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
Q1: What is the purpose of a copper P-trap?
A copper P-trap creates a liquid seal that prevents sewer gases or refrigerant backflow while allowing wastewater or condensate to drain away.
Q2: Can copper P-traps be used in cold storage systems?
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.
Q3: How are copper P-traps connected?
They can be joined to copper piping using welding (brazing) or press fittings, both ensuring a secure and leak-proof connection.
Q4: Are custom sizes available?
Yes. We offer standard and customized diameters, lengths, and wall thicknesses to meet specific plumbing and HVAC/R project requirements.
Q5: Why choose copper material?
Copper is highly durable, resistant to corrosion, and has excellent thermal conductivity, making it suitable for demanding plumbing, HVAC, refrigeration, and cold storage applications.
