This comprehensive kit includes expander heads in sizes 3/8, 1/2, 5/8, 3/4, 7/8, 1, and 1-1/8 inches, allowing it to handle a wide range of applications in plumbing, refrigeration, and air conditioning.

Technical Specifications

The ROLOCK EPT set (item code 12536) is constructed with high-quality materials to ensure durability and consistent performance. The expander heads are made of specially heat-treated steel to resist wear even after repeated use. The expansion mechanism is designed to ensure uniform tube flaring, creating perfectly sealed joints without deformation.

Practical Applications

This set is used in numerous professional contexts:

• Installation and maintenance of commercial and industrial refrigeration systems
• Construction of air conditioning systems
• Plumbing installations in residential and commercial buildings
• Repair of copper and aluminum tubing
• Creation of connections for solar thermal systems

Advantages of the ROLOCK EPT System

Rothenberger expansion technology offers numerous benefits compared to traditional joining methods:

• Elimination of the need for additional fittings, resulting in material savings
• Reduction of potential leak points in the system
• Creation of stronger and more durable joints over time
• Greater hydraulic efficiency due to the absence of flow restrictions
• Faster installation process compared to welding or brazing

Ergonomics and Ease of Use

The ergonomic design of the tool allows for comfortable use even in confined spaces. The expansion mechanism requires minimal physical effort thanks to the optimized lever system. The interchangeable heads can be quickly mounted and dismounted, allowing for switching between sizes in seconds. The carrying case included in the set ensures perfect organization of tools and easy transport to the job site.

Maintenance and Durability

The ROLOCK EPT set is designed for long-lasting use with minimal maintenance.
