In the process of repair and maintenance of various mechanisms (in my case, a bicycle), there is a need to lubricate difficult-to-access units, into which lubricant must be supplied metered or through small holes.
There was an idea to use a cartridge from silicone sealant or any other sealant designed to work with the “gun” applicator.

Sealant applicator
For work, it is advisable to use a fully used cartridge, with sealant not yet dried.
First of all, you need to squeeze out the piston, which is the cartridge.
To do this, in the applicator you need to unscrew the flat washer from the rod, which presses on the piston and tighten the nut in place. It is needed to increase the pressure area so that a part of the threaded rod does not push or damage the piston.
Then we insert the cartridge back and forth into the applicator and pressing the lever, we gradually squeeze the piston in the opposite direction.
In my case, there was a sealant on the walls of the cartridge and the piston stood across the cartridge, but I removed it with pliers.
After you remove the piston, you need to carefully clean the cartridge from the remnants of the sealant. Do not press hard on the part where the spout with thread is located, otherwise it may crack. Also, rinse off the removable tip from the rest of the sealant.
For ease of removal of sealant residues, you can cut the cartridge in half.
After the done manipulations, you can safely fill the cartridge with grease, in my case it was “Litol”.
Next, insert the piston into place, the excess oil can be squeezed back into the container with grease.
As a result, we get a cartridge filled with oil, which is convenient to use with the applicator.
You can also take a plastic tube of toothpaste, wash it thoroughly and fill it with oil using a cartridge. There are tips for such tubes of sealants. As a result, we get a traveling option for lubricating mechanisms in the field.
All successful experiments!
