Fisnar Acrylic Bullet Nib

The Fisnar 381-8425-AB is an acrylic bullet-style replacement nib designed for Fisnar Flow-Seal pens. It is commonly used with 10 ml dispensers like the FV-0100 and FPA-10 spring-loaded pens. The bullet tip shape enables controlled bead dispensing without scratching or piercing surfaces, making it ideal for precision fluid application.

Key Features:
*Acrylic construction offers chemical compatibility with a variety of low-viscosity fluids, including fluxes, solvents, inks, and lubricants.
*Bullet tip design provides smooth, controlled fluid release, ideal for bead or spot applications.
*Flow-seal compatible, specifically engineered for use in Fisnar flow-seal pens, preventing evaporation, splatter, and flooding.
*OEM-grade replacement nib, ensuring reliable fit and consistent performance with Fisnar systems.

Applications:
The Fisnar 381-8425-AB bullet nib is suitable for a range of industries and fluid types:
*Electronics: Precise dispensing of solder flux, adhesives, or conformal coatings onto PCBs and components.
*Laboratory and R&D: Controlled dosing of chemicals, reagents, inks, and lubricants in testing or sample preparation.
*Light manufacturing: Accurate application of adhesives, inks, lubricants, and marking fluids in assembly or prototyping.
*General dispensing: Suitable for any process requiring precise placement of low-viscosity fluids using Flow-Seal pens.

Usage Guidelines:
*Installation: Remove the existing nib and securely insert the new 381-8425-AB into the pen body.
*Filling: Leave an air gap (approximately 19 mm from the top of the reservoir) to allow proper air priming.
*Priming: Press the pen vertically against a surface until fluid begins to flow evenly.
*Replacement: Swap out the nib when reduced flow, wear, or clogging occurs for optimal performance.
