Shanghai, May 28, 2025 — TOBO Industrial (Shanghai) Co., Ltd., a global manufacturer and supplier of premium metal pipe fittings, has launched a new line of Factory Price Copper Straight Couplings tailored specifically for plumbing and HVAC air conditioning systems. Designed to deliver optimal performance at an affordable price point, this latest offering reflects TOBO’s ongoing commitment to supporting efficient, high-quality infrastructure for commercial, industrial, and residential environments.
With the HVAC industry experiencing unprecedented growth due to rising demand for energy-efficient climate control systems, TOBO’s new copper straight coupling meets the moment—offering contractors, engineers, and project managers a durable, cost-effective solution for seamless pipe connectivity.
Built for Durability and Versatility
TOBO’s copper straight coupling is constructed using high-purity copper—renowned for its corrosion resistance, thermal conductivity, and reliability under pressure. This fitting is engineered for use with hard and soft copper tubing, allowing it to adapt across a variety of HVAC applications, including:
Air conditioner refrigerant lines
Water supply and distribution systems
Heat pump systems
Chilled water loops
Commercial ventilation units
Its straight design facilitates in-line connections between two pipes of the same diameter, ensuring a tight seal and efficient flow path without turbulence or flow loss.
Why Copper Remains the Gold Standard
Copper has long been the material of choice in HVAC and plumbing applications due to its unique combination of physical and chemical properties:
Thermal Conductivity: Copper transfers heat more efficiently than other commonly used metals, making it ideal for refrigerant and water systems where energy efficiency is key.
Corrosion Resistance: With a natural oxide layer that resists internal and external corrosion, copper provides a longer service life compared to steel or plastic fittings.
Pressure and Temperature Tolerance: Copper can handle high-pressure refrigerants and fluctuating temperatures without deforming or degrading.
Ease of Installation: The material is soft enough to machine and form, allowing for easy cutting, flaring, brazing, and soldering during installation.
TOBO’s couplings take full advantage of these properties, ensuring long-term performance even in demanding HVAC environments.
Manufactured to International Standards
All TOBO copper couplings are produced under strict quality controls in compliance with international standards such as ASTM B280, EN 1254, and ANSI/NSF 61. This ensures each unit maintains consistent internal diameter, wall thickness, and dimensional tolerances required for high-pressure HVAC applications.
The couplings are available in a wide range of sizes—typically from 1/4 inch to 2-1/8 inches—ensuring compatibility with standard HVAC tubing dimensions used in North America, Europe, the Middle East, and Asia.
Seamless Integration for HVAC Systems
One of the key features of TOBO’s copper straight coupling is its perfect fit and smooth bore. This reduces flow resistance and improves system efficiency. The fittings are designed to be brazed or soldered, forming a permanent, leak-free joint when properly installed.
When used in air conditioning and refrigeration systems, the coupling helps maintain refrigerant flow integrity, contributing to:
Lower energy consumption
Stable compressor operation
Reduced refrigerant leakage
Quieter system performance
This makes TOBO’s couplings a preferred choice among HVAC professionals looking to balance performance and cost-efficiency.
Competitive Factory Pricing
With in-house production capabilities and bulk material sourcing, TOBO is able to offer these high-quality copper fittings at factory-direct prices. This is a significant advantage for wholesalers, OEMs, and large-scale project developers who seek:
Lower cost per unit
Consistent product availability
Customized packaging and branding
Fast lead times for international shipments
By working directly with TOBO, clients benefit from reduced overhead costs, better quality assurance, and responsive technical support.
Applications Across Markets
The TOBO copper straight coupling is suitable for a variety of applications beyond HVAC systems, including:
Residential plumbing: Hot and cold water lines, underfloor heating
Commercial buildings: Chillers, rooftop units, central air distribution
Industrial cooling systems: Process cooling loops, air compressors
Renewable energy: Heat exchangers in solar and geothermal systems
Marine HVAC: Compact air conditioning systems in boats and offshore facilities
Its versatility and reliability make it a staple in both new installations and retrofit projects worldwide.
Environmental and Health Compliance
