T-piece 90° - reduced - N - 88,9-35-88,9mm IVAR.IVN41

Product detailed description

This 90° T-piece is part of press-fit stainless steel piping systems used in a variety of technical and industrial applications. Installers working in heating, ventilation, and sanitary systems will find this fitting essential for creating branch connections in press-fit pipe networks. It is commonly used in heating systems, fire suppression, and industrial piping where high chemical resistance and mechanical strength are required. The fitting supports both horizontal and vertical installations and integrates seamlessly with other press-fit components in stainless steel systems.

Its design allows for precise alignment and secure connection in tight spaces, making it ideal for complex piping layouts in commercial and industrial buildings. The fitting’s operating range accommodates both low-temperature environments and typical heating applications, ensuring versatility across multiple system types.

Technical parameters

Installation and connection

The T-piece is designed for use with press-fit stainless steel systems. The connection requires a compatible press tool to compress the fitting onto the pipe ends. The internal sealing mechanism includes an EPDM O-ring that ensures leak-free operation when properly seated. The fitting has three press-fit connection points with diameters of 88.9 mm, 35 mm, and 88.9 mm respectively. Before pressing, the installer must verify the pipe ends are clean, free of burrs, and within the specified dimensional tolerances.

A common mistake during installation is failing to align the fitting correctly before pressing, which can lead to uneven compression and potential leaks. Another frequent error is over-pressing, which can damage the O-ring or deform the fitting. It is crucial to follow the manufacturer’s pressing depth indicators to ensure proper engagement of the ferrule and O-ring. After installation, the system should be tested for tightness using air or water pressure to confirm the integrity of the joint.

Compatibility and accessories

This T-piece is compatible with other press-fit stainless steel fittings from IVAR, including elbows, couplings, and straight connectors. To ensure system integrity, all components must be from the same press-fit system to maintain uniformity in pressing tools and sealing methods. When ordering, installers should also consider additional components such as press tools, cutting tools, and deburring devices to facilitate accurate and efficient installation.

Technical background for designers

The 90° T-piece operates by forming a rigid, leak-tight connection through mechanical compression of the pipe into the fitting body. The EPDM O-ring ensures a tight seal even under fluctuating pressure and temperature conditions. Designers should consider the system’s hydraulic requirements, including flow rate and pressure drop, when integrating this fitting into the overall layout. The fitting’s geometry allows for smooth media flow while minimising turbulence and pressure loss in the branch line.

The long-term performance of the fitting depends on the quality of the installation, correct tooling, and adherence to the manufacturer’s specifications. Proper alignment and pressing depth are essential to prevent premature failure due to stress concentrations or misalignment. The fitting is suitable for systems requiring high reliability and minimal maintenance over time.

Service and operation

During operation, the T-piece requires no active maintenance if installed correctly. However, periodic inspections are recommended to detect signs of wear, misalignment, or potential leaks. Any visible deformation or loosening of the press joint should be investigated immediately. The system should be depressurised and isolated before any inspection or repair work is carried out. No scheduled service intervals are specified for this component based on the manufacturer’s technical documentation.

Frequently asked questions
