04/21/26
The B&G 3/8 Adapter (34605) is manufactured by B&G Equipment and is a accessory adapter for the B&G Robco Termite Tool. The B&G 3/8 Adapter (34605) is to be installed on the QCG or Quick-Change Gun for the purpose of attaching extension pipes to the end of the gun, specifically the 11/16 inch rod. If you are looking to use the QCG for injecting deeping into slab, this adapter is essential for set up.
Tools Needed
To install the B&G 3/8 Adapter you will need gloves and an adjustable wrench.
How to Use
- Step 1: Before starting, it is important to flush out any chemicals that could be left in the termite tool unit. To flush out the unit, simply add clean water and triple rinse. Once the unit is clean, you will need a clean working area preferably a table to dismantle the unit due to the many small parts.
- Step 2: Using the wrench, attach the B&G 3/8 Adapter to the end of the QCG gun and tighten to secure it in place. You can then attach the proper sized 11/16 rod and extension pipe, then finally the injection tip.
- Step 3: Reassemble the Robco Termite QCG gun, and then test out the gun by adding water to the unit and spraying to ensure there are no leaks.
Where to Use

The B&G 3/8 Adapter is used in the B&G Robco Termite Tool and is part of the Quick-Change Gun assembly. The Robco Termite Tool is used primarily for sub slab injections such as on a driveway.
When to Use
The B&G 3/8 Adapter will need to be replaced when it becomes damaged or worn. It is an essentially item to be able to use the extension pipes for injection.
Safety Information

Special Considerations

| Keith's Pro Tip | "When replacing the adapter, you should also check other parts on your Termite Tool to see if they need replacement as well. This will save you time so you make a replacement of hardware all in one shot rather than one part at a time." |
