Our purpose is to be the global leader in providing users with safe access to drinking water by offering the best solutions in connection systems , thanks to our commitment to innovation and excellence in service , which, with the contribution of our partners, make us the preferred brand of installers and component manufacturers .
We want to develop this mission based on the values that define us. We are experts, reliable, honest, responsible and committed to diversity and equal opportunities.
For this purpose, we have developed a management system based on:
Improve customer satisfaction.
To improve the effectiveness and efficiency of our processes through the promotion of excellence, continuous improvement and under a continuous perspective of risk assessment and prevention, minimizing waste and the consumption of natural resources.
To promote innovation in both products and processes, fostering knowledge, scientific exchange and development applied to our customers.
Satisfying stakeholders: protecting the environment, customers, certification bodies, suppliers and TUCAI personnel.
Minimize risks to the safety and health of your employees. Promote consultation and participation of workers or their representatives.
Ensuring compliance with applicable legal and regulatory requirements, as well as preventing pollution and climate change, reducing the company's carbon footprint.
Management is committed to provide the necessary resources to achieve the objectives set in our Management System. It is also committed to ensuring that the Policy is understood and implemented, involving all levels of the organization.
Management System Compliance
- Tucai Group is proactive in order to deliver a product in compliance with legal and customer requirements; such as REACh, RoHS, PFAS, POP, TSCA, California 65 or the Waste Framework Directive.
- We regularly monitor changes in the market related to these issues using various sources such as government websites, consulting firms and suppliers.
- The Tucai Group is committed to the care and protection of people and the sustainability of the environment.
- Obtained ISO 14001 (Environmental Management System) and ISO 45001 (Occupational Health and Safety Management) certification at the production sites in Bulgaria and China, as well as ISO 9001 (Quality Management) certification at all 3 factories.
- The TUCAI group calculates the carbon footprint of its organization (as of 2021) and defines improvements to reduce this footprint. TUCAI also works on the carbon footprint of products in order to bring friendly and safe products to the market.
- We are registered in ECOVADIS
International certifications
TUCAI products are certified by different organizations worldwide.
These quality marks demonstrate compliance with the main technical, health and functional requirements established in contractual agreements and/or are part of legal obligations in certain countries.
They are a differentiating element that gives our customers the peace of mind that they have purchased a reliable product.
Regulatory framework in Spain
In Spain there is also a mandatory regulatory framework: the Technical Building Code (CTE). A set of regulations governing the construction of buildings in Spain since 2006.
It establishes the basic safety and habitability requirements for buildings, and therefore, our products, both flexible and valves, must comply with the requirements of the CTE.
Tucai in-house testing laboratories
- TUCAI has three fully equipped laboratories in its plants in Spain, Bulgaria and China, where, in addition to all production controls, the following are carried out:
- Mechanical tests required by certifying agencies
- Research and development trials
- Specific tests required by customer….etc.
- TUCAI laboratories are open to customers in order to jointly achieve all the required objectives.
- Experience, Quality, Customization, …. are in our DNA.
- We develop our laboratory activity for different industrial sectors, but always focused on the requirements of different types of markets, certifying bodies and customers.

Stress corrosion testing
According to product standard EN 13618, brass fittings, including bushings, shall be free from internal tensile forces and must withstand mercurous nitrate and ammonium tests.
After the test, the rods should show no traces of cracking even when viewed under microscope magnification 10 times.
Tightening torque resistance of the fasteners
According to product standard EN13618, male fittings and swivel nuts, according to their DN, must withstand a tightening torque in N according to table 6.
After the test, the rods should show no traces of cracking even when viewed under microscope magnification 10 times.
Bending strength
According to product standard EN13618, fittings according to their DN, must withstand bending tightening stresses according to table 7.
After the test, the rods should show no traces of cracking even when viewed under microscope magnification 10 times.
Flow rate
According to product standard EN13618.
Three samples of 100mm will be taken from the DN that needs to be checked. of length, and in a straight position the flow rate will be checked at a pressure of 3L/min according to table 8 of the standard.
TABLE 8
| Nominal size | Minimum flow rate (l/min) | Minimum gauge diameter (mm) |
| DN 6 | 16 | - |
| DN 8 | 28 | - |
| DN 10 | 45 | - |
| DN 13 | 60 | - |
| DN 15 | - | 12,5 |
| DN 18 | - | 15 |
| DN 20 | - | 17 |
| DN 25 | - | 20 |
Tensile strength
According to product standard EN13618.
Three samples of the DNA that needs to be checked will be taken and the following will be performed:
- Pre-aging of the tubes for 1 week (168h) at 90ºC and with static water pressure inside the tubes of 1.2Mpa).
- Properly the tensile test, according to table 9 of the standard, which relates the tensile force in N, with the DN to be tested.
During and after these tests, the flexible assembly should not show any leaks or other damage.
TABLE 9
| Nominal size | Tensile stress |
| DN 6 | 600 |
| DN 8 | 600 |
| DN 10 | 800 |
