Water plugs (freeze plugs) protect engines from freeze damage and seal casting holes. Common materials include copper, brass, stainless steel, and zinc-plated iron.
Key Applications:
Automotive/Truck Engines: Installed in engine blocks to prevent cracking from frozen coolant.
Washing Machines & Pumps: Seal water passages in drums and industrial pumps.
Why Buyers Care: International buyers (especially in EU/US) prioritize:
Material Quality: Stainless steel for corrosion resistance; brass for cost-effectiveness.
Compliance: Certifications (ISO, ASTM) and RoHS compliance are critical.
Reliability: Failure can cause severe engine damage – buyers demand tested products with performance data.
