Brass Coupling Sleeve Series 7000 PN16 | PE Tube Junction

The 7000 series straight brass coupling sleeve is the essential junction fitting for connecting two polyethylene pipes (HDPE or LDPE) of the same diameter. Designed to ensure a perfectly axial and secure bond under pressure, this mechanical compression fitting offers a robustness far superior to plastic solutions. Certified to withstand a nominal pressure of 16 bar (PN16), it is the reference solution for extending or repairing your water supply networks with unfailing reliability.

A brass structure for maximum durability

The solid brass construction of the 7000 series guarantees exceptional resistance to mechanical stresses, such as traction, torsion or ground movement. Unlike polymeric materials, brass is insensitive to UV rays and provides natural protection against permeation, which is crucial for maintaining drinking water quality. Its exceptional longevity makes it a long-term investment for all hydraulic infrastructures buried or exposed to the elements.

Compression Outer Clamping Technology

This coupling sleeve uses a mechanical clamping system that does not require any complex specific tooling or welding. The seal is ensured by a high-performance O-ring, while a metal cramping ring bites the PE tube when screwing in the nuts. This device prevents the tube from being dislodged or torn off, even in the event of strong pressure fluctuations or water hammer in the circuit. The assembly is fast, clean and immediately operational.

A smooth and secure connection

Thanks to its integral passage, this connection limits pressure losses and ensures optimal hydraulic flow between the two pipe sections. Its symmetrical design allows for simplified installation, ideal for emergency repairs on severed pipes or for the extension of existing networks. The precision of the machining of the threads of the brass nuts facilitates tightening, ensuring uniform compression of the joint over the entire circumference of the polyethylene tube.

Technical characteristics

Installation and maintenance tips

For a successful assembly, make sure that both ends of the PE pipes are cut squarely and free of any burrs. Insert each tube to the center stop of the sleeve. Tightening must be done firmly to engage the cramping ring. This brass fitting does not require any special maintenance after installation; Its natural corrosion resistance makes it a trusted choice for drinking water networks, sprinkler and pumping facilities.
