BSI BSI305 PTFE Tubing CA Applicator — Flexible Tip Extension

The BSI® BSI305 PTFE Tubing CA Applicator is a flexible tip extension for applying cyanoacrylate (CA) glue with precision in tight spaces and hard-to-reach areas. PTFE (polytetrafluoroethylene) tubing is used for CA applicator tips because CA adhesive does not bond to PTFE — the flexible tip stays clear and reusable rather than clogging and hardening like standard plastic tips. The flexible construction allows the tip to bend and reach into confined areas, joints, and seams where a rigid tip cannot access, making it ideal for RC model building, aircraft construction, woodworking, and any application requiring precise CA placement in restricted spaces.

Key Features

• Part Number: BSI305
• BSI PTFE tubing CA applicator flexible tip extension
• PTFE construction — CA adhesive does not bond to PTFE, keeping the tip clear and reusable
• Flexible tip bends to reach tight spaces, joints, and confined areas
• Compatible with BSI CA glue bottles and standard CA applicator bottles

Compatibility

• Compatible with BSI .5 oz, 1 oz, and 2 oz CA glue bottles and standard CA applicator bottles — verify tip fit with your specific bottle before use

Benefits

• PTFE construction prevents CA from bonding to the tip — stays clear and reusable longer than standard plastic tips
• Flexible tip reaches into tight spaces, joints, and seams inaccessible with rigid tips
• Enables precise CA placement for cleaner, more controlled glue application
• Reduces waste and mess from over-application in confined areas
• Essential accessory for RC model building, aircraft construction, and precision hobby work

Quick Take

Trying to get CA into a tight joint or confined seam? BSI BSI305 PTFE flexible tip bends to reach where rigid tips can’t — and CA won’t bond to PTFE, so the tip stays clear and reusable.
