⚡ At a Glance
- • Dispensing Control: Large flow control knob with secured back-screw for fine output adjustment
- • Best for: Tradespeople and DIYers who need neat, accurate foam application
- • Not ideal for: Occasional users who rarely use expanding foam
Large flow control and a secured back-screw enable accurate bead size and access to tight spots. Valve purge removes leftover foam so no detergent cleaning is required, while a replaceable smooth nozzle prevents drips.
Precise, controlled application, thanks to large flow control knob
A sizeable flow control knob combined with a secured back-screw lets users dial foam output finely, reducing sudden surges. The mechanism allows steady output even when reaching awkward corners.
Reduced waste and neater joints when sealing around windows, doors and service penetrations. Greater control helps achieve consistent fills in narrow gaps and tricky angles.
Simplified cleaning and turnaround, with a valve purge system
Turning the valve and pushing remaining foam through clears the gun internally, eliminating the need for detergent cleaning. The purge leaves minimal residue in the barrel and nozzle.
Faster finishing between jobs, with less downtime for maintenance. Fewer solvents are needed and there is reduced risk of blockages when returning to work.
Comfortable handling for prolonged use, with lightweight aluminium body and metal trigger
High-strength aluminium keeps overall weight low while maintaining durability, and a metal trigger offers reliable actuation that stops spraying immediately when released. A replaceable smooth dispensing nozzle reduces drips.
Less hand fatigue on long caulking or insulation runs, and tidy workspaces thanks to immediate cut-off performance. Suitable for repeated use on balcony doors, windows, bathtubs and air conditioning holes.
