Nipple PUSH-PPSU - 26x26 IVAR.PUSH-V

Product detailed description

Push-fit couplings are commonly used in residential and commercial heating and plumbing systems to connect flexible plastic piping without the need for compression tools. This fitting allows for quick and secure installation in systems where space is limited or frequent disassembly is required. Installers typically work with these fittings in underfloor heating, domestic hot water, and central heating applications. They are suitable for systems operating at moderate pressures and temperatures, ensuring reliable performance in environments such as bathrooms, kitchens, and mechanical rooms.

When installing, the fitting is pushed onto the prepared pipe ends until it clicks into place. The internal sealing ring ensures a watertight connection, while the metal ferrule grips the pipe wall. These components work together to maintain the integrity of the joint over time, even when exposed to thermal expansion and contraction. The fitting must be used with compatible pipe diameters and must not be over-tightened or misaligned during assembly.

Technical parameters

The nominal pressure rating of PN 10 means the fitting is suitable for systems operating at up to 10 bar. The maximum operating temperature of +120°C is appropriate for hot water and heating applications. When selecting this component, ensure the system conditions match these ratings to avoid premature failure. The PPSU material offers good chemical resistance and mechanical strength, making it suitable for long-term use in closed-loop systems.Installation and connection To install the coupling, first clean and dry the pipe ends. Ensure there is no debris or burrs that could interfere with the seal. Insert one end of the pipe into the push-fit side of the coupling until it reaches the stop mark. The second end is threaded into a corresponding male thread. Always verify that the ferrule is seated correctly and that the EPDM sealing ring is undamaged. Common mistakes include using mismatched pipe diameters, applying excessive force during insertion, or failing to check for proper seating after installation. Always test the system for leaks after completion.Compatibility and accessories This coupling is specifically designed for ALPEX pipes of the same diameter. It should not be used with rigid copper or steel piping. When assembling a system, ensure that all related fittings, such as elbows, tees, and valves, are also compatible with the push-fit system. Additional components such as unions or adapters may be required if connecting to threaded or flanged systems. No specific accessories are required for standard installation with this model.Technical background for designers This coupling operates on the push-fit principle, where the EPDM sealing ring forms a watertight barrier between the pipe and the fitting. The PPSU housing provides structural support and resistance to thermal stress. The stainless steel ferrule compresses around the pipe when installed, preventing axial movement and ensuring long-term reliability. The design integrates seamlessly into closed-loop heating and hot water systems. System longevity depends on correct installation, adherence to pressure and temperature limits, and the use of compatible materials throughout the circuit.Service and operation Routine inspection is not required for this fitting unless system failures occur. Check for signs of leakage, discolouration, or deformation during periodic maintenance. If a joint fails, it can be replaced without cutting the pipe by using a push-fit disconnect tool. There are no scheduled service intervals specified for this model. In the event of system shutdowns or long-term non-use, ensure that the system is drained and protected against freezing if applicable.Frequently asked questions

Can this coupling be used with other types of plastic pipe?
No. It is specifically designed for ALPEX pipes and will not form a secure connection with other types of flexible or rigid piping.

Is it possible to reuse the coupling after removal?
No. Once removed, the ferrule and sealing ring may be damaged and should not be reused. A new fitting must be installed for a reliable connection.

How does the ferrule prevent leaks?
The ferrule is made of stainless steel and compresses around the pipe wall during installation, creating a mechanical lock that prevents axial movement and maintains a tight seal.

What is the effect of high temperatures on the PPSU housing?
PPSU is stable at up to +120°C and retains its structural integrity and sealing properties within this temperature range, making it suitable for hot water and heating systems.
