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 pools. Air Jet Valve Cover: The air jet valve is made of plastic material, durable and resistant to damage. The air jet valve cap is made of black rubber, 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 Tips: Product may vary slightly between batches.
