Prevent leaks and maintain proper filter system performance with the Universal 2-360 N70 Filter Lid O-Ring. This high-quality replacement sealing gasket is designed for select Waterway® cartridge filters, Swim Quip® XLVII filters, and other filtration systems utilizing the popular 805-0360 and 172223 lid O-ring specification.
A properly functioning filter lid O-ring is essential for maintaining a watertight seal between the filter canister and filter lid. Over time, exposure to chemicals, heat, and pressure can cause O-rings to flatten, crack, or become brittle, leading to leaks, pressure loss, and reduced filtration efficiency.
Replacing a worn O-ring is an inexpensive preventative maintenance item that helps ensure proper filtration system operation while protecting pumps and other equipment from air leaks and water loss.

Signs It's Time to Replace Your Filter Lid O-Ring
Replace your O-ring if you notice:
- Water leaking from the filter lid
- Difficulty maintaining filter pressure
- Air entering the filtration system
- Cracks, flattening, or brittleness
- Loss of elasticity
- Evidence of chemical deterioration
Replacing a worn O-ring can often resolve minor leaks immediately and restore proper filter operation.
Installation Tips
- Shut off all pumps and relieve system pressure.
- Remove the filter lid and old O-ring.
- Clean the O-ring groove thoroughly.
- Inspect the sealing surfaces for debris or damage.
- Lightly lubricate the new O-ring with a silicone-based lubricant.
- Reinstall the filter lid and tighten according to manufacturer specifications.
Do not use petroleum-based lubricants, as they can damage rubber O-rings.
Pro Tip
Whenever replacing a cartridge filter or performing seasonal maintenance, inspect the filter lid O-ring. Replacing an aging O-ring before it fails can help prevent leaks, unnecessary service calls, and equipment downtime.
