This O-ring kit allows you to eliminate burping the UWL-M52 lens underwater on your TG camera housing. It allows you to pre-seal water from a rinse bucket and eliminates the need to unthread your UWL-M52 lens underwater to burp the lens. This O-ring also allows you to shoot split shots (over/under) with a wet lens on your TG housing. You only need 1 O-ring installed, but our kit includes 5 for backup supply.

No-Burp O-rings are NOT required with M52 Air Lens or QRS Mount System
