Fisnar Nib Polyester Chisel

The Fisnar 381-8425-PC is a polyester chisel-style replacement nib designed for use with Fisnar Flow-Seal pens such as FV-0100, FV-0200, and FV-0300. The chisel tip delivers broad, even fluid application - ideal for surface coating, edge marking, and smooth bead dispensing in precision work environments. Applications: This polyester chisel nib is ideal for tasks requiring smooth, wide-area fluid distribution: *Electronics - Applying flux, conformal coatings, and adhesives across PCB surfaces. *Manufacturing and assembly - Dispensing primers, greases, or sealants with controlled width. *Laboratory and R&D - Distributing solvents, cleaning agents, or reagents evenly on test surfaces. *General fluid dispensing - Suitable for wide-bead application in marking, coating, or bonding tasks. Usage Guidelines: *Install by securely inserting the nib into the pen valve after removing the old one. *Fill the pen reservoir with a 19 mm air gap to support spring-activated priming. *Prime by pressing the nib tip vertically onto a surface until fluid flows evenly. *Replace the nib as needed if dispensing becomes irregular or the tip shows signs of wear.
