Eshopps Eclipse Overflow Box Replacement Gaskets
Eshopps Eclipse Overflow Box Replacement Gaskets are the market leader for Eclipse-style overflow systems because they are OEM-fit, engineered to match the box geometry precisely and minimize the risk of overflow leaks. They are more specialized (and often priced competitively) than universal bulkhead kits like Lifegard’s, offering superior ease-of-installation for Eclipse owners but less cross-compatibility for other sump plumbing needs.

Sicce Syncra Pump Replacement O-Ring Kit
The Sicce Syncra Pump Replacement O-Ring Kit is purpose-built for pump internals and is the technical leader when sealing rotating shafts and pump housings, offering materials and tolerances specified by the OEM to withstand heat and continuous operation. Unlike bulkhead or overflow gaskets, Sicce’s kit addresses dynamic sealing challenges inside pumps, reducing the risk of motor-water intrusion and often delivering longer service life that justifies its OEM pricing for pump maintenance.
