MEETOOT 3 Sets 10 Ounce Refillable Empty Caulk Tube with Leak Proof Cap Spare Pointed Rubber Tip DIY Caulking Cartridge Suitable for Window Sealing Tile Repair Car Maintenance

Package contents: 3 refillable empty tubes 3 sealed rear caps (with piston) 3 sealed front caps 3 spare pointed nozzles Important notes: Initial use: Before first filling, unscrew the rear cap, remove the piston, and fill the tube with adhesive from the rear end. Replace the piston into the rear cap, screw it tight, then insert into the caulking gun for use. Fill appropriately: Fill no more than 95per cent of the tube's capacity to allow sufficient space for smooth piston movement. Seal Promptly: After each use, immediately clear any residual adhesive from the nozzle tip and replace the front cap to prevent air ingress causing curing. Cleaning and maintenance: When switching to different colours or types of adhesive, promptly clean the tube interior. Rinse with clean water (for water-based adhesives) or a specialised cleaner (for oil-based adhesives), allow to air dry, then reuse. Safety precautions: Keep adhesive tubes away from open flames or high-temperature environments.
