Flexible CSST Piping
Be Flexible. Save Time.


Flexible Corrugated Stainless Steel Tubing (CSST)
CSST is a flexible piping made from high-grade stainless steel SS304 or SS316. Its corrugated design allows it to bend and curve without the need for excessive fittings or joints, making it a smart alternative to rigid piping systems.
The flexible, corrugated design makes it easy and safe to bend, facilitating installation in tight spaces and around obstacles without the need for multiple fittings. CSST is also capable of absorbing movement from vibration, thermal expansion, freezing, misalignment, and repeated motion, making it ideal for dynamic environments.
Where Is CSST Used?
Thanks to its versatility, CSST is used in a variety of applications:
- Hot and Cold water pipelines (including food grade)
- Water heaters
- Radiant floor heating systems
- HVAC connections
- Solar thermal systems
- Fire suppression system
- Plumbing fixtures
- Machinery field
Key Benefits of CSST Over Conventional Piping
1. Faster, Easier Installation
One of CSST’s biggest advantages is how much it simplifies installation. Because it bends around corners and obstacles with ease, there’s less need for elbow joints and connectors. This not only speeds up the process but also cuts down on labor costs, fitting costs, and potential points of failure.
2. Improved Leak Resistance
Fewer joints mean fewer opportunities for leaks. CSST systems are often more reliable because the tubing runs in longer, continuous lengths compared to traditional systems that require multiple connected segments.
3. Excellent Durability & Corrosion Resistance
Made of stainless steel, CSST naturally resists rust and corrosion, making it ideal for environments exposed to moisture or chemical elements. Unlike traditional copper, iron, or galvanized pipes that can degrade over time, CSST maintains its structural integrity for decades.
4. Seismic Flexibility & Safety
In earthquake-prone areas, CSST offers a critical advantage. Its flexibility allows it to absorb movement and vibrations, helping to prevent leaks or pipe rupture during seismic events.
5. Energy Efficiency in Heating Systems
CSST has a higher thermal conductivity compared to plastic-based alternatives like PEX. This makes it especially beneficial in radiant floor heating and similar systems where heat transfer efficiency is key.
6. Eco-Friendly and Sustainable
Beyond performance, CSST is also an environmentally responsible choice. It’s fully recyclable, and the production process for stainless steel has a lower environmental impact than many other pipe materials. With no harmful emissions during installation or use, it’s a greener option from start to finish.
7. Freeze Resistance
CSST offers excellent freeze resistance due to its ability to expand slightly and flex under pressure. Unlike rigid piping materials that are prone to cracking or bursting when water inside them freezes, CSST’s flexible design allows it to better withstand the stress caused by expanding ice. This makes it a safer and more reliable option in colder climates or unheated areas, where freezing temperatures could otherwise lead to costly damage and repairs.
Why Flexible Corrugated Stainless Steel Tubing (CSST) Is Shaping the Future of Piping Systems
As construction practices evolve and demand increases for more efficient, durable, and safe piping systems, Flexible Corrugated Stainless Steel Tubing (CSST) is quickly becoming the go-to choice across residential, commercial, and industrial projects. Known for its adaptability and strength, CSST offers a host of benefits over conventional materials like black iron, copper, and even PEX.


CSST Installation
Installation of the CSST is a quick and straightforward process that significantly reduces both labor time and overall costs.

Flexible Corrugated Stainless Steel Tubing is more than just a modern alternative — it’s a leap forward in how we think about piping. With advantages in safety, durability, ease of installation, and environmental sustainability, it’s no surprise that CSST is becoming a preferred solution in a wide range of building and infrastructure projects.
