This ST-3® family Thread Sealant is a liquid applicant that once applied and allowed to dry, provides a elastic gasket around the threaded component, allowing threads to stay tight during severe vibration. The product not only provides a 2000 psi sealant gasket, but components can be taken apart and re assembled several times with a single application meaning it does not need to be cleaned off and re-applied after every use.

To use simply apply a thin film with a Q tip or similar applicator. Allow to air dry for a minimum of an hour. Thread product together and enjoy. After multiple assembly reassembly of the threaded component you will at some point need to brush the thread clean and reapply the process. This half ounce container contains ~50 applications of product.


Examples of application for Griffin products:

All pistol silencer end caps
Pistol booster housing outside threads only
Revolution booster outside extension threads
Sportsman end caps
Loosly threaded pistol barrel threads.

Do not use on pistol piston retainers or 3 lug rear caps. We recommend Horse Jipe™ 2300° for those applications.

    I love this stuff!! Keeps everything in place and keeps my Revo45 easier to maintain. Also easier to change configuration. And it lasts several cycles. I recommend it to everbody with a suppressor. Would and will buy again!!!

    This stuff is amazing. Put it on your pistol barrel threads and your silencer will NOT back off!

    Have not had time to test it under use; but upon initial application, it appears to do just exactly what it's advertised to accomplish.

    Silky smooth threads

    Amazing wonder sauce! Put this on my threads and allowed it to dry for a couple hours... threaded it in and it basically acts as a O ring style elasto polymer gasket. Locks out the carbon and it stays in place for multiple install/disasembly operations. Great product for keeping threaded parts clean, snug, and easily serviceable in the future.
