Grommet - male thread - N - 15mm-R3/4" IVAR.IVN81

Product detailed description

This stainless steel grommet with a male thread is commonly used in professional heating, plumbing and industrial installations. It is suitable for connecting press fittings to threaded components in systems such as heating circuits, sprinkler systems, compressed air lines and solar installations. The grommet is designed for environments where reliable sealing and resistance to corrosion are essential, such as in commercial and industrial buildings. The component is typically installed by certified technicians who ensure proper alignment and secure connections to prevent leaks and maintain system integrity.

Its application is particularly relevant in systems where a transition from a press connection to a threaded connection is required. The grommet is often found in press-fitting systems that require compatibility with traditional threaded components. It is used in both new installations and system upgrades, ensuring compatibility with existing infrastructure. The material and design make it suitable for environments with fluctuating temperatures and moderate pressures.

Technical parameters

Material	Stainless steel class Wst. Nr. 1.4404 (AISI 316L), O-ring EPDM
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN81.1534
Brand	IVAR

The operating temperature range of -20 °C to +85 °C, with a maximum of +120 °C, allows for use in a wide range of environments, including those with seasonal temperature variations. The nominal pressure rating of PN 16 ensures the component can handle typical pressures in heating and plumbing systems. These parameters are essential for selecting the correct fitting for the intended application and ensuring long-term performance.

Installation and connection

The grommet is installed using a press tool to secure the press connection side, while the male thread is used to connect to a corresponding female thread. The connection size on the press side is 15 mm, and the threaded side is R3/4" (3/4 inch). During installation, it is important to ensure that the press connection is fully compressed and that the thread is properly aligned and tightened to prevent leakage. A common mistake is not compressing the press connection fully, which can lead to a weak seal. Technicians should also check that the O-ring is correctly seated and undamaged before final tightening.

Compatibility and accessories

This grommet is compatible with press-fitting systems using stainless steel pipes of the same material class. It is intended for use with EPDM O-rings, which are included as part of the fitting. No additional accessories are required for standard installation. It is important to ensure that the press tool used is compatible with the material and dimensions of the fitting to achieve a secure connection.

Technical background for designers

The grommet functions as a transition fitting between a press connection and a threaded connection. It is made from stainless steel class 1.4404 (AISI 316L), which offers high resistance to corrosion and is suitable for use in aggressive environments. The EPDM O-ring provides a flexible and durable seal, ensuring long-term performance. The integration of this fitting into a system depends on the system's pressure and temperature requirements. The material properties of the stainless steel ensure that the fitting can withstand thermal expansion and contraction without deforming or losing its integrity. The design allows for a secure and leak-free connection between press and threaded components.

Service and operation

Regular inspection of the connection is recommended to ensure that there are no signs of leakage or wear. The O-ring should be checked for damage or deformation, and the press connection should be verified for full compression. If any issues are detected, the fitting should be replaced to maintain system performance. No specific service intervals are provided in the technical data, but visual inspections are advised during routine maintenance.

Frequently asked questions

Can this grommet be used in solar heating systems?
Yes, the grommet is suitable for use in solar heating systems due to its temperature range and material properties.

Is the O-ring replaceable?
The O-ring is part of the fitting and is not designed to be replaced separately. If it is damaged, the entire fitting should be replaced.

Can this fitting be used with copper pipes?
No, the fitting is designed for use with stainless steel press pipes and is not compatible with copper.

What is the maximum operating temperature?
The maximum operating temperature is +120 °C, beyond which the fitting is not recommended for use.
