Why Replace the Lid O-Ring?

The cover O-ring is a critical sealing component that compresses between the housing body and lid. Over time it can become flattened, hardened or damaged due to repeated servicing, pressure cycles and natural ageing. Replacing the O-ring during routine maintenance helps:

• Prevent water leaks
• Maintain system pressure
• Ensure safe filter housing operation
• Extend the service life of the filter housing
• Reduce unexpected downtime

Installation Advice

Before fitting the new O-ring:

• Clean the O-ring groove and sealing surfaces thoroughly.
• Inspect the housing for dirt or damage.
• Apply a light coating of food-grade silicone lubricant to the O-ring before installation.
• Do not use petroleum-based lubricants, as these may damage EPDM rubber.
• Tighten the housing lid evenly according to the manufacturer's recommendations.
