POM Material Excellence: Bolts and nuts are made of corrosion-resistant POM (polyoxymethylene), ensuring no rust, breakage, or deformation under high torque.
EPDM Rubber Seals : Black EPDM (ethylene propylene diene monomer) gaskets provide 100% waterproofing, compatible with 95% of toilet tank designs.
Chemical Resistance : Components withstand exposure to cleaning agents (pH 3-12) without degradation.
Load-Bearing Capacity : POM bolts support up to 50kg static load, exceeding ASTM F468 industrial standards.
Easy Installation
Tool-Free Assembly : Butterfly nuts enable hand-tightening without wrenches, reducing installation time to <10 minutes.
Dual-Lock System : Foam gaskets + lock nuts create a vibration-resistant seal (tested at 2000 RPM).
Universal Sizing : 3/8" diameter bolts with 2.5" length fit all major brands (Kohler, TOTO, American Standard).
Error-Proof Design : Color-coded nuts (black for tank, silver for base) prevent mismatched installation.
Perfect Protection
Zero-Displacement Guarantee : 2" extended lock nuts distribute pressure evenly, eliminating tank wobble (≤0.3mm movement under 50N force).
Pressure-Tested Seals : Withstands 1.5x max municipal water pressure (150 PSI) without leakage.
Corrosion Barrier : Rubber gaskets isolate metal components from moisture, reducing valve failure risk by 70%.
Thermal Stability : Operates flawlessly in -40°F to 212°F environments (verified via MIL-STD-810G testing).
