Extend the life of your silicone sealant with Tube Nuts—innovative caps that keep your tubes sealed and ready whenever you need them. These reusable closures feature a dual-seal design: an internal stop that reaches into the nozzle combined with an outer perimeter grip that locks onto the tube for complete air-tight protection. Engineered to fit standard silicone and caulk tubes, they're built with reinforced heads that resist deformation under normal tightening.
Simply twist on and forget about it until your next project.
Perfect for DIYers and professionals alike, Tube Nuts eliminate waste, cut prep time, and deliver reliable performance job after job.
