Pneumatic Caulking Gun 310 / 400 / 600 ml with Regulator
Key points
- Adjustable regulator dials bead speed precisely
- Trigger quick exhaust stops the bead with no drips
- Split piston and safety cord prevent pop-out loss
- Aluminium body is drop-resistant and will not stick to glue
- Hard-glue and soft-glue versions cover cartridge and sausage
- Handles window, curtain-wall and auto-repair sealing where a steady bead matters more than speed
- Body shops can lay a consistent seam sealer bead down a full panel length
- HVAC duct fabricators can lay a sealant bead along a flange run with the 600ml barrel, so a long joint is sealed in a single pass

Product detail
All-metal pneumatic caulking gun for professional sealing work, running on 3-6 kg of shop air. The body uses aluminium front and rear covers, an aluminium tube and a screw-fixed metal clamp that can be stripped down for maintenance. Two physically distinct product lines cover the main adhesive formats: hard-glue models such as UM-220 and UM-230 use air-pressure direct push with a spring plate and no piston for 310ml plastic cartridges, while soft-glue models such as UM-300 and UM-460 use a split rubber piston with a safety cord for sausage packs, sealing tightly and preventing the piston from popping out. Barrel capacity runs to 310ml, 400ml and 600ml, with a tube inner diameter of about 50mm and sausage length limits of 25cm at 400ml and 35cm at 600ml. Net weight is 0.85kg on the 310ml hard-glue model and 1.0kg on the 600ml soft-glue model. An adjustable barometer controls output: lift the knob and turn left to reduce or right to increase pressure. Releasing the trigger opens a quick exhaust port that stops the bead instantly without drips, and the rubber air hose resists wear and corrosion. The ergonomic non-slip handle and threaded front cover keep long single-handed sessions comfortable and leak free. Suited to sheet metal, window and door installation, curtain wall sealing, automotive repair and general construction jointing with silicone, structural and silicone sealants. Production lines can hang the gun on a balancer over the bench, so the operator lays a bead on a repeatable line length without holding the tool's weight through a shift. Fitters use it to lay a bead down a long glazing channel or a precast panel joint where a manual gun would need a regrip every few metres, and the regulator lets the flow be trimmed for a thin sealant or a thick mastic.
