Wyckomar UV Replacement Quartz Dome RQD-269 for UV-1

Replacement Quartz Dome RQD-269 for the UV-1

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.
