Compression straight coupling Comap GZ 26x3-1 TurboSKIN, threaded compression pipe fitting

Compression straight coupling Comap GZ 26x3-1 TurboSKIN is a threaded compression pipe fitting designed to join pipes with a 26x3 mm cross-section. Intended for plumbing and heating systems, this coupling creates a sealed mechanical connection between compatible metal or composite pipes. The fitting is suitable for repair, installation or extension tasks where a press-resistant, leak-tight joint is required and where a threaded compression solution is preferred over soldering or fusion methods.

Advantages

The coupling offers a compact, low-profile design that enables installation in confined spaces without specialized tools. Its threaded compression mechanism provides a repeatable, reliable seal and allows for disassembly and reassembly if maintenance or replacement is needed. The TurboSKIN feature enhances the contact surface for improved grip and seal integrity, reducing the risk of leaks under standard operating pressures for domestic and light commercial plumbing and heating systems.

Suitable for

• Joining 26x3 mm metal or composite pipes in plumbing systems
• Connecting pipes in heating installations such as radiators and boiler circuits
• Repairing or extending existing pipe runs where a threaded compression joint is required

Key specifications

• Connection type: threaded compression straight coupling
• Compatible pipe dimension: 26 x 3 mm
• Material: corrosion-resistant metallic components suitable for plumbing
• Seal type: mechanical compression sealing (TurboSKIN-enhanced contact surface)
• Application: cold and hot water, central heating circuits in domestic and light commercial use

How to use

Ensure pipe ends are cut square, deburred and clean before assembly. Slide the compression nut and ferrule components onto the pipe, insert the pipe fully into the coupling body until it seats, then tighten the compression nut by hand and finish to the specified torque with appropriate wrenches to compress the ferrule and form the seal. Do not overtighten; follow manufacturer torque guidance where available. After assembly, pressure-test the system according to local standards to confirm leak-free joints.

Usage recommendations

Use with pipes matching the stated 26x3 mm dimension and compatible materials; avoid using the coupling with undersized, oversized or heavily corroded pipe ends. For systems carrying aggressive chemicals or gases, verify material compatibility before installation. When installing in concealed locations, ensure joints are pressure-tested prior to concealment and consider access for future maintenance.
