Nipple - reduced, 1/2" M x EK, 500676

Product detailed description

Reduced nipples are commonly used in central heating systems, plumbing and sanitation networks to connect flexible pipe systems to rigid threaded fittings. They ensure leak-free connections between different pipe types and diameters. Installers working with IVAR TR, TP and TA flexible copper-aluminium composite pipes frequently use these components to adapt pipe ends to internal thread connections in valves, radiators or manifolds. Proper selection and installation are essential for long-term performance and system integrity.

The nickel-plated brass construction provides corrosion resistance and durability in wet and heated environments. The EPDM sealing ring ensures a tight fit and prevents leakage. This component is suitable for use in domestic and commercial buildings, including residential heating systems, underfloor heating circuits and hot water distribution lines.

Technical parameters

Installation and connection

Before installation, confirm that the internal thread on the receiving component matches the external thread of the nipple. Use a suitable wrench to tighten the connection without over-torquing, which could damage the sealing ring or threads. Ensure the EPDM O-ring is properly seated in the groove and not twisted during assembly. Common installation errors include incorrect thread alignment, insufficient tightening or using incompatible sealing materials. Always verify the connection for leaks after installation and before commissioning the system.

Compatibility and accessories

This reduced nipple is specifically designed for IVAR TR, TP and TA flexible pipe systems. It requires compatible pipe ends and internal-threaded components such as valves, manifolds or adapters. When ordering, ensure that the complete set includes all necessary sealing rings and that the pipe is cut cleanly and deburred prior to installation. No additional products are required for basic installation.

Technical background for designers

The operating principle involves creating a mechanical and sealed connection between a flexible pipe end and a rigid threaded fitting. The nickel-plated brass CW617N material provides good thermal conductivity and resistance to corrosion in water-based systems. The EPDM sealing ring ensures a watertight seal under operating conditions. Integration into the system depends on correct sizing and alignment. Long-term performance is affected by installation quality, operating pressure and temperature fluctuations. Avoid using with aggressive media or in environments exceeding the specified temperature limit.

Service and operation

During regular system checks, inspect the connection for signs of leakage, corrosion or mechanical stress. Re-tighten if necessary, but avoid excessive force. Replace the EPDM sealing ring if damaged or degraded. No scheduled service intervals are defined for this component. Any defects should be addressed immediately to prevent system failure.

Frequently asked questions

Can this nipple be used with IVAR TA pipes?
Yes, the design is compatible with IVAR TR, TP and TA pipe types.

What is the maximum operating temperature for this fitting?
The maximum operating temperature is +120 °C according to the manufacturer's specifications.

Is an EPDM sealing ring included in the packaging?
The sealing ring is not included separately; it is part of the standard manufacturing process and pre-installed in the fitting.

Can this fitting be used in high-pressure systems?
It is rated for PN 10 and therefore suitable for low to medium-pressure applications only.
