Press fitting stopper - N - 35mm IVAR.IVN51

Product detailed description

Press stoppers are essential components in press pipe systems, used to seal ends of pipes during installation or maintenance. This model is commonly used in residential and commercial buildings for heating, sanitary, and industrial systems. Installers working with stainless steel press systems will find this stopper suitable for applications requiring a durable and corrosion-resistant seal. The device is designed for use in closed systems where a secure and leak-free connection is required. It is frequently used in systems where the pipe is cut and needs to be sealed temporarily or permanently.

Technical parameters

Material	Stainless steel grade 1.4404 (AISI 316L)
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN51.35
Brand	IVAR

The operating temperature range of -20°C to +120°C makes this stopper suitable for both cold and hot water systems, as well as heating circuits. The nominal pressure rating of PN 16 indicates its ability to handle medium-pressure applications. The material, stainless steel grade 1.4404 (AISI 316L), ensures resistance to corrosion and is suitable for use with water, steam, and inert gases. These parameters are critical for correct system sizing and compatibility with other press components.

Installation and connection

The IVN51.35 press stopper is installed using a standard press tool compatible with 35mm stainless steel press systems. The connection size is 35mm, and the fitting must be pressed to a depth of 54mm with an indicator to ensure proper seating. Before pressing, the pipe end must be clean and free of burrs. A common mistake during installation is not pressing to the correct depth, which can lead to leaks or failure. It is important to verify the press tool is correctly calibrated for the material and diameter. After pressing, the seal should be visually inspected for any signs of misalignment or damage.

Compatibility and accessories

This stopper is compatible with IVAR stainless steel press systems and is intended for use with pipes of the same diameter and material. It is typically used in conjunction with other press fittings such as elbows, tees, and couplings. No additional accessories are required for installation, but a suitable press tool must be available. It is important to ensure that all components in the system are from the same manufacturer and system type to avoid compatibility issues.

Technical background for designers

The press stopper functions by creating a mechanical and hydraulic seal between the pipe and the fitting. The stainless steel material offers high strength and resistance to corrosion, making it suitable for long-term use in a variety of environments. The press connection ensures a leak-free joint by compressing the fitting around the pipe. The system's efficiency and service life depend on correct installation, including proper pressing depth and alignment. The material's properties also allow it to maintain integrity under thermal expansion and contraction, which is common in heating and hot water systems.

Service and operation

Once installed, the press stopper requires minimal maintenance. There are no service intervals specified for this model, as it is designed for long-term use. However, it is recommended to inspect the connection visually during routine system checks for signs of wear, corrosion, or leakage. If a leak is detected, the fitting should be replaced immediately. The stopper should not be reused if the press mark is damaged or if the indicator is not properly engaged.
