A high transmittance is important as the UV light must travel through the sleeve to get to the water. There are a variety of quartz sleeve designs, depending on the system that they are being used in. The QS-212 is an open ended quartz sleeve which is used in the Silver series. All replacement sleeves are shipped with two o-rings.
