Cronex Close Coupling Plate Kit
The Cronex Close Coupling Plate Kit (Model CXP 5683) is an elite plumbing hardware solution engineered to deliver superior structural stability and long-term protection against moisture damage. As a critical interface in any close-coupled toilet installation, this professional “XL” kit provides the necessary mechanical leverage and sealing capacity to ensure a safe, permanent connection between the water tank and the ceramic bowl.
Constructed for exceptional longevity, the kit utilizes industrial-grade metallic components that offer high tensile strength. The core of the system is the heavy-duty coupling plate, which is precision-contoured to fit standard plumbing infrastructures while resisting the warping often seen in lower-quality composite alternatives. The technical design prioritizes leak-proof performance through its oversized foam gasket, which is specifically formulated to maintain its resilient shape and watertight seal even under constant mechanical pressure and thermal fluctuations.
Cronex’s commitment to quality ensures that the CXP 5683 is a complete, ready-to-use solution, including high-performance mounting bolts and nuts. These fasteners allow for accurate leveling and compression of the tank, significantly reducing the risk of stress fractures on the ceramic surfaces. Whether outfitting a high-traffic commercial facility or completing a residential bathroom restoration, this Cronex kit delivers the professional-tier performance and mechanical fitment required for long-term satisfaction.
