Nipple press - PPSU, 50 x 50

Product detailed description

Press nipples are essential components in systems where ALPEX pipes are used for hot and cold water distribution, heating circuits, and sanitation. They are commonly found in residential and commercial buildings, including multi-family homes, industrial facilities, and public infrastructure. Installers working with press systems must ensure correct sizing, alignment, and sealing to maintain system integrity and prevent leaks. This model is intended for use in systems with equal-diameter pipe connections and is compatible with standard press tools and procedures.

Correct selection and installation of press nipples are crucial for the long-term performance of the system. The material properties, pressure and temperature ratings, and compatibility with the pipe and tooling must be verified before installation. This model is designed for use in environments where the medium temperature does not exceed +120°C and the system pressure is within PN 10 limits. It is suitable for both new installations and repairs in press-fitting systems.

Technical parameters

Material	Plastic PPSU
Operating temperature	+120 °C
Nominal pressure	PN 10
EAN	4013960368536
Weight	0.18 kg
Code	88450100
Brand	IVAR

The nominal pressure of PN 10 indicates that the fitting is suitable for systems operating at up to 10 bar. The maximum operating temperature of +120°C means it is suitable for hot water and heating applications. These parameters are essential for determining the fitting's suitability for specific system conditions and for ensuring correct sizing and selection in design and installation phases.

Installation and connection

The press nipple is installed by inserting it into the prepared ends of two ALPEX pipes of the same diameter. The stainless steel sleeve is positioned over the pipe and fitting, and the EPDM sealing ring is seated in the groove. A press tool is then used to compress the sleeve around the pipe and fitting, creating a secure, leak-tight connection. The connection size is 50 x 50, meaning it is suitable for 50 mm diameter pipes. During installation, it is important to ensure that the pipe ends are clean, straight, and free from burrs. A common mistake is incorrect positioning of the sleeve or failure to fully compress the joint, which can lead to leaks or reduced system performance.

Compatibility and accessories

This press nipple is specifically designed for use with ALPEX pipes of the same diameter. It requires a compatible stainless steel sleeve and EPDM sealing ring, which are typically included in the fitting package. For installation, a suitable press tool must be used to ensure proper compression of the sleeve. No alternative or related products are specified for this model.

Technical background for designers

The operating principle of the press fitting is based on mechanical compression of the sleeve around the pipe and fitting, creating a tight seal. The PPSU material is chosen for its high resistance to thermal and chemical stress, making it suitable for hot water and heating systems. The stainless steel sleeve provides mechanical strength and durability, while the EPDM sealing ring ensures a tight, leak-free connection. The integration into the system depends on correct alignment, pressure and temperature conditions, and the use of appropriate tools. The service life and efficiency of the fitting are influenced by the quality of the installation, the condition of the pipe ends, and the compatibility of the materials used.

Service and operation

No specific service intervals are provided for this model. During operation, it is important to inspect the connection for signs of leakage, especially after installation or following system pressure changes. The integrity of the press joint should be visually checked for deformation or misalignment. If any issues are detected, the fitting should be replaced or re-pressed using the correct procedure.

Frequently asked questions
