Stopper 35

Product detailed description

Press-fit stoppers are essential components in closed pressurised systems such as central heating, fire protection, and refrigeration installations. They are commonly used in residential, commercial, and industrial buildings to seal pipe ends during installation or maintenance. Installers working with press-fitted systems benefit from the quick and secure assembly of these components, eliminating the need for welding or threaded joints. The IVAR IVC50.35 is specifically designed for use in systems operating under high pressure and a wide temperature range, making it suitable for applications involving dry air, inert gases, and water-based systems.

Technical parameters

Material	Carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.079 kg
Code	IVC50.35
Brand	IVAR

The operating pressure rating of PN 16 indicates that the stopper can safely handle pressures up to 16 bar, which is critical for systems with high hydraulic demands. The material and sealing properties ensure compatibility with a range of media, including water and inert gases. The specified temperature range allows for use in environments with fluctuating thermal conditions, from cold storage facilities to heated industrial systems.

Installation and connection

The IVAR IVC50.35 is installed using Type M jaws, which compress the fitting onto the pipe. The press-fit indicator ensures correct installation up to 54 mm. The stopper must be fully seated and aligned with the pipe to prevent leaks. Common installation errors include using incorrect jaw types or failing to verify the press-fit indicator. After installation, the system should be tested for pressure integrity. The stopper is not suitable for drinking water systems and must be used in accordance with the manufacturer’s guidelines for media compatibility.

Compatibility and accessories

This stopper is compatible with IVAR press-fit systems and other systems using Type M jaws. It is intended for use with carbon steel pipes of the specified diameter. No additional surface coatings or limiting agents are required, but the system must be press-fitted correctly. No specific accessories are required for installation, but the use of the correct jaw type is essential for a secure fit.

Technical background for designers

The IVAR IVC50.35 operates on the principle of mechanical compression, where the fitting is pressed onto the pipe to form a tight seal. The carbon galvanized steel construction provides resistance to corrosion and mechanical damage, while the EPDM O-ring ensures a watertight seal. The material properties allow for integration into a variety of pressurised systems, including those with fluctuating temperatures. The service life and efficiency of the stopper depend on correct installation, the quality of the press-fit, and the compatibility of the system media with the materials used.

Service and operation

The stopper requires no regular maintenance if installed correctly. However, periodic pressure tests are recommended to ensure system integrity. If a leak is detected, the stopper should be inspected for damage or improper seating. The system should be depressurised before any inspection or replacement. No specific service intervals are provided, but adherence to standard system maintenance practices is advised.

Frequently asked questions
