Silicone Caulking Tool, Classic Black
Scrape out stubborn old beads and shape fresh sealant around sinks, tubs, and window frames with one hand tool.
When a water line runs cold through the crawl space, stiff tubing fights back. We built this manual expander from aluminum alloy and hardened spring steel to flare the tube mouth so the fitting seats flat. It packs five head options and a pipe cutter into one latched box.
Price and stock live with the storefront and can move between visits.

Five separate head assemblies screw right onto the tool nose. Each segmented head expands outward together, widening the flexible sleeve and tubing wall so your barbed fittings slide in before the plastic snaps back.
The body is light aluminum alloy that will not drag your arms down overhead. Inside, a chrome-plated spring steel cone drives the spreading segments apart smoothly against the firm tension of the tube.
A clean square end makes a true joint. We drop a dedicated tubing shear into the molded tray beside the main tool, saving you from chasing a pocket knife across the floorboards.
Expanding dry tubing wears on metal cone faces. We pack a small tube of lubricant in the case so the expander segments slide out smoothly each time you squeeze the long handles together.
