Butterfly Wing Nozzle / Flange Seam Nozzle – Precision Sealer Nozzle for Automotive Bodywork

Professional sealing bead applicator for body-shops 

The Butterfly Wing Nozzle / Flange Seam Nozzle from CE Chem is a specialist applicator designed to provide accurate, consistent, trade-grade sealant beads for body-panel seams, door/bonnet edges, hem-flanges and other sealing applications. Supplied as a 10-pack and easily cut to size, it’s ideal for busy bodyshops, mobile repair technicians and SMART repair workflows. The wing-profile ensures controlled spread, reduced mess, and a clean finish.

Key Benefits

• Designed for precision bead application: the “wing” shape guides the sealant, helping to achieve consistent width and edge placement. 

• Cut-to-length design: allows technicians to customise the bead width for specific joints or panel edges.

• Compatible with standard cartridge/sealer gun systems—ensuring workflow fits body-shop equipment.

• Helps improve productivity: consistent beads, less waste, faster finishing.

• Ideal for sealing hem-flanges, door skins, bonnet edges and other areas where factory style or trade-quality sealing is required.

Typical Applications

• Sealing door and bonnet edges where panel joints meet and need a consistent bead.

• Hem-flange and hidden seam sealing in body repair or manufacturing.

• Mobile or fixed-bay bodyshops where efficient, high-quality sealing is required.

• SMART repair scenarios where a clean, accurate application reduces re-work and improves finish quality.

• Use with PU, MS-polymer or other trade sealants requiring precise nozzle control for mixed substrates (metal, aluminium, composites).

• Supplied in M15 thread for use with sealer guns.

How to Use

1. Select the nozzle and cut the wing to the desired width for your bead.

2. Attach to applicator gun according to your sealing system.

3. Ensure clean surfaces: ensure the joint or flange is free of loose material, oil, wax or contamination before applying sealant.

4. Apply sealant using the nozzle: support the wing against the edge or surface as your guide for a consistent line.

5. Finish: smooth or tool the bead if required, then allow the sealing product to cure or over-coat as per manufacturer instructions.
