nozzle at the entrance of the above ground swimming pool allows circulating water to pass through. Color: As shown Material: Plastic Note: Product design may be updated periodically.
