Best pipe sealants

For high-quality and uninterrupted operation of heating, water supply and sewerage systems, organized without welding and special soldering iron, you need a good sealant. It guarantees reliable insulation when several elements are connected and there are no additional fasteners, reducing the likelihood of leakage. Its use is especially noticeable in case of unstable soil, temperature extremes, temporary "aging" of materials in the private sector. Tightness at the joints is ensured only by the best pipe sealants, which are presented in the rating.

Rating of pipe sealants

Substandard formulations can lead to leakage. To avoid such a situation, a rating of the best pipe sealants was left. It was based on consultations with plumbers, sellers and customer reviews.

The selection took into account the following parameters:

• Type - acrylic or silicone;
• Composition - acidic or neutral;
• Volume and type of packaging;
• Drying time;
• Resistant to UV rays, moisture, bacteria, fungi, vibrations, high pressure;
• Color and consistency;
• Smell;
• Application area;
• Maximum and minimum operating temperature;
• Processing material - metal, plastic, wood, ceramics, glass, concrete or stone;
• Chemical resistance;
• Possibility of contact with drinking water.

Versatility and value for money were also important criteria. More than 30 applicants took part in the selection. After detailed analysis and comparison, 10 sealants were selected. For convenience, they are divided into 2 categories: for metal and plastic structures.

Sealants for metal pipes

Neutral or acidic silicone sealants are used to prevent leakage in metal pipes. They are easy to use, durable and have a wide range of applications. Acrylic products are very popular. Their advantage is their anaerobic properties, due to which air intake is not required for curing. The experts at expertpro.techinfus.com/en/ carefully studied the characteristics of 20 nominees. After comparing them, based on the best resistance to weather and mechanical stress, 7 winners were selected.

How to choose a pipe sealant

When choosing a pipe sealant, it is important to pay attention to its type, recommended processing material, packaging, base in the composition.

A type

There are silicone (neutral and acidic) and acrylic pipe sealants. The first type is a great option for those who value versatility. It has a proven track record in sealing and sealing metal and plastic structures. The joint formed is elastic and resistant to deformation. This product is not suitable for overpainting.

The second type is suitable for those who want to get a high-quality connection of metal products, not subject to increased pressure, vibrations and temperature changes.

Processing material

Acrylic products are only suitable for metal. If you need to use a product for different materials, it is better to pay attention to the universal types.Silicone compounds meet this criterion. They do well with wood, glass, ceramics, metal and plastic, some connect stone and concrete.

Packaging

The packaging can be an aluminum foil tube or cartridge. In the first case, the agent is removed with the help of hands. The most comfortable use is the cartridge. It is equipped with a movable bottom that moves as the substance escapes and a special tip for easy application.

The basis

The product can be based on silicone or acrylic polymers. An acid-based silicone is suitable for those who wish to obtain isolation in a specific area. But it should be borne in mind that it enters into a chemical reaction with some materials (neoprene, EPDM, etc.). A neutral type is a good option for those who value versatility, as it adheres to almost all surfaces.

Acrylic-polymer base is suitable for those who want to obtain maximum resistance to vibration and high pressure. Its plus is that there is no need for oxygen, the minus is that it is suitable only for metal structures.

Features:

Basically, sealants are suitable for both outdoor and indoor use. But there are formulations that specialize in a certain type. So, in products for internal processing, additional substances are used that protect the seams from corrosion, bacteria and fungi.

It is important to pay attention to the color of the liquid, because if it is incorrectly selected, the appearance of the structure can significantly deteriorate.

In the case of using a sealant for connecting pipes in difficult conditions, heat resistance, frost resistance, elasticity, resistance to vibration, UV rays and pressure are required.

Which pipe sealant is best

The choice of pipe sealant largely depends on its resistance to temperature extremes:

• For those who appreciate the versatility and the ability to operate joints at temperatures from -40 to + 100 ° C, Penosil Universal Silicone or Stayer Master neutral are suitable.
• If there is a need for a temperature range from -40 to + 180 ° C, it is better to pay attention to the multifunctional Kudo KSK sanitary with protection against fungi and bacteria.
• Fome Flex Thermo (-65 to + 260 ° C) has the best thermal resistance and supports a wide range of applications.
• Optimum temperature performance (-40 to + 100 ° C) is supported by the universal Remontix.
• For those who want to get optimal heat resistance, versatility and protection against mold and bacteria, a good option would be Bostik Sanitary Silicone A (-40 to + 180 ° C) or Kim Tec 101e / Kim-Tec 101E Silicon Acetat (-50 to + 180 ° C).
• If the requirements for thermal stability are not high, you should choose Repair 100% (from -40 to + 100 ° C), processing a variety of materials.
• For those who want to buy a special composition for metal coatings, it is better to purchase Tangit Metalock (-55 to + 150 ° C) or Efele 133 water pipe sealant (-60 to + 150 ° C).

The high-quality composition of the sealant will provide a strong and elastic connection for many years. The TOP contains the most versatile products that are resistant to atmospheric and mechanical influences.
