Bonstone Long Nozzle, Small (450ml Cartridges)

Description

The Bonstone long nozzle in the small size extends reach for injecting low-viscosity stone repair epoxy deep into narrow cracks. Its slim tip threads onto Bonstone 450ml dual cartridges, so the mixed adhesive lands precisely where the crack runs instead of pooling on the surface. The added length matters most on tight horizontal fissures where a short mixing tip simply cannot reach the base of the void.

Where the Bonstone long nozzle is used

• Injecting Bonstone Crack Repair 28 and Crack Repair 31 into thin horizontal cracks
• Filling tight fissures in granite, marble, and engineered stone
• Reaching recessed joints on countertop and slab repairs where a short tip falls short
• Pairing with Touchstone Express II Flowing 450ml cartridges

How the Bonstone long nozzle performs

• Slim bore places flowable epoxy at the base of the crack for full-depth fill
• Single-use design avoids cured residue contaminating the next pour
• Standard fit on Bonstone 450ml cartridge systems
• Runs with a manual dual-cartridge gun for steady, controlled flow
• Tapered tip starts narrow to enter hairline cracks, then feeds resin without back-pressure

Stone and countertop repair lives or dies on getting flowable epoxy all the way to the bottom of a crack, not just bridging the surface. A short tip leaves a void underneath that fails the first time the slab flexes or takes a thermal cycle. The longer reach solves that on horizontal cracks in granite, marble, quartz, and other engineered surfaces. Buy these slim tips in quantity, since each one sets up with the epoxy and is replaced for the next cartridge. Keep spares on hand to match your cartridge count and avoid downtime mid-repair.
