Stopper press fittings 28

Product detailed description

Press stopper fittings are essential components in closed pressurised systems, particularly in central heating, fire suppression and industrial air or gas systems. Installers working in residential, commercial and industrial buildings often use these fittings to seal pipe ends during installation or maintenance. The IVAR IVC51.28 model is specifically designed for use in systems operating with water, dry air, inert gases and industrial media. The fitting is constructed from carbon galvanized steel and is compatible with Type M jaws for press fitting tools. The absence of surface coating limiting agents ensures reliable sealing when properly molded.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.05 kg
Code	IVC51.28
Brand	IVAR

The operating temperature range of -20 °C to +120 °C allows for use in both cold and moderately heated environments. The PN 16 rating indicates a nominal pressure of 16 bar, which is suitable for most heating and industrial systems. These parameters are critical for ensuring the fitting is correctly sized and selected for the intended application, particularly in systems with fluctuating temperatures and pressures.

Installation and connection

The IVAR IVC51.28 is installed using a press fitting tool compatible with Type M jaws. The 28 mm diameter fitting is designed for seamless integration into existing pipe systems. During installation, it is essential to ensure the pipe end is clean and free from burrs. The press fitting should be aligned with the pipe and pressed until the molding indicator is engaged. Common installation mistakes include improper alignment, insufficient pressing force and using incompatible jaws. After installation, the joint should be inspected for any visible gaps or misalignment.

Compatibility and accessories

The IVAR IVC51.28 is compatible with other IVAR press fittings and systems that use Type M jaws. For complete installation, ensure that the necessary press tools and jaws are available. No additional surface coatings or sealing agents are required for this fitting. The fitting is not certified for use with drinking water, so alternative materials should be selected for potable water systems.

Technical background for designers

The IVAR IVC51.28 operates on the principle of mechanical compression, where the press tool deforms the fitting around the pipe to create a secure and leak-proof joint. The carbon galvanized steel material provides good resistance to corrosion and mechanical damage. The fitting is designed for integration into closed pressurised systems, including central heating, fire suppression and industrial air or gas systems. The service life and efficiency of the fitting are influenced by the quality of the installation, the condition of the pipe and the operating conditions of the system.

Service and operation

No specific service intervals are provided for the IVAR IVC51.28. However, during routine system checks, installers should inspect the fitting for signs of wear, corrosion or leakage. The molding indicator should be checked to ensure the fitting has been properly pressed. Any damaged or suspect fittings should be replaced immediately to maintain system integrity.
