Blue Lagoon – Quartz Sleeve O-Ring Set (3 pcs) for UV-C Disinfection Systems

This is the genuine Blue Lagoon replacement set of three O-rings designed to seal the quartz sleeve inside select Blue Lagoon UV-C water disinfection units. The O-rings create a watertight seal around the quartz glass, preventing leaks and ensuring the UV-C lamp operates safely and efficiently within the water flow path.

Compatibility

This three-piece O-ring set is the correct replacement part for the following Blue Lagoon UV-C systems: BE01212 (Spa UV-C T5 21 W), BE01213 (Spa UV-C T5 U20 21 W), and BP08752 (Xpert Duplex UV-C). It is also cross-referenced as the quartz sleeve O-ring for several other Blue Lagoon UV-C Tech, Ozone UV-C, and Xpert Compact AOP UV-C models. Always verify your system model before ordering.

Why Genuine Matters

Using the correct OEM O-rings ensures a reliable, leak-free seal on the quartz sleeve — a critical interface where any failure can result in water ingress, UV-C lamp damage, or system downtime. Genuine Blue Lagoon parts are manufactured to the precise dimensions required by the original equipment, giving you confidence during every service interval.

Installation

O-ring replacement is typically carried out during routine maintenance or lamp replacement. After cleaning or swapping the quartz sleeve, the O-ring is fitted back onto the sleeve before the lamp is reconnected and the housing nut is re-tightened by hand. All connections should be hand-tight only — never use tools to force the assembly. If in doubt, consult a qualified pool technician.
