Precision-Engineered Iron Water Stopper for Superior Concrete Formwork Seals

High-density cast iron construction ensures unmatched durability and corrosion resistance in demanding construction environments. Designed specifically for plastic formwork tie rod systems, this stopper creates perfect watertight seals during concrete casting with precision CNC-machined threading.

The reinforced hexagonal base allows secure wrench tightening while preventing deformation under high-pressure pours. Ideal for bridge decks, foundation walls, and tilt-up concrete panels where leakage prevention is critical.

Features industrial-grade zinc plating that withstands alkaline exposure from wet concrete and harsh weather conditions. Compatible with all major formwork brands including PERI, Doka, and MEVA systems. Ships in bulk quantities with wholesale pricing for large-scale construction projects.

Optimized weight-to-strength ratio reduces labor fatigue during installation while maintaining structural integrity. Meets ASTM A48 Class 30 standards for cast iron construction components. Essential for contractors requiring reliable, reusable formwork accessories.

Packaged in heavy-duty moisture-proof cartons with individual anti-rust coating for long-term storage. Minimum order quantities available for cost-sensitive bulk buyers. Global shipping with door-to-door logistics support for job site deliveries.
