Secure a leak-free strainer lid on your AquaStar Pipeline pump with the AP1101 Locking Ring, Cover, and O-Ring Assembly, a factory OEM kit built for the PLP150S (1.5 HP) and PLP300S (3 HP) variable-speed models. This three-piece set locks the transparent lid firmly onto the strainer housing, forming a sealed enclosure that prevents air infiltration and water loss. The included EPDM O-Ring (#439) provides outstanding resistance to pool chemicals, ultraviolet light, and mechanical wear, ensuring the seal stays intact through heavy use.

Whether you are performing seasonal startup maintenance or replacing a cracked lid mid-season, the AP1101 makes the job straightforward. The locking ring threads on smoothly, the clear cover lets you monitor basket fill level at a glance, and a lightly lubricated O-ring keeps the assembly airtight. Maintaining this seal is critical for holding pump prime, preventing cavitation, and delivering consistent water flow throughout your pool system.

Key Benefits

• Genuine OEM AquaStar Fit: Precision-engineered for PLP150 1.5 HP and PLP300 3 HP variable-speed Pipeline pumps, guaranteeing exact thread engagement and sealing geometry.
• Airtight, Drip-Free Assembly: The locking ring, transparent cover, and EPDM O-Ring (#439) combine to create a sealed barrier that blocks air leaks and eliminates water seepage.
• Resilient, Weather-Proof Materials: Components are built to resist prolonged UV exposure, chlorine-based chemicals, and the physical wear of repeated lid removal and reinstallation.
• Convenient Basket Access: The quick-release locking ring design allows fast lid removal for strainer basket inspection and cleaning, cutting downtime to a minimum.
• Maintains Pump Prime Integrity: A properly lubricated O-ring seals out air, helping the pump hold prime and deliver steady, efficient water circulation year after year.
