T-piece 90° - reduced - N - 108-54-108mm IVAR.IVN41

Product detailed description

Reduced T-pieces are essential components in press-fitting systems where directional changes and flow distribution are required. They are commonly used in residential and commercial buildings for heating, sanitary and industrial piping systems. Installers working on these systems often deal with tight spaces and complex routing, where accurate fitting and secure connections are critical. This 90° reduced T-piece ensures reliable performance in environments with fluctuating temperatures and varying pressure conditions.

The model IVN41.10854108 is designed for applications requiring a reduction in one of the branch lines while maintaining the integrity of the main flow path. Its compact design and press-fit connection make it ideal for systems where space is limited and high precision is necessary. This component supports a wide range of installations, including those involving water, steam, inert gases and low-pressure air.

Technical parameters

Installation and connection

Installation requires a press tool capable of forming a secure connection without damaging the component. The T-piece features three press connections: two at 108 mm and one at 54 mm. Before pressing, ensure that the pipe ends are clean and free from burrs. The O-ring must be seated correctly in its groove to prevent leakage. The alignment of the branches should be checked visually and with a square to maintain proper 90° geometry. A common mistake during installation is incorrect pressing depth, which can lead to incomplete engagement and potential leaks. Always verify the presence of the colour indicator changing to confirm a successful connection.

Compatibility and accessories

This T-piece is compatible with other stainless steel press fittings and pipes of the same material and standard. It is intended for use with EPDM sealing rings and press tools designed for stainless steel systems. Additional components such as straight or angled press fittings may be needed depending on the specific layout of the system. For more complex configurations, consider using expansion joints or unions to allow for thermal movement.

Technical background for designers

The T-piece operates by allowing fluid to pass through the main line while branching off at a right angle with a reduced diameter. The EPDM O-ring provides a flexible seal that compensates for minor misalignments and thermal expansion. When integrated into a system, the T-piece contributes to the overall hydraulic balance and pressure distribution. The service life of the component is influenced by the quality of the installation, the cleanliness of the system and the stability of the operating conditions.

Service and operation

Regular visual inspections are recommended to identify signs of wear, corrosion or leakage. If a leak is suspected, the system should be depressurised and the connection inspected for damage or misalignment. No specific service intervals are provided for this component, but any issues should be addressed promptly to avoid further damage to the system. The sealing ring should be replaced if it shows signs of degradation or if the connection is reworked.

Frequently asked questions

Can the T-piece be used in solar heating systems?
Yes, it is suitable for solar systems due to its resistance to temperature fluctuations and compatibility with hot water.

Is the T-piece compatible with stainless steel pipes of different wall thicknesses?
It is designed for use with standard stainless steel pipes; wall thickness variations should be within the manufacturer’s specifications.

What happens if the sealing ring is not seated correctly?
An improperly seated O-ring can cause leakage and reduce the effectiveness of the connection. Always check the seating before pressing.

Can this T-piece be used in industrial gas applications?
Yes, it is suitable for inert gases as long as the operating conditions remain within the specified temperature and pressure limits.
