Grommet - male thread - N - 35mm-R5/4" IVAR.IVN81

Product detailed description

Transition fittings are essential components in modern pipe systems where different connection methods meet. This stainless steel transition fitting allows secure connection between press-fitted stainless steel pipe and externally threaded components. It is commonly used in heating systems, sanitary installations, fire suppression systems, compressed air systems and industrial applications where reliable, corrosion-resistant connections are required. Installers working on commercial buildings, residential complexes and industrial facilities will find this fitting suitable for connecting various system components.

The fitting ensures tight, durable connections in systems handling water, steam, inert gases and other media. Its design enables straightforward integration into existing pipe networks while maintaining system integrity and preventing leaks. The EPDM sealing ring provides effective sealing against media commonly found in technical installations.

Technical parameters

Material	Stainless steel grade 1.4404 (AISI 316L), EPDM sealing ring
Code	IVN81.3514
Brand	IVAR

The stainless steel grade 1.4404 (AISI 316L) offers high resistance to corrosion and is suitable for aggressive media. The EPDM sealing ring ensures compatibility with a wide range of fluids. These parameters are crucial for proper sizing and selection based on system requirements and media characteristics.Installation and connection To connect the fitting, first prepare the press-fitted pipe end according to manufacturer guidelines. Ensure the external thread is clean and free from debris. Apply even pressure during tightening to avoid damaging the sealing ring. Check the alignment of the connection to prevent stress on the joint. Common installation errors include over-tightening, which can deform the sealing ring, and using incorrect thread lubricants that may degrade the EPDM material. Always verify the connection for leaks after installation.Compatibility and accessories This transition fitting is compatible with standard press-fitted stainless steel piping systems. It requires matching press tools and sleeves for the 35mm pipe size. When installing, ensure all components are from the same system to maintain compatibility and performance. No additional accessories are required for basic installation, though appropriate tools for press connections are necessary.Technical background for designers The fitting operates as a mechanical transition between two different connection technologies. The stainless steel body provides structural strength and resistance to thermal expansion. The EPDM sealing ring forms a flexible, gas-tight barrier between mating surfaces. Proper integration into the system depends on correct sizing, alignment and media compatibility. Long-term performance is influenced by operating temperature, media composition and installation quality. Avoid using incompatible lubricants or sealants that could degrade the EPDM material.Service and operation Routine inspection should focus on the integrity of the connection and the condition of the sealing ring. Check for signs of leakage, corrosion or mechanical damage. If the connection shows any signs of failure, disassemble and inspect the sealing surface. Replace the EPDM ring if it shows signs of wear or deformation. No specific service intervals are defined for this component.Frequently asked questions

Can this fitting be used with press pipes of other manufacturers?
Use only with press pipes and tools from the same system to ensure compatibility and performance.

Is the EPDM sealing ring replaceable?
The sealing ring is integrated into the fitting and is not designed for separate replacement.

What thread standard does this fitting use?
The external thread follows the R5/4 standard for gas and fluid connections.

Can this fitting be used in high-temperature steam systems?
It is suitable for steam systems provided operating conditions remain within the material specifications of the stainless steel and EPDM seal.
