Bonstone 2:1 Cartridge Gun Adaptor

Description

The Bonstone 2:1 cartridge gun adaptor supports **syringe barrel** and cartridge dispensing setups when a two-part adhesive package needs the correct mechanical fit before material is pushed through the mixer. It is a small service part, but it matters on jobs where a cartridge ratio, gun frame, and plunger set must work together without forcing the package or wasting adhesive.

### Where this syringe barrel adaptor fits

Stone repair, restoration, and countertop fabrication teams often keep several Bonstone cartridge products in the same shop. Two-component epoxies, patching compounds, and knife-grade systems may use different cartridge ratios, and the applicator hardware has to match the package before the bead can be controlled. This adaptor is used with Bonstone cartridge gun setups that need a 2:1 interface. It helps bridge the gun to the adhesive package so the plungers drive both sides together and feed material toward the static mixer in the intended ratio.

The part is most useful when a shop standardizes on a preferred dispenser but still needs to run a 2:1 Bonstone cartridge for a specific repair compound. It also belongs in service kits for installers who travel with adhesive guns, mixer tips, and ratio hardware rather than bringing a separate applicator for every cartridge family. Keep the adaptor with the matching mixing nozzle, 2 part mixing nozzle, and jb weld mixing nozzle inventory only when those consumables are part of the same two-component setup.

### How this syringe barrel setup works

Before loading adhesive, inspect the gun frame, piston faces, retainer, cartridge nose, and mixer connection. The adaptor should seat squarely, with the cartridge held firmly enough that trigger pressure transfers into the plungers instead of cocking the package inside the frame. Once the cartridge is seated, purge a small amount of material, install the mixer, and dispense until the color and flow look uniform.

Discard the first small purge if the job requires a clean mixed bead. That practice helps remove unmixed material from the cartridge nose and gives the operator a better feel for trigger pressure before touching stone, concrete, or masonry. Do not force a cartridge that does not align. Ratio hardware is meant to guide the package, not correct a mismatched gun. If trigger pressure climbs suddenly, stop and check the mixer and cartridge nose before applying more force.
