Grommet - male thread - N - 18mm-R3/4" IVAR.IVN81

Product detailed description

Stainless steel grommets with male threads are essential components in press and threaded piping systems for heating, plumbing, and industrial applications. These fittings are commonly used in residential, commercial, and industrial buildings to connect press pipes to threaded components such as valves, meters, and actuators. The IVAR IVN81.1834 model is designed for use in systems where a secure and durable connection is required under varying temperature and pressure conditions. Installers working on heating systems, sprinkler systems, or industrial piping will find this fitting suitable for its intended applications.

Proper installation of these grommets ensures system integrity and minimises the risk of leaks. The fitting is commonly used in press systems where the pipe is compressed into the fitting using a dedicated tool. The male thread provides compatibility with standard threaded components, making it a versatile solution for hybrid systems. It is important to ensure that the fitting is fully compressed and seated to the specified dimension to achieve a watertight seal.

Technical parameters

Installation and connection

Installation of the IVAR IVN81.1834 involves inserting the press pipe into the fitting and compressing it using a press tool until the indicator mark aligns with the specified dimension. The fitting has a 18 mm press connection and a R3/4" male thread. It is important to verify that the pipe is free from burrs and that the O-ring is undamaged before compression. Common installation errors include incomplete compression, which can lead to leaks, and using the wrong tool, which may damage the fitting or pipe. After compression, the final dimension should be checked to ensure the fitting is correctly seated.

Compatibility and accessories

This grommet is compatible with press pipes of the same nominal size and standard threaded components with R3/4" male thread. It is intended for use in press systems and should be connected to press pipes using the appropriate press tool. No additional accessories are required for installation, but it is important to ensure that the press tool is calibrated and suitable for the fitting. Related products include press pipes and other press fittings of the same nominal size.

Technical background for designers

The IVAR IVN81.1834 operates by compressing the press pipe into the fitting, creating a mechanical and hydraulic seal. The stainless steel construction provides resistance to corrosion and ensures long-term durability in a variety of environments. The EPDM O-ring provides a flexible and reliable seal that can accommodate minor misalignments. The material properties of 1.4404 stainless steel (AISI 316L) make it suitable for use in aggressive media and high-temperature environments. The integration of this fitting into a system depends on the system's pressure and temperature requirements, as well as the compatibility of the press pipe and threaded components.

Service and operation

Regular inspection of the fitting is recommended to ensure the integrity of the connection. Check for signs of wear, corrosion, or leakage, particularly at the O-ring and compression zone. If a leak is detected, the fitting should be replaced immediately. There are no scheduled service intervals specified for this fitting, but it should be replaced if it shows signs of damage or failure.
