LOCTITE thread sealant 55 - 160 m, roll

Product detailed description

Threaded connections are a common feature in plumbing, heating and gas distribution systems, particularly in residential and industrial buildings. Installers frequently encounter situations where metal-to-metal contact between threaded components is insufficient to prevent leakage, especially under pressure or vibration. Thread sealing tapes such as LOCTITE 55 are essential in such cases to ensure airtight and watertight seals without the need for additional gaskets or adhesives. This product is specifically recommended for use in systems where compliance with technical standards is required, including those governed by PTN 704 05.

Proper sealing is critical to the integrity of the entire system, especially in pressurized environments. The LOCTITE 55 tape is applied directly onto the male thread of a fitting before assembly, ensuring even coverage and preventing gaps that could lead to leaks. It is important to follow the correct application procedure to avoid over-tightening, which can damage the threads or cause the tape to compress unevenly. This product is suitable for both new installations and maintenance work in existing systems.

The technical specifications provided in the product table are essential for correct selection and application. The weight and EAN code assist in logistics and inventory management. The product code (LOCTITE55) ensures accurate identification when ordering or referencing in technical documentation. These details are crucial for integration into procurement and project management systems, particularly in large-scale installations where traceability is required.

Installation and connection

To apply the LOCTITE 55 thread sealing tape correctly, begin by cleaning the male thread to remove any debris or old tape. Wrap the tape clockwise around the thread, starting at the base, and apply enough layers to fill the thread grooves without overlapping excessively. Ensure the tape remains tight and does not fold during winding. After application, assemble the components by hand until they seat properly, then tighten using a wrench or pliers according to the manufacturer’s torque recommendations. Check the assembled joint for visible tape protrusion or misalignment, which could indicate incorrect winding or over-tightening. Common installation errors include applying the tape in the wrong direction, insufficient or excessive layers, and using damaged or expired tape.

Compatibility and accessories

This sealing tape is compatible with standard metal and plastic threaded fittings commonly used in gas and water systems. It is recommended for use with components designed for ALPEX-GAS systems. No additional tools are required for application beyond basic hand tools such as pliers or a wrench. However, for optimal results, it is important to use only the specified sealing material and avoid mixing with other types of tapes or sealants. No specific accessories are required for storage or handling, though the product should be kept in a dry environment away from direct sunlight or extreme temperatures.

Technical background for designers

Thread sealing tapes like LOCTITE 55 function by filling the microscopic gaps between threaded components, creating a barrier that prevents the passage of gases or liquids. The material is typically a polytetrafluoroethylene (PTFE)-based compound, known for its low friction and chemical resistance. When compressed during tightening, the tape conforms to the shape of the threads, forming a reliable seal without requiring additional mechanical force. Integration into the system depends on the design of the threaded components and the pressure conditions of the installation. Long-term performance is influenced by factors such as the quality of the threads, the accuracy of the winding process, and the environmental conditions to which the joint is exposed.

Service and operation

No specific maintenance is required for this product once it has been correctly applied and the joint is assembled. However, regular visual inspections of threaded connections are recommended to identify signs of wear, corrosion, or leakage. If a joint shows signs of failure, disassemble the connection, clean the threads, and reapply the sealing tape before reassembling. There are no defined service intervals for this product, as its performance is primarily dependent on correct installation and the absence of mechanical stress or environmental degradation.

Frequently asked questions

Can LOCTITE 55 be used in high-pressure water systems?
Yes, LOCTITE 55 is suitable for use in pressurized systems where a reliable seal is required. It is recommended for sealing threaded joints in accordance with technical standards.

Is LOCTITE 55 compatible with plastic fittings?
Yes, the tape is compatible with both metal and plastic threaded fittings, provided they are designed for use with sealing tapes.

How many layers of tape should be applied to a threaded connection?
The number of layers depends on the thread size and pitch. Typically, 2–3 layers are sufficient to fill the thread grooves and create an effective seal.

Can this sealing tape be used in gas systems?
Yes, LOCTITE 55 is recommended for use in gas systems, including those governed by PTN 704 05 standards.
