T-piece press, 40 x 40 x 40

Product detailed description

Press T-pieces are commonly used in domestic and commercial heating and plumbing systems to create branch connections in closed-loop circuits. They are essential in installations involving radiant floor heating, underfloor manifolds, and zone control systems. In such applications, the fittings ensure accurate flow distribution and system integrity under thermal stress. Installers working with ALPEX cross-linked polyethylene pipes rely on press fittings to maintain tight, leak-free joints without the need for soldering or threading.

Proper selection and installation of press T-pieces are critical for system performance. The fitting must match the pipe size and system pressure requirements. The nickel-plated brass construction offers resistance to corrosion and ensures long-term reliability in wet environments. The EPDM sealing ring provides a durable and flexible seal compatible with ALPEX pipe surfaces. When installed correctly, these fittings contribute to the longevity and efficiency of the entire piping network.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.674 kg
Code	512035
Brand	IVAR

The nominal pressure rating PN 10 indicates that the fitting is suitable for systems operating at a maximum of 10 bar. The operating temperature limit of +120°C makes it appropriate for hot water and heating applications. These parameters are important for ensuring compatibility with the system design and for selecting the correct fitting for the intended service conditions.

Installation and connection

To install the press T-piece, first ensure the ALPEX pipe ends are clean and free of debris. Insert the pipe into the fitting until it reaches the stop mark. Use a calibrated press tool to apply even pressure around the circumference of the fitting. The press tool must be compatible with the fitting type and must be set to the correct pressing force according to the manufacturer’s specifications. Verify that the press marks are evenly distributed and that the tool does not slip during the pressing process. After pressing, inspect the joint visually and with a go/no-go gauge to confirm proper engagement. Common installation errors include insufficient pressing force, misalignment of the pipe and fitting, and using a tool not calibrated for the specific fitting type. These can lead to leaks or premature failure.

Compatibility and accessories

This press T-piece is specifically designed for ALPEX cross-linked polyethylene pipes of equal diameter. It requires a compatible press tool and a calibration certificate to ensure correct pressing. No additional accessories are required when used with standard ALPEX pipe systems. The EPDM sealing ring is factory-fitted and does not require replacement unless damaged during installation.

Technical background for designers

The press T-piece operates on the principle of mechanical deformation. When pressed, the metal sleeve compresses the pipe wall and forms a secure, watertight joint. The nickel-plated brass body (CW617N) provides high strength and resistance to thermal expansion. The stainless steel clamp ensures uniform pressure distribution around the pipe, while the EPDM seal compensates for minor surface irregularities and maintains a tight connection over time. The fitting integrates seamlessly into systems with ALPEX pipe and is suitable for both new and retrofit installations. System efficiency is influenced by correct sizing, proper alignment, and adherence to pressing specifications. Long-term performance depends on the quality of the press operation and the absence of mechanical stress on the joint.

Service and operation

During operation, the fitting requires no active maintenance. However, it should be inspected periodically for signs of wear, deformation, or leakage. Any visible damage to the fitting or surrounding pipe should be investigated immediately. The fitting is not designed for disassembly after installation; any faulty joint must be cut out and replaced with a new fitting and pipe section.

Frequently asked questions

Can this press T-piece be used with copper or steel pipes?
No, it is designed specifically for ALPEX cross-linked polyethylene pipes. Using it with other materials may compromise the seal and structural integrity.

Is a special press tool required for installation?
Yes, the fitting must be pressed using a tool compatible with the fitting type and calibrated according to the manufacturer’s guidelines.

Can the EPDM sealing ring be replaced after installation?
No, the sealing ring is factory-fitted and cannot be accessed or replaced once the fitting is pressed onto the pipe.

How is the correct pressing force determined?
The required pressing force is specified in the manufacturer’s technical documentation and depends on the fitting size and material. It must be applied evenly around the fitting using a calibrated press tool.
