Product Information

Full details

The Tajima Convoy SP12 Twin Thrust Super Heavy Duty Caulk Gun Tube is built for professionals demanding precision and power. Its key benefit is the high-powered 12:1 ratio combined with a 360-degree rotating barrel for comfortable and versatile application of sealants and adhesives. A potential caveat is its heavy-duty construction, which may be more than necessary for occasional DIY use. This caulk gun features a robust full metal mechanism, an auto-flow stop drip-proof system, and an integrated nozzle-unblocking pin, all designed for durability and clean operation with 310ml cartridges.

FAQs

What size cartridges does this caulk gun use?

This Tajima Convoy SP12 model is designed for standard 310ml (10.3 oz) caulk and sealant cartridges.

How does the auto-flow stop work?

When you release the trigger, the plunger rod retracts a small amount, releasing pressure and preventing excess material from extruding, thus stopping drips.

Is this caulk gun suitable for all types of sealants?

Its high 12:1 thrust ratio makes it suitable for a wide range, including high-viscosity materials. However, always check the sealant manufacturer's recommendations.

How do I unblock a clogged nozzle?

Use the extra-long integrated pin located on the gun body. Insert it carefully into the tip of the nozzle to clear any hardened material.

What is the advantage of the rotating barrel?

The 360-degree rotating barrel allows you to change the angle of application easily, improving reach, comfort, and precision, especially in confined or awkward spaces.

Is the handle material durable?

Yes, the handle is made from die-cast aluminum, providing a strong and comfortable grip for heavy-duty use.

Can I use this gun for very thick adhesives?

Yes, the 12:1 thrust ratio is specifically designed to provide the power needed for dispensing thicker, high-viscosity adhesives and sealants with less user effort.

Troubleshooting

Caulk is not dispensing

Ensure the cartridge is fully inserted and the plunger rod is firmly against the cartridge base. Check if the nozzle is clogged and use the integrated pin to clear it.

Drips after releasing trigger

Verify the auto-flow stop mechanism is engaging correctly. Ensure no debris is preventing the plunger from retracting slightly. Clean the mechanism if necessary.

Stiff or difficult trigger pull

Confirm you are using a compatible 310ml cartridge. High-viscosity materials naturally require more force. Ensure the nozzle is not excessively blocked, which can increase resistance.

Barrel rotates but feels loose

This is normal; the rotation mechanism is designed for smooth movement. Ensure the main plunger mechanism engages the cartridge securely.

Pros and Cons

Pros

  • Exceptional durability due to full metal construction.
  • Precise application control with the high 12:1 thrust ratio.
  • Reduced mess and waste thanks to the auto-flow stop feature.
  • Versatile handling with the 360-degree rotating barrel.
  • Integrated tools for quick nozzle clearing.

Cons

  • May be overkill for light-duty or infrequent use.
  • Its heavy-duty build can add weight compared to lighter models.
  • Requires a firm trigger pull for very thick materials, even with the high ratio.

Setup, Compatibility & Care

Setup: This caulk gun is ready for use out of the box. To load a 310ml cartridge, pull the trigger mechanism back completely, insert the cartridge into the barrel with the nozzle end facing forward, and then squeeze the trigger gently until the plunger rod engages the cartridge end.

Compatibility: The Tajima Convoy SP12 is designed to work with standard 310ml (10.3 oz) caulk and sealant cartridges.

Care: After each use, ensure the auto-flow stop mechanism is functioning. Clean any excess material from the barrel and plunger rod with a damp cloth. For long-term storage, it's recommended to clean the exterior and store it in a dry place. Periodically check the plunger rod for debris and wipe clean. Avoid excessive force on the trigger if the gun feels stuck; check for obstructions or a clogged nozzle.
