Replacement Quartz Glass QG017 – 695 × 25 mm for 40 and 75W amalgam UV-C Lamps
The QG017 is a high-purity quartz glass sleeve designed to protect UV-C lamps in pool, pond and water treatment systems. Quartz glass transmits UV-C radiation (254 nm) with minimal absorption, keeping the lamp’s germicidal output at maximum effectiveness while isolating it from direct water contact.
When to Replace
Quartz glass should be replaced whenever it is cracked, visibly cloudy or shows mineral scaling that cannot be removed by cleaning. A degraded quartz sleeve can block up to 50% of UV-C output, dramatically reducing water disinfection performance. Replace the quartz sleeve at the same time as the UV-C lamp for best results.
Compatible Systems
The QG017 (695 × 25 mm) is sized to fit Blue Lagoon VSC UV-C units rated at 40 and 75W amalgam. Always check the sleeve dimensions and end-cap type against your unit’s specifications before ordering.
