Our copper P-traps are high-quality pipe fittings designed to form a reliable water or liquid seal, preventing gas backflow and ensuring smooth drainage. Made from premium copper, they feature excellent corrosion resistance, thermal conductivity, and durability, making them suitable for a wide range of applications.
Key Features:
• Function: Creates a liquid seal to block sewer gases or refrigerant backflow while allowing fluid drainage.
• Material: High-grade copper for strength, corrosion resistance, and excellent heat transfer.
• Connection: Joined by welding (brazing) or press fitting, ensuring secure and leak-proof installation.
• Applications:
• Plumbing and drainage systems
• HVAC air-conditioning devices
• Refrigeration pipelines
• Heat pump water heaters
• Cold storage systems: Prevent refrigerant/oil backflow in vertical piping, protect compressors, and ensure sealing integrity

FAQ
A copper P-trap creates a liquid seal that prevents sewer gases or refrigerant backflow while allowing wastewater or condensate to drain away.
Yes. In refrigeration and cold storage systems, copper P-traps are installed in vertical pipelines to prevent refrigerant and oil from flowing backward, protecting the compressor and improving system efficiency.
They can be joined to copper piping using welding (brazing) or press fittings, both ensuring a secure and leak-proof connection.
Yes. We offer standard and customized diameters, lengths, and wall thicknesses to meet specific plumbing and HVAC/R project requirements.
Copper is highly durable, resistant to corrosion, and has excellent thermal conductivity, making it suitable for demanding plumbing, HVAC, refrigeration, and cold storage applications.
