Storage & Shelf Life
Proper storage of your J-B Weld 50165 epoxy syringe ensures it’s ready to perform when you need it most. After use, simply reseal the cap tightly to prevent air exposure and hardening. Store the syringe in a cool, dry place away from direct sunlight and moisture.
Unopened, the product typically has a shelf life of up to 3 years. Once opened, it’s best used within 6–12 months, depending on how well it’s sealed and stored. Check the consistency before each use — if it thickens or crystallizes, it’s time to replace it.
This long shelf life makes it ideal to keep on hand for emergency fixes or occasional DIY jobs.
