Semco 350065 Model 350 Gun with 6 oz. Retainer

This Semco Model 350 Sealant Gun with 6 oz. (156cc) retainer is designed for quiet pneumatic application of sealants, adhesives, potting compounds and other materials packaged in Semco disposable cartridges or Semkit packages that are used for multi-component materials. Air hoses to operate the gun must be ordered separately.

Constructed of metal and engineered plastic parts, this durable gun is designed to withstand the rigors of the production workplace. The nickel plated retainers are affixed to the gun via a quick connect, secure bayonet lock feature permitting easy cartridge replacement. A regulating wheel on the handle is used to set the working pressure at the feed volume required.

Attach the air hose assembly to the compressed air source. Some applications may require the user to replace the quick release hose connector with a fitting compatible with local air supply hardware. Place the cartridge into the retainer and bayonet retainer adapter. Adjust the regulating wheel to set feed volume. When the trigger is depressed, air pressure pushes against the plunger in the cartridge. This allows for positive even dispensing of material. The material continues to flow until the trigger is released thereby permitting a drop, shot or bead to be accurately applied.

The amount of material dispensed is determined by the viscosity of the material, air line pressure, regulating wheel setting, nozzle or needle orifice size and the length of time the trigger is depressed. When all the material has been dispensed from the cartridge, twist the retainer to remove from gun. Then remove the disposable cartridge and nozzle. For smooth operation weekly, add a couple drops of air tool oil in the air inlet. Dispose of leftover material in accordance with local regulations and instructions on the material safety data sheet.
