The Oase Quartz Glass Sleeve D44 × 429 mm with Rim is a genuine Oase replacement quartz tube designed for use in compatible FiltoClear UVC units, such as the FiltoClear 19000 and similar models.

This official Oase spare part serves as the protective quartz sleeve that surrounds the UVC lamp. It’s a cylindrical quartz glass tube with a flared/rimmed end that helps create a secure seal in the UVC chamber and protects the lamp from water exposure while ensuring optimal UV transmission and performance.
