Brass plugs are commonly used in heating, plumbing and sanitary systems to seal pipe ends during installation or maintenance. They are often found in residential, commercial and industrial buildings where temporary or permanent closures are required. Installers and technicians use these components to block off sections of pipe during testing, repairs or system shutdowns. The plug must be compatible with the system’s pressure and temperature conditions to ensure safe and leak-free operation.

Proper selection of a brass plug is essential to avoid system failures or leaks. The plug must be installed in a way that ensures a tight seal and maintains the integrity of the system. It is typically used in systems where sealing is required for inspection, maintenance or temporary shutdowns. The plug must be compatible with the pipe’s thread type and size to ensure a secure fit.

Brand	IVAR

The plug is rated for a maximum pressure of 1.5 MPa and a maximum operating temperature of 110°C. These parameters are critical for ensuring the plug can withstand the conditions of the system it is installed in. When selecting a plug, the installer must verify that the system’s operating pressure and temperature do not exceed these limits. Exceeding these values may lead to failure or deformation of the plug.

Installation and connection

The plug is designed for external thread connections. Before installation, the thread on the pipe must be clean and free of debris to ensure a proper seal. The plug is screwed into the pipe until it is fully seated. It is important to apply a suitable thread sealant or tape to prevent leaks. Common installation mistakes include over-tightening, which can damage the plug or the pipe, and using the wrong thread type or size. Always verify the thread type and size before installation.

Compatibility and accessories

This brass plug is compatible with systems using external thread connections of 1 inch. It is typically used in conjunction with sealing compounds or thread tape to ensure a leak-free connection. No additional accessories are required for standard installation. When replacing or repairing a system, it is important to ensure that the plug is compatible with the existing pipe and fittings.

Technical background for designers

The brass plug operates by creating a mechanical seal through the threaded connection. The material, brass, is chosen for its durability, corrosion resistance and ability to maintain a tight seal under pressure. The plug is integrated into the system by screwing it into the pipe’s external thread. The service life of the plug is influenced by the system’s operating conditions, including pressure, temperature and the presence of corrosive media. Proper installation and regular inspection are key to maintaining the plug’s efficiency and longevity.

Service and operation

Regular inspection of the plug is recommended to ensure it remains in good condition. Check for signs of wear, corrosion or leakage. If any issues are detected, the plug should be replaced. No specific service intervals are provided for this model. During operation, ensure that the system pressure and temperature remain within the specified limits to avoid damage to the plug.

Frequently asked questions

Can this plug be used in high-pressure systems?
Yes, the plug is rated for a maximum pressure of 1.5 MPa. It is suitable for use in systems operating within this pressure range.

Is the plug suitable for hot water applications?
Yes, the plug can be used in systems with a maximum operating temperature of 110°C, making it suitable for hot water applications.

Can the plug be used with internal thread connections?
No, this model is designed for external thread connections. Using it with internal threads may result in an improper seal or damage to the plug.

What type of sealing compound is recommended for this plug?
Thread sealant or PTFE tape is recommended to ensure a leak-free connection. The choice of compound depends on the system’s requirements and the installer’s preference.
