Straight Compression Coupling Comap GZ 18x2-1/2 TurboSKIN for piping connections

Straight compression coupling Comap GZ 18x2-1/2 TurboSKIN for piping connections is a mechanical screw-type connector engineered for joining pipes with an 18 mm outer diameter and a 2–1/2 mm wall. The coupling creates a threaded compression joint that is suitable for plumbing and heating systems, providing a secure, leak-resistant connection for repair, renovation and new-build installations. The TurboSKIN design improves handling during assembly and supports stable alignment of the connected pipe ends.

Advantages

The coupling delivers a reliable mechanical compression connection without the need for soldering or adhesive, reducing installation time and the need for special tools. Its construction ensures tight sealing under typical domestic and light-commercial water and heating pressures. The straight design allows for a compact inline connection and helps maintain uniform flow characteristics across the joint. Materials and geometry are selected to provide consistent performance and long service life when used within recommended operating conditions.

Suitable for

• Joining 18 mm outer diameter pipes with 2–1/2 mm wall thickness
• Domestic water supply installations
• Heating system pipe connections and repairs
• Renovation and replacement of existing inline sections
• New-build plumbing where mechanical compression joints are preferred

Key specifications

• Connection type: straight compression (screw) coupling
• Pipe outer diameter compatibility: 18 mm
• Pipe wall thickness compatibility: 2–1/2 mm
• Application: plumbing and heating piping systems
• Design feature: TurboSKIN for easier handling and alignment
• Installation orientation: inline straight joint

How to use

Prepare pipe ends by cutting squarely and removing burrs, then slide nut and compression components onto each pipe end as specified by the manufacturer's assembly sequence. Push pipe ends fully into the coupling body to achieve correct engagement, then tighten the compression nut to form the mechanical seal. Use appropriate wrenches and moderate torque consistent with pipe material and wall thickness to avoid deformation. After assembly, check the joint for leaks under working pressure and re-tighten slightly if required within recommended limits.

Usage recommendations

For optimal performance, use the coupling with pipes that match the stated 18 mm outer diameter and 2–1/2 mm wall thickness. Avoid excessive tightening that can damage pipe ends or fittings. Inspect joints periodically in systems exposed to vibration or thermal cycling, and follow local plumbing codes and manufacturer guidelines for pressure and temperature limits.
