Products Description
O Ring Seal – Square Ring Replacement
This o ring seal is designed for pool and spa systems. It helps seal parts together to prevent leaks. A strong seal maintains stable pressure and improves water flow during operation.
This is an aftermarket rubber o-ring seal made to match compatible systems. It performs well in high-flow, high-pressure environments where a tight seal is required.
Compatible Pool and Spa Systems
This o-ring seal fits selected Triton® C-3 pool and spa filters, including TR100C and TR140C-style units. It also works with selected waterfall pumps and Challenger®-style spa pumps.
Always check the seal size and surface before installation to ensure a proper fit.
Square Design for Better Sealing
The square shape provides a wider sealing surface than standard round seals. This allows even compression under pressure and helps reduce the risk of leaks.
The stable design supports long-term performance in demanding pool and spa systems.
