APT Sealant

APT Sealant is the State of the Art Thread Sealant.

APT will do what no other sealant will do.  APT is created with standard aerospace industry materials for use in sealing most threaded piping systems.

Key Unique Features

1. APT is effective with Stainless Steel, Carbon steel, Fiberglass, and Thermoplastics and more.

2. APT Sealant is Humidity and Water activated and works well in rainy weather.

3. It has been used as a secondary seal on piping systems, which utilize other primary sealing devices such as gaskets or O-rings.

4. There is no need to mix anything.

5. The piping system is ready for testing once the last connection is completed. The Sealant does not have to be cured to affect a seal. This combination of internal materials and curing create the optimum sealing characteristics for the threaded system being engaged.

6. APT comes in standard caulking gun size cartridges and can be easily dispensed and spread onto the threads of the piping system.

Basic Usage Guidelines

The material seals threaded systems with varying thread profiles and differing threads per inch. Be sure to engage the threaded system to the manufacturers recommended torque when using this sealant. The torque to seal is the same on this sealant as many other typical pipe sealants used on threaded systems.

The time to cure varies depending on Temperature and Humidity or Water application.

Since the Sealant comes in standard caulking gun size cartridges and can be easily dispensed and spread onto the threads of the piping system. Be sure that all foreign material has been removed from the threads prior to application of the sealant.  This can be accomplished with a dry rag, or normal solvents used for the removal of any oil or other residual material. Spreading the Sealant can be achieved using any spatula or flat device such as a paint stirrer or tongue depressor. The Sealant is to be applied to all threads, which are to be engaged. The sealant should typically fill the thread “root” (bottom or valley) to “crest” (top), in long threaded systems it may be best to only fill the threads ½ full, this can be accomplished by using a brush or similar instrument. This filling of the threads will maximize the sealing capability and it will also minimize the usage. Excess material left on the threads will only be wasted. Any excess left on the “Male” or “PIN” will wipe to the outside of the connection as it is engaged and be wasted. The excess left in the inside of the “Female” or “BOX” thread will be engaged into the inside of the connection. Once the connection is coated with sealant engage the connection within approximately 15  minutes, if one waits too long the material may be too stiff to engage especially in hot humid weather. Since the Sealant is Humidity or Water activated it will start to cure to a “rubber like” consistency as soon as it is dispensed from the caulking tube. Time varies depending on Temperature and Humidity or Water application. The higher the temperature and the higher the Humidity the faster the material will set up.

Cold weather use is only different in the fact that the Sealant must be kept warm, typically in the cab of a truck under the heater, until time for use. If the material is too cold it will not come out of the tube, typically below 50-60°F. Once the warmed material is dispensed and spread onto a cold thread a mixture of water and methanol can be sprayed onto the sealant to start the cure process (the blend of water and alcohol can be up to 50% methanol, to keep the water from freezing in colder temperatures). In cold weather the cure rate will slow, but again the sealant does not have to be cured to affect a successful connection.

Do not try to accelerate the curing process of the sealant by applying external heat. The piping system is ready for testing once the last connection is completed. The Sealant does not have to be cured to affect a seal, as there are components in the Sealant, which are the primary sealing materials and the curing of the base component are insurance for a successful connection. This combination of internal materials and curing create the optimum sealing characteristics for the threaded system being engaged.

APT Sealant is Humidity and Water activated and will start to cure to a “rubber like” consistency as soon as it is dispensed from the caulking tube. The higher the temperature and humidity the faster the material will set up. The system does not require the application of water to cure as long as there is humidity for the sealant to react with.  Without water application the cure will be significantly slower depending on temperature and humidity. The quickest cure rate about 10-15 minutes.
