Connection fitting - internally threaded - N - 54mm-Rp2" IVAR.IVN62

Product detailed description

Internally threaded connection fittings are essential components in press and threaded systems used in residential, commercial and industrial buildings. They enable secure and leak-free connections between pipes and fittings in heating, plumbing, fire suppression and industrial systems. These fittings are commonly used in central heating circuits, domestic hot water systems and compressed air lines where reliable sealing is required under varying thermal and mechanical conditions.

During installation, these fittings are pressed onto the pipe end using a certified pressing tool and then connected to a threaded component. The sealing is ensured by the EPDM O-ring and the metal-to-metal contact between the pressed sleeve and the fitting body. The operating temperature range and pressure rating must be considered when selecting the appropriate fitting for the application.

Technical parameters

The operating temperature range allows use in cold and warm water systems, while the maximum temperature of +120 °C makes it suitable for hot water applications. The nominal pressure of PN 16 indicates the fitting can handle medium-pressure environments. These parameters are crucial for ensuring the fitting is compatible with the system's design conditions and media.

Installation and connection

Installation requires a press tool and a threading tool. First, the pipe is cut to length and deburred. The correct press sleeve is selected and placed over the pipe. The pipe is then inserted into the fitting until the stop mark is reached. The press tool is applied to form a secure connection. For the threaded side, the fitting is screwed into the corresponding component with care to avoid cross-threading. After installation, the fit and alignment should be visually inspected, and the sealing should be tested under pressure to detect leaks. Common errors include incorrect press depth, insufficient press force, or using damaged sleeves.

Compatibility and accessories

This fitting is compatible with press systems using stainless steel pipes of the same material grade. It connects with internally threaded components such as valves, manifolds or other fittings. To complete the installation, additional accessories such as press tools and threading tools are required. Related products include other IVAR connection fittings in the IVN60, IVN61, IVN62 and IVN64 series.

Technical background for designers

The fitting operates by forming a metal-to-metal seal through the press process and an additional EPDM O-ring seal. The stainless steel grade 1.4404 (AISI 316L) offers high corrosion resistance and is suitable for aggressive media. The EPDM O-ring provides flexibility and sealing under thermal expansion. When designing a system, ensure the fitting is compatible with the pipe material and that the operating conditions match the specified parameters. The long-term performance depends on correct installation, material compatibility and system design.

Service and operation

Periodic visual inspections are recommended to identify signs of wear, corrosion or leakage. If any issues arise, the affected fitting should be replaced immediately. There are no scheduled service intervals provided in the technical data. During operation, ensure the system remains within the specified temperature and pressure limits to prevent premature failure.
