Thread locking
Traditional locking methods cannot completely fill the gap between threads, but thread locking agents can achieve this
Thread locking agent can lock and seal threaded components, preventing them from occurringVibrationCorrosion or wear. But you must choose the appropriate thread locking agent based on the strength, shape, and disassembly of the component
How to choose thread locking agent
Whether used for heavy equipment and permanent components, or for fixing bolts and adjusting screws, Loctite thread locking agents can meet your requirements
Low intensity
Mainly used for adjusting screws, calibrating screws, instruments, and gauges. They require frequent disassembly and can be dismantled using manual tools
Medium intensity
Suitable for machine tools and presses, pumps and compressors, fixing bolts and gearboxes. They require regular disassembly and can be disassembled using manual tools
High intensity
More suitable for permanent locking components, heavy equipment, motors, and pumps. They rarely need to be disassembled and require local heating before disassembly
Thread locking agents have various appearances such as liquid and semi-solid, which can smoothly fill gaps without dripping or stains, and are suitable for overhead construction applications. Having a thorough understanding of your application can help select the appropriate thread locking agent
From practical application to final maintenance and disassembly, Loctite thread locking agent can withstand extreme temperature environments for a long time

Pipe thread seal
Leakage causes unexpected shutdown of equipment, liquid pipe thread sealant prevents leakage without fear of pressure
Eliminate leakageEnsure production without interruption
Pipe thread sealant can fill the gaps between threaded parts, achieving instant low-pressure sealing, preventing liquid and gas leakage, and avoiding losses caused by unexpected shutdowns. Letai has multiple types of pipe thread sealants, and you can choose the appropriate sealing product based on the system material and thread type
How to choose pipe thread sealant
Loctite pipe thread sealant can meet the needs of various pipeline systems
Metal
In the absence of air, the sealant can solidify into a hard solid upon contact with metal
Plastic
Suitable for plastic threads or plastic/metal substrate combinations

Threads can be divided into two categories. The American standard taper pipe thread (NPT) is widely used in the United States and Canada, requiring the use of low strength pipe thread sealant for easy disassembly. British Standard Cone Pipe Thread (BSPT) is mainly used in countries other than the United States and Canada, and requires the use of high-strength pipe thread sealant to seal the interface
Pipe thread sealant has various appearances, including liquid, paste, and solid. Various types of sealants are suitable for different applications. Liquid sealants are suitable for sealing gaps in threaded joints, while paste and solid sealants are more suitable for high-pressure applications that require drip prevention or immediate sealing

To achieve long-term stable sealing effect, the sealant must completely fill the gap and withstand liquids and/or gases, as well as temperature and pressure in the on-site environment. Loctite offers a wide range of flat sealing products that can be paired with various flange materials to seal gaps of different sizes
How to choose flat sealing products
Rigid machined flange
There is usually no gap between the surfaces of rigid machined flanges, allowing for face-to-face contact between metals. For this type of component, anaerobic planar sealant is the best choice as it can provide the highest strength sealing effect

Elastic adhesive
Adhesive of multiple substrates to achieve high ductility, suitable for joints with frequent movements
Adhesive and sealingFearless of dynamic loads
Elastic adhesives and sealants are mainly used to absorb or compensate for dynamic loads, suitable for long-lasting and firm bonding of different types of substrates, and suitable for filling large gaps. The sealing layer formed by curing has elastic properties, which are both waterproof and UV resistant. The strong bonding effect can withstand high tensile and impact forces, and withstand cold and hot cycles, reducing or absorbing stress for substrates with different coefficients of thermal expansion
How to choose elastic adhesives and sealants
Although all elastic adhesives and sealants can achieve bonding and sealing effects, some products have higher tensile strength and are therefore more suitable for bonding applications. On the contrary, if the product has better extensibility, it is more suitable for sealing applications
Modified silane based adhesives and sealants can be painted immediately after application, while silicon-based adhesives and sealants cannot be painted
We suggest that you choose the appropriate elastic adhesive and sealant according to the operating temperature of the terminal device
Two component elastic adhesive and sealant can cure quickly& nbsp; & nbsp; & nbsp;

Strong adhesionSpeed up production
UV curable adhesives are highly suitable for production applications that require rapid curing, typically used for assembling glassware, speakers, optical instruments, electronic components, and disposable medical devices. When selecting adhesives suitable for specific applications, the main factors to consider include the light transmission ability of the assembled components (so that ultraviolet/visible light can be transmitted to the adhesive layer), whether a rigid or flexible adhesive layer is needed, and the type of substrate to be bonded
How to choose light curing adhesive
Visible light curing adhesive is suitable for transparent substrates that are resistant to ultraviolet radiation.

< 0.006 inches
Usually, low viscosity retaining adhesive is suitable for gaps below 0.006 inches. These are typical gap fit and interference fit, commonly used in cold shrink assembly
0.006-0.010 inches
When filling gaps of 0.006 inches or more, a higher viscosity retaining adhesive should be used to ensure the filling effect. When filling the sliding fit, this type of retaining adhesive should be used

To achieve long-term stable sealing effect, the sealant must completely fill the gap and withstand liquids and/or gases, as well as temperature and pressure in the on-site environment. Loctite offers a wide range of flat sealing products that can be paired with various flange materials to seal gaps of different sizes
How to choose flat sealing products
Rigid machined flange
There is usually no gap between the surfaces of rigid machined flanges, allowing for face-to-face contact between metals. For this type of component, anaerobic planar sealant is the best choice as it can provide the highest strength sealing effect
Stamping or flexible flange
The thinner the stamped metal flange, the larger the gap that needs to be filled, and the greater the bending amplitude that may occur during use. For this type of component, silicone flat sealant can achieve ideal sealing effect
