Empty Caulking Tubes

An empty caulking tube you fill yourself turns mixed epoxy into a controlled bead, so you can inject a void, run a seam or lay a fillet instead of smearing it with a mixing stick. Each tube holds about 10 fl oz and can be refilled as long as the epoxy inside has not cured.

One tube or a box of 24

Buy a single tube for a one-off repair: a soft spot to inject, a short seam, a fillet along one joint. The box of 24 suits a stitch-and-glue build or a day of repairs where you mix several batches and want a clean tube waiting for each one.

• Capacity: about 10 fl oz
• Packs: each, or a box of 24
• Jobs: epoxy injection, beads and fillets
• Refill it until the epoxy in the tube cures

Thickening epoxy so the bead holds its shape is laid out in the epoxy filler consistency chart.
