Product Description

The WATERCO W12612 is a replacement O-ring designed for use with the V-band lid assembly on MultiCyclone and HRV Series filter systems. This sealing component maintains a pressure-tight connection at the filter lid, preventing leaks during normal system operation. Pool and water treatment service technicians install this part as a routine maintenance item whenever the lid seal shows signs of wear, deformation, or bypass leakage. Keeping a correct-spec O-ring seated in the V-band lid groove is essential for system integrity and sustained filtration performance.

This O-ring is used in pool and water treatment filtration applications where WATERCO MultiCyclone or HRV Series filter units are installed. It is a common wear item serviced during seasonal startups, equipment inspections, or any time the filter lid is removed for internal access. Proper sealing at the lid is critical to maintaining system pressure and preventing water loss at the filter housing.

Installation Notes

Installation should be performed by a qualified pool or water treatment technician. Before servicing the filter lid, shut off the system pump and relieve any pressure in the filter housing per standard service procedure. Inspect the O-ring groove for debris or damage before seating the new ring, and avoid using petroleum-based lubricants on EPDM or rubber seals unless the lubricant is specifically rated for pool system components.
