Cleaner lines start with steady feed. The sealant gun 400ml uses a rigid cradle, tempered rod and smooth‑action trigger to push product evenly for consistent beads. A quick‑release lets you stop flow cleanly to avoid tails at the end of a run, and the built‑in pin clears blocked nozzles without rummaging for tools. Whether you’re sealing windows, setting sanitary ware or bonding trims, the sealant gun 400ml helps you work tidily and at pace, leaving joints that look as good as they perform.
