Wyckomar UV Replacement Quartz Dome RQD-895 for UV-700 and UV-1200

Replacement Quartz Dome RQD-895 for the UV-700 and the UV-1200

The Wyckomar Quartz Dome together with the Oring keep the water sealed inside the UV reaction chamber and away from the UV lamp, allowing the UV rays to irradiate the water column flowing through the chamber. 

The dome comes with a spring inside to prevent the UV lamp from cracking the quartz upon insertion.
