A leaking thread in a plumbing system is a problem that can cause a lot of trouble in both domestic and industrial water or gas systems. Leaks not only cause water or gas losses, but can also lead to more serious damage. Below we present practical tips on how to effectively seal a leaking thread and ensure long-term tightness of the installation. You will learn which methods of sealing threads are the most effective and how to use them correctly.

Why is plumbing thread leaking?
Leaks in threaded connections can be caused by various reasons. Most often, it is the result of inaccurate assembly, damage to the thread during installation or natural wear of sealing elements . In the case of installations exposed to large fluctuations in temperature or pressure, the problem of leaks may appear over time, even if the connection was initially tight.
Another important issue is the selection of appropriate materials. Incorrect matching of the sealant to the type of installation (e.g. water or gas) can result in the rapid appearance of leaks. That is why it is so important to use materials dedicated to specific applications when sealing threaded connections.
The most popular methods of sealing threads
In hydraulic practice, there are several proven methods of thread sealing. Each has its advantages and works best under certain conditions. The most popular techniques include:
- Sealing with tow - a traditional method using tow , particularly effective for larger pipe diameters.
- Teflon tape - a universal solution where Teflon tapes are used, ideal for smaller diameters and connections that may require disassembly.
- Adhesives and sealing pastes - modern preparations ensuring high tightness and resistance to various factors.
The selection of the appropriate method depends on the type of installation, the material from which the pipes are made, and the operating conditions of the system.
How to seal threads with hemp?
Sealing threaded connections with hemp is a traditional, but still very effective method. To properly seal pneumatic or hydraulic threads with hemp, you should:
- Clean the thread surface thoroughly.
- Wind the tow onto the shank side of the pipe in the direction of the threaded connections.
- Distribute the fibers evenly along the entire length of the thread.
- Cover the tow with a thin layer of sealing paste.
- Screw in the element, being careful not to damage the hemp.
This method works particularly well in water and gas installations, where high tightness of the connection is required.
Proper thread sealing with Teflon tape
Teflon tape , also known as Teflon, is a universal thread sealant that works great in both water and gas installations. To properly apply Teflon tape:
- Clean the thread surface thoroughly.
- Start wrapping from the end of the thread, in the direction opposite to the direction of screwing.
- Apply 3-4 layers of tape, stretching it slightly.
- Make sure the tape evenly covers the entire thread.
- Be careful not to use too much tape, which could make it difficult to twist the connection properly.
Teflon tape is particularly useful for connections that may require periodic disassembly, as it does not permanently bond the components.
Sealing the thread with sealing glue
Modern adhesives and sealing pastes are an advanced solution that provides not only high tightness, but also resistance to various chemical factors and temperature. To properly apply the sealing adhesive:
- Clean and degrease the thread surface.
- Apply a thin layer of glue to the first few threads.
- Spread the glue evenly along the entire length of the thread.
- Connect the components, tightening them according to the manufacturer's recommendations.
- Allow to dry for the time specified in the product instructions.
Adhesive sealants are particularly effective in installations exposed to vibrations or frequent temperature changes.
Thread seals at the Onninen wholesaler
In the offer of the Onninen plumbing wholesaler of thread sealants you will find a wide selection of professional materials and tools. From traditional sealing pastes and tows, through high-quality Teflon tapes, to advanced adhesives and sealants - everything you need to effectively seal a leaking thread.
The key to effective sealing is not only the selection of the right material, but also its correct application. Therefore, in addition to products, they also offer expert advice on the selection and use of sealing materials.
It is worth remembering that different types of installations may require specific solutions. For example, in the case of gas installations, it is necessary to use materials with appropriate certificates. In turn, in drinking water installations, products that do not affect the quality of the water should be used.
Whether you are a home repairer or a professional plumbing company, Onninen has everything you need to effectively seal threaded connections. From classic solutions to state-of-the-art technologies, Onninen guarantees the quality and reliability of its products.
Sealing a leaking thread is a task that requires the right knowledge and tools. Whether you choose traditional hemp, universal Teflon tape or advanced sealing glue, the key to success is precision and careful execution.
Sealing threaded connections is a key aspect of hydraulics and pneumatic systems. Whether you’re working with metal pipes or plastic components, remember to apply the sealant correctly to the shank side of the pipe in the direction of the thread. Sealing thread or Teflon tape are popular choices, but it’s important to match the method to the specific application. Sealing threads with Teflon tape will work well in many situations, but sometimes traditional thread sealing with hemp and paste may be more appropriate.
Proper thread seals are important not only in water pipes, but also in connections in compressors or other industrial equipment. Pay attention to the edges and quality of the threading to ensure a perfect seal. Always assess the installation for tightness after the work is completed. THIS will help to avoid later problems.
