Rothenberger - ROLOCK EPT Set, 1/2-5/8-7/8-1.1/8' - 12524

Features of the Rothenberger ROLOCK EPT Set

The Rothenberger ROLOCK EPT Set (item code 12524) is a professional solution for processing thin-walled copper, aluminum, and stainless steel pipes. This kit includes an expander plier with interchangeable heads in sizes 1/2, 5/8, 7/8, and 1-1/8 inches, designed to create precise and reliable connections in refrigeration and air conditioning systems.

Main Applications

This set is optimally used in various professional contexts:

• Installation and maintenance of commercial and industrial refrigeration systems
• Residential and commercial air conditioning systems
• Plumbing systems requiring solderless connections
• Repairs on existing piping where it is necessary to expand the pipe to insert fittings
• Precision work on copper piping for HVAC applications

Technical Advantages

The ROLOCK EPT Set stands out for numerous technical aspects that make it a reliable tool for professionals:

• Precise expanding system ensuring perfectly sealed joints
• Ratchet mechanism reducing the effort required during operation
• Hardened interchangeable heads for increased durability
• Ergonomic plier design allowing prolonged use without fatigue
• Compatibility with pipes of different thicknesses thanks to optimized calibration
• Uniform expansion preventing deformation and ensuring hydraulic seal

Technical Specifications

The set includes high-quality components designed to withstand intensive use on site:

• Expander plier with forged and heat-treated steel body
• 4 expander heads in sizes: 1/2 (12.7 mm), 5/8 (15.9 mm), 7/8 (22.2 mm), and 1-1/8 (28.6 mm)
• Compatibility with copper pipes with thicknesses from 0.8 to 1.5 mm
• Manual operation without the need for electrical power
• Impact-resistant plastic case for transport and storage
• Overall kit weight: approximately 1.8 kg

Operation and Use

Using the ROLOCK EPT Set is intuitive even for less experienced technicians. After selecting the appropriate size expander head and mounting it on the plier, simply insert it into the pipe and operate the ratchet mechanism. Expansion occurs gradually and controlled, allowing for a uniform widening of the pipe end. This enables the insertion of fittings or another pipe, creating a secure joint that, once cooled, contracts slightly, ensuring an optimal seal.

Maintenance and Durability

To maintain the efficiency of the ROLOCK EPT Set over time, it is advisable to regularly clean the expander heads of material residues and occasionally lubricate the plier mechanism. The parts are made with high-quality materials that ensure wear resistance even under intensive working conditions. The included case effectively protects the tools during transport and storage, preventing accidental damage and keeping all components of the set organized.
