Rothenberger - ROLOCK EPT Expander Set 12-15-18-22mm - 12500

Features of the ROLOCK EPT Set

The Rothenberger ROLOCK EPT Set is a professional expansion system for copper, brass, and aluminum pipes with diameters of 12, 15, 18, and 22 mm. This kit has been specifically designed for plumbers and HVAC technicians who need a reliable tool for creating solderless press connections. The expansion technology allows for the creation of secure and durable connections, significantly reducing installation times compared to traditional methods.

Components included in the set

The complete set, code 12500, includes: an ergonomic expander pliers with a non-slip grip, four interchangeable expansion heads (12, 15, 18, and 22 mm), a practical, durable plastic case for transporting and storing tools, and detailed instructions for optimal use. Each component is made with high-quality materials to ensure strength and durability over time, even under intensive use.

Technical and operational advantages

The ROLOCK EPT system offers numerous advantages over traditional joining methods. Expansion technology allows for creating connections without reducing the pipe's internal diameter, ensuring optimal flow and minimizing pressure losses. The expansion process is fast and precise, allowing installations to be completed in reduced times. The resulting joint is extremely resistant to pressure and mechanical stress, with a perfect seal that eliminates the risk of leaks.

Practical applications

This set is used in numerous professional contexts:

• Installation and maintenance of domestic and industrial plumbing systems
• Creation of heating and air conditioning systems
• Potable water distribution systems
• Professional irrigation systems
• Solar thermal systems
• Gas distribution networks (check local regulations)

Technical specifications

The ROLOCK EPT system is designed to work with soft copper, brass, and aluminum pipes with standard thicknesses. The expander pliers feature a ratchet mechanism that ensures constant and controlled expansion force. The expansion heads are made of special heat-treated steel to ensure wear resistance and dimensional precision. The system complies with European regulations for plumbing and heating systems.

Maintenance and durability

Maintenance of the ROLOCK EPT set is simple, requiring only periodic cleaning and light lubrication of moving parts. The expansion heads are designed for long-lasting use, even with intensive use. If necessary, all components are available as spare parts, ensuring a long operational life for the tool. Rothenberger, with over 70 years of experience in manufacturing tools for plumbers, ensures maximum construction quality and reliability over time.

Efficiency and savings

Using the ROLOCK EPT system allows for significant time savings compared to traditional joining techniques. There is no need to use consumables such as solder or gaskets, reducing operating costs. The ease of use also minimizes the risk of errors during installation, avoiding costly subsequent repairs. The quality of joints made with this system results in more efficient and durable systems, leading to long-term maintenance cost savings.
