Foam gun is a professional construction tool matched with polyurethane foam sealant. The built-in flow valve precisely controls glue output for uniform and controllable filling. The main body is made of thickened aluminum alloy or stainless steel, with forged pure brass threaded joints for anti-corrosion and zero leakage. Premium models are equipped with internal Teflon (PTFE) non-stick coating on valve and barrel, featuring anti-adhesion, easy cleaning and anti-clogging performance. The series includes standard metal foam guns and extended long-barrel versions, widely used for door & window gap filling, wall hole sealing, pipeline insulation, thermal filling and home decoration crack repair. It delivers stable, smooth glue flow, cuts foam waste and improves sealing efficiency greatly.
1. Main Body: Thick seamless aluminum alloy & integrated stainless steel, impact-resistant, pressure-resistant and anti-corrosion, free of deformation and leakage after long-term use.
2. Brass Thread Connector: Forged pure copper joint with anti-oxidation and wear resistance, tightly matched with foam can to avoid pressure loss and glue leakage.
3. Teflon PTFE Coated Valve & Barrel (Standard on Premium Versions): Smooth inner surface prevents cured foam adhesion, drastically reducing clogging frequency. Intermittent work requires no frequent solvent flushing for long service life; high temperature and chemical resistance extend tool lifespanswel.ie.
4. Replaceable Brass Nozzle: Detachable thickened copper tip, wear-resistant and deform-proof, compatible with extended thin nozzles for ceiling and deep narrow gaps.
5. Anti-slip Nylon Grip: Ergonomic handle reduces slipping and wrist fatigue during long-hour operation.
1. Rear flow control knob allows stepless glue output adjustment, suitable for both tiny cracks and large holes to avoid overflow waste.
2. Teflon coating on premium models prevents foam curing adhesion, cutting cleaning work and clogging breakdowns.
3. Fully detachable all-metal split structure enables thorough cleaning of residual foam inside the barrel and valve.
4. High-sealing brass joint prevents glue curing blockage during idle storage with simple daily maintenance.
5. Extended barrel models reach deep ceiling gaps and wall holes to eliminate blind operation zones.

1. Only use matched tubular polyurethane foam; incompatible corrosive adhesives are prohibited.
2. Test glue output with dry firing before formal work for first use or long storage to guarantee smooth pipeline flow.
3. Rinse valve and barrel with dedicated foam cleaner after use for standard metal models; Teflon coated versions only need residual foam purging before storage.
4. Store the gun with nozzle facing down to avoid glue backflow and valve blockage.
5. Avoid heavy impact on brass nozzle; deformation will cause uneven glue output and leakage.
