Description
Replacement Quartz Sleeve O-Ring Gasket for Jebao CW-36, CW-55, NPU-36 & NPU-55
Refresh the quartz sleeve seal in your compatible Jebao UV unit with this replacement sleeve O-ring gasket. This listing includes one sleeve O-ring only. Compare the ring and its installation position with the photos before ordering.
Product Highlights
- MODEL COMPATIBILITY: Fits the quartz sleeve sealing position on Jebao CW-36, CW-55, NPU-36 and NPU-55 units.
- SLEEVE-SPECIFIC FIT: Intended for the quartz sleeve seal. This is not the larger ballast/head O-ring.
- SEAL MAINTENANCE: Replaces a worn, flattened or damaged sleeve gasket to help maintain a proper seal when correctly fitted.
- CHECK BEFORE ORDERING: Match your unit model, existing ring and sealing groove to the product photo. Ballast and sleeve O-rings serve different positions.
- SINGLE REPLACEMENT GASKET: Includes one sleeve O-ring. Quartz sleeve, UV lamp, ballast, housing and other parts are not included.
Installation
Disconnect power before servicing. Handle the quartz sleeve carefully, clean the sealing surfaces, and seat the ring evenly without twisting or pinching. Check the assembled unit for leaks before returning it to use. A new gasket will not repair cracked glass or a damaged housing.
