Replacement O-Ring for King Keg 4" Caps
Replace a worn cap seal with this King Keg 4" O-ring. A useful spare for maintaining the seal between your barrel and its cap, without replacing the complete cap assembly.
When to Replace Your O-Ring
Check the cap seal when maintaining your pressure barrel. If the existing O-ring is damaged or no longer sits correctly, replace it before putting the barrel back into use.
How to Fit
- Fully release the barrel pressure before removing the cap.
- Remove the old O-ring and clean the seating area.
- Fit the replacement evenly, checking that it is seated without twists.
- Refit the cap and check the seal before use.
For help removing and refitting the cap, see the Plastic Spanner for King Keg 4" Caps.
