Stopper, 1/2"

Product detailed description

This stopper is commonly used in residential and commercial buildings for sealing pipe ends during installation or maintenance of heating, plumbing and sanitary systems. It ensures a secure and leak-free closure in systems where temporary or permanent sealing is required. Installers typically use this component in conjunction with valves, fittings and pipe segments to prevent contamination or fluid loss during assembly.

The 1/2 inch size makes it compatible with standard pipe diameters in low-pressure applications. The nickel plating provides corrosion resistance, making it suitable for environments where moisture or chemical exposure is present. The EPDM sealing ring ensures a tight seal under normal operating conditions.

Technical parameters

Installation and connection

Before installation, ensure the pipe end is clean and free from debris. Apply a small amount of thread sealant or PTFE tape to the male threads to enhance the seal. Insert the stopper into the pipe and hand-tighten before using a wrench to achieve a firm fit. Avoid over-tightening to prevent damage to the sealing ring or the plating. Check that the stopper is fully seated and does not wobble. Common installation errors include using the wrong thread type or failing to clean the connection surfaces properly.

Compatibility and accessories

This stopper is compatible with systems using nickel-plated brass fittings and EPDM seals. It is designed for use with pipes and fittings of the same nominal diameter and thread type. For complete sealing, ensure that the mating female thread is also clean and undamaged. No additional accessories are required for standard installation.

Technical background for designers

The stopper operates as a simple sealing device, preventing fluid flow through a pipe when installed. The nickel-plated brass body offers good mechanical strength and corrosion resistance, while the EPDM sealing ring provides flexibility and durability. The PN 10 rating and +120°C operating limit make it suitable for use in central heating systems, hot water supply lines and similar applications. Long-term performance depends on correct installation, compatibility with system media and regular inspection for signs of wear or leakage.

Service and operation

During routine maintenance, inspect the stopper for signs of corrosion, wear or leakage. If the sealing ring is damaged or degraded, it should be replaced. No scheduled service intervals are specified for this component. Ensure that the stopper is removed and reinstalled with care to avoid damaging the sealing surface or thread.

Frequently asked questions

Can this stopper be used in hot water systems?
Yes, it is suitable for systems with operating temperatures up to +120°C, making it appropriate for hot water and heating applications.

Is it compatible with other nickel-plated brass fittings?
Yes, provided the thread type and size match. The stopper is designed to work with standard male threads of the same specification.

What should be done if the stopper starts leaking after installation?
Remove the stopper and inspect the sealing ring and mating surfaces for damage. Reapply thread sealant and reinstall carefully to prevent over-tightening.

Can it be used in high-pressure systems?
No, the nominal pressure rating is PN 10, which means it is not suitable for systems exceeding 10 bar operating pressure.
