## Long description

SiGMA-Li EK-16 eurocone compression fitting is designed to create a sealed mechanical connection between 3/4" x 16 x 2 PEX piping and standard eurocone valves or fixtures. Intended for domestic and commercial water supply installations, this fitting provides a compact, straightforward solution for connecting PEX distribution lines to mixers, shut-off valves and other plumbing fixtures that accept eurocone-style connections.
Advantages
The compression eurocone design ensures a secure, leak-resistant joint without the need for soldering or specialized tools. Manufactured to fit 3/4" x 16 x 2 PEX pipes, the fitting offers consistent dimensional accuracy for repeatable installations. Its mechanical sealing principle allows easy disassembly and reassembly for maintenance or replacements, while compatibility with standard eurocone valve geometry simplifies integration into existing plumbing systems.
Suitable for
Connecting PEX distribution pipes to eurocone bathroom and kitchen fixtures
Domestic and light commercial potable water supply installations
Replacement or retrofit connections where eurocone-compatible valves are used
Situations requiring a mechanical, solder-free joint for PEX piping
Key specifications
Connection type: compression eurocone for eurocone-compatible valves and fittings
Pipe compatibility: PEX pipe with nominal dimensions 3/4" x 16 x 2
Material: corrosion-resistant components suitable for potable water systems
Sealing method: mechanical compression seal designed for repeatable assembly
Application: potable water distribution in domestic and commercial environments
How to use
Prepare the PEX pipe end by cutting it square and deburring to ensure a clean contact surface. Slide the compression sleeve and nut onto the pipe, insert the eurocone fitting fully into the valve or fixture connection, then tighten the compression nut by hand and finish with a wrench to the manufacturer-recommended torque. After installation, check the joint for leaks and perform a pressure test in accordance with local plumbing standards. Follow the fixture and valve manufacturer instructions for specific tightening and assembly details.
Usage recommendations
Use appropriate tools to cut and prepare PEX pipe ends for a reliable seal; avoid excessive tightening of the compression nut to prevent deformation of the pipe or fitting. Verify compatibility with the receiving eurocone valve dimensions before installation and comply with local plumbing codes for potable water systems.
