Aqua One O Ring for Pumphead to suit Aquis 500 700

Aqua One Genuine Replacement Pumphead O-Ring is designed for:

• Aqua One Aquis Canister Filters 500 & 700
•  
• Aqua One Aquis II Canister Filters 550 & 750
•  
• Aqua One Nautilus Canister Filters 600 & 800
•  
• Via Aqua Canister Filters 230 & 300
•  
• JBL Canister Filters CP 120 & 250

The Aqua One Pumphead O-Ring goes around the underside of the Pumphead. When the pumphead clips down onto the filter canister it creates a air tight seal. Over time the O-ring can get dry or cracked which allows water to leak out of the canister filter.
