Viqua’s quartz sleeves are made of 100% fused silica, which lends to the sleeve’s high transmittance. A high transmittance is important as the UV light must travel through the sleeve to reach the water. There are various quartz sleeve designs depending on the system they are used in. The QS-212 is an open-ended quartz sleeve used in the Silver series. All replacement sleeves are shipped with two O-rings.
