Brass Sleeve Series 7000 PE Steel Dimensions | PN 25 bar

The 7000 Series Compression Coupling Sleeve is a high-end junction piece specifically developed for the connection of polyethylene (PE) pipes with external dimensions equivalent to steel pipes. Made of CW617N brass, this straight fitting allows two sections of tubes to be connected with exceptional mechanical strength. Whether for drinking water supply, agricultural irrigation or technical irrigation networks, this sleeve guarantees structural continuity and absolute waterproofing over the long term.

Robust engineering for high pressure

This coupling sleeve is distinguished by its outstanding hydraulic performance. Its solid brass structure is designed to withstand extreme stresses, with a PN 25 bar certified resistance for diameters ranging from 16 mm to 50 mm. For larger networks (diameter greater than 50 mm), it maintains a PN 16 bar reliability. This ability to withstand pressure peaks and water hammer makes it the preferred fitting for professional installations requiring the highest level of safety.

Ergonomics and assembly precision

The fitting assembly has been designed to facilitate the work of installers in the field. The clamping nut, recognizable by its chrome finish, is extra-wide to offer a better grip and smooth screwing. In addition, the body of the fitting incorporates holding plates specifically sized for standard wrenches on the market. This design allows the fitting to be perfectly immobilized during the final phase of compression, thus ensuring a uniform bite of the ring on the tube without the risk of twisting the pipe.

Sealing and high-quality components

The compression technology of this sleeve is based on an H62 brass notched ring that ensures an unboltable mechanical anchorage to the PE tube. Hydraulic sealing is entrusted to a precision O-ring made of NBR or EPDM, capable of maintaining its elastic properties between 0°C and +50°C. Compliant with DIN 8076, this system ensures a leak-free connection, even in environments subject to vibration or significant hydraulic load variations.

Technical characteristics

Sanitary compliance and areas of application

Fully compliant with French legislation relating to materials in contact with water intended for human consumption, this sleeve is a safe solution for drinking water networks. Its universality allows it to be used in the industrial sector as well as in landscaping or agriculture. Its ability to adapt to PE pipes with "steel" dimensions makes it a valuable transition fitting for the renovation of old networks or the extension of mixed networks requiring industrial reliability.
