## Summary description

Compression fitting by CALEFFI designed for multilayer plastic pipes with dimensions 16x2. Intended for continuous use in high-temperature systems, the fitting provides a mechanical connection for fluid-carrying pipelines. Suitable for heating and hot water installations where a durable, temperature-resistant joint for multilayer pipes is required.

## Long description

Compression fitting CALEFFI for multilayer plastic pipes continuous high-temperature use 16x2 is a mechanical connector designed to join multilayer plastic pipe sections with an outer diameter of 16 mm and a wall thickness of 2 mm. Manufactured by CALEFFI, the fitting is intended for pipeline systems that transport hot water or are subject to continuous elevated temperatures. The product provides a sealed, pressure-resistant joint without the need for solvent welding or soldering, making it suitable for modern heating and hot-water installations where reliable thermal performance is required.
Advantages
The compression fitting offers a compact design and simple assembly procedure that reduces installation time. Its construction materials are selected to withstand continuous high-temperature operation, ensuring long-term dimensional stability and leak resistance. The fitting enables a mechanical seal around the multilayer pipe and maintains pressure integrity under thermal cycling typical of heating systems.
Suitable for
Residential and commercial hot water supply lines
Central heating circuits and radiator connections
Underfloor heating systems using 16x2 multilayer pipes
Retrofit or replacement work where solderless connections are preferred
Key specifications
Compatible pipe size: 16 mm outer diameter, 2 mm wall thickness
Connection type: compression mechanical joint for multilayer plastic pipe
Intended use: continuous operation at elevated temperatures in hot-water and heating systems
Seal method: compression ring and nut creating a mechanical seal
Typical applications: potable hot water and heating circuits
How to use
Prepare the multilayer pipe by cutting it square and deburring the cut end. Slide the compression nut and compression ring onto the pipe, insert the pipe fully into the fitting body until it seats against the internal stop, and then tighten the compression nut to the recommended torque to form the seal. After assembly, verify alignment and pressure-test the circuit according to applicable installation standards to confirm there are no leaks. Follow standard safety and installation procedures for working on pressurized hot-water systems.
Usage recommendations
Use compatible 16x2 multilayer pipes and follow manufacturer torque values for the compression nut. Avoid excessive bending near the joint and perform a pressure and temperature test after installation to ensure long-term leak-free service.
