About This

• THE ORIGINAL CAULK CAP. Trusted by pros and DIYers since 2014, our signature yellow caulk cap is the original tool for keeping open tubes sealed tight and fresh between jobs.
• JOIN 1 MILLION HAPPY CUSTOMERS. With over a million sold on Amazon, we're the go-to fix to stop costly tube dry-outs. Don't waste a $10 caulk tube—join the users who stretch every dollar.
• FITS SMOOTH & RING-LOCK NOZZLES. Works on smooth-top nozzles like GE Silicone and grooved ring-lock designs like DAP. Pushes in firmly for a secure, airtight seal on almost any standard caulk tube sealer application.
• PAYS FOR ITSELF IN ONE USE. Stop tossing half-used tubes. This reusable caulk saver replaces tape, nails, and cling wrap. Rinse clean in seconds, and just one saved tube pays for the cap.
• PIN & SEAL PREVENT PLUGS. The flexible yellow cap seals from the outside while the firm white pin fills the tip from inside. Together they prevent hardening on silicone, latex, or acrylic caulk. Your next squeeze starts clean instead of fighting a dried lump.
• USA-DESIGNED & PATENTED TOUGHNESS. Engineered in Washington and protected by U.S. Patent D740662. Our rugged industrial polymer caps handle drops, squeezes, and years of heavy toolbox use.
• FLEXIBLE & EASY TO PULL OFF. The soft yellow sleeve that seals tight is also easy to squeeze and pull off, even after long storage. No need to force it or twist it—just grab and pull. Rinse clean in seconds, and your caulk saver is ready to keep the next tube wet for months.
