Performance
Wide Temperature Resistance: Operates reliably in temperatures ranging from -60°C to 230°C (special grades up to 260°C), suitable for hot water, steam, and cold fluid systems.
Leak-Proof Sealing: The cup-shaped design creates a tight, pressure-resistant seal around pipe ends, preventing fluid or gas leakage.
Chemical Compatibility: Resists water, steam, alcohols, and mild chemicals, making it ideal for plumbing, HVAC, and general industrial use (not recommended for petroleum-based oils or strong solvents).
Low Compression Set: Exhibits minimal permanent deformation under sustained compression, ensuring consistent sealing performance over extended service life.
Easy Installation & Removal: Flexible silicone material allows for quick installation and removal without tools, simplifying maintenance.
Customizable Design: Available in various sizes to match standard pipe diameters, with custom colors and hardness options.
Application
· Plumbing & Piping Systems: Used as end caps for PVC, PEX, and metal pipes to seal unused ends and prevent leaks in residential and commercial plumbing.
· HVAC Systems: Seals pipe ends in heating, ventilation, and air conditioning systems, withstanding temperature fluctuations and moisture.
· Industrial Piping: Ideal for process piping in chemical, pharmaceutical, and food processing plants, providing chemical resistance and hygienic sealing.
· Automotive & Marine: Seals fluid lines and exhaust pipes, resisting high temperatures and weathering in automotive and marine applications.
· Temporary Sealing: Used for temporary sealing during pipe maintenance, repairs, or system testing.
