Shanghai, June 4, 2025 — TOBO Industrial (Shanghai) Co., Ltd., a global manufacturer and exporter of high-performance piping solutions, is proud to announce the launch of its newly enhanced range of 90-degree copper elbow fittings, now available in DN15 to DN200 sizes with customizable options for threaded or socket weld ends. Backed by ISO 9001 certification, these elbows offer a robust, reliable, and corrosion-resistant solution for fluid systems across multiple industries.
The new series is tailored to meet the growing demand for environmentally friendly, thermally efficient, and long-lasting pipeline components in the HVAC, plumbing, water treatment, refrigeration, and industrial equipment sectors. With its advanced production capabilities and deep material expertise, TOBO aims to set a new standard in copper pipe fittings with a balance of customization, compliance, and cost-effectiveness.
Precision Engineering for Fluid Direction Control
The 90-degree copper elbow is one of the most essential components in pipeline systems, enabling fluid redirection at a right angle. Its smooth bend radius ensures minimal turbulence, reduced pressure drop, and optimal flow efficiency, particularly in heating, cooling, and pressurized water systems.
TOBO’s copper elbows are designed with strict dimensional tolerances, ensuring tight fitment with mating pipes and long-term sealing integrity. Whether for small residential plumbing or large-scale industrial fluid transport, the 90-degree elbow plays a vital role in ensuring seamless direction changes without compromising the system’s pressure or efficiency.
Available in DN15 to DN200 — Versatile for Any Project
A standout feature of TOBO’s offering is the broad size range, spanning from DN15 (½ inch) to DN200 (8 inches). This makes the product line suitable for:
Residential and commercial plumbing systems
Municipal water pipelines
HVAC and chiller loops
Industrial process cooling and hot water circulation systems
Fire protection systems and compressed air lines
Each fitting undergoes dimensional inspection to ensure compliance with international standards and customer-specific specifications.
Customizable Ends: Threaded or Socket Weld
Recognizing the diverse needs of customers across different sectors, TOBO offers two end connection types for its 90-degree copper elbows:
Threaded Ends – Designed for quick and secure mechanical connections without welding. These are ideal for modular systems or temporary installations where disassembly may be required.
Socket Weld Ends – Preferred in high-pressure systems and permanent installations. Socket weld ends provide a leak-proof, durable bond, ideal for HVAC piping, boilers, and chemical process applications.
Each end style is manufactured using precision machining tools and adheres to industry-standard thread profiles or socket dimensions, ensuring compatibility with pipes from global manufacturers.
Manufactured with High-Purity Copper Alloy
TOBO utilizes high-grade copper (typically C12200 or equivalent), known for its excellent thermal conductivity, corrosion resistance, and antimicrobial properties. This ensures a product lifespan that exceeds traditional steel or plastic counterparts, especially in applications involving hot water, steam, or mildly acidic fluids.
Copper is a naturally sustainable material that offers biocidal effects against bacteria and biofilm, making these elbows ideal for potable water systems, food-grade piping, and medical fluid applications.
ISO 9001 Certified Production
All TOBO 90-degree copper elbows are manufactured under a rigorous ISO 9001:2015-certified quality management system, which guarantees:
Full traceability of raw materials
Strict in-process inspections
Hydrostatic and pressure testing
Final dimensional verification
Consistent production documentation and batch labeling
The ISO certification ensures global buyers that the products meet stringent quality standards and are suitable for international projects requiring traceable compliance.
Broad Industry Applications
Thanks to their durability, safety, and compatibility, TOBO’s copper elbows are in high demand across a wide range of sectors:
HVAC & Mechanical Engineering: Used for chiller lines, fan coil units, rooftop air handlers, and more
Building Construction: Reliable solutions for hot and cold potable water distribution
Water Treatment Plants: Used in piping networks that handle treated and reclaimed water
Fire Suppression Systems: Non-corrosive elbows ensure integrity in sprinkler piping
Industrial Automation: Ensures precise fluid direction in lubricating and cooling systems
Eco-Friendly and Long-Lasting
Copper is widely regarded as a green building material, thanks to its recyclability, low carbon footprint, and non-toxic nature. TOBO’s elbows are made using energy-efficient production methods, with optional RoHS compliance available upon request for markets that require strict environmental protection measures.
Additionally, copper’s resistance to scale formation means lower maintenance costs and longer intervals between pipe cleaning or replacement, delivering excellent lifetime value to end users.
Packaging, Delivery, and Global Reach
TOBO ensures all elbows are cleaned, capped, and packed in moisture-resistant bags or export-grade cartons/wooden crates, depending on order volume and destination. The company supports:
OEM branding and laser marking
Customer-specific barcoding
Technical data sheets and inspection reports
Fast lead times, typically within 15–20 days for bulk orders
With established logistics partners and overseas warehousing in select regions, TOBO provides timely delivery across North America, Europe, the Middle East, Southeast Asia, and South America.
Commitment to Customer Satisfaction
“Our 90-degree copper elbow fittings are designed not just to meet industry standards but to exceed user expectations in reliability and performance,” said a TOBO company spokesperson. “We offer full customization support, material certification, and end-to-end service for all our global clients — from small mechanical contractors to multinational EPC firms.”
TOBO’s customer-first approach includes responsive sales teams, multilingual technical support, and post-shipment tracking services, ensuring a smooth procurement experience.
Conclusion
TOBO’s newly launched 90-degree copper elbow fittings represent a superior solution for industries that demand precision, durability, and flexibility. With customizable ends, sizes ranging from DN15 to DN200, and ISO 9001-certified quality, these fittings offer an unbeatable combination of performance and value.
As piping infrastructure becomes more advanced and regulation-driven, TOBO stands at the forefront, delivering products that keep systems flowing safely, sustainably, and efficiently — one bend at a time.
