SW-908 Polyurethane Foam Tip Applicator with Break-off Point

Product Overview

The SW-908 is a polyurethane foam tip applicator with a high-quality open-cell foam head on a long polypropylene handle incorporating an integrated break-off point, designed as a dual-configuration cleaning and application tool that can be used at its full 150mm length for extended-reach tasks or snapped to a shorter compact format at the 30mm break point for close-range bench work and portable maintenance kits — without requiring a separate tool for handle modification. The break-off point is a pre-scored notch in the handle shaft at 30mm from the base, engineered to produce a clean, controlled fracture when the operator applies lateral bending force, shortening the handle to 120mm while maintaining the handle's structural integrity and grip profile above the break point. This eliminates the contamination and irregular geometry that cutting or breaking an unscored handle produces, and allows the SW-908 to serve both field maintenance (compact format) and equipment interior cleaning (full 150mm reach) requirements from a single product SKU.

The foam head measures 21.5mm in length, 10mm in width, and 7.5mm in thickness — the largest foam head volume in this product series. The 7.5mm foam thickness provides substantial liquid absorption and retention capacity, suited to tasks requiring the swab to carry and deposit a meaningful volume of solvent, adhesive, paint, or cleaning agent in a single application pass. The open-cell foam structure allows rapid uptake of both water-based and solvent-based liquids and releases them evenly during surface contact, supporting precise application without pooling or over-saturation of localized areas.

Break-Off Point Design & Individual Packaging

The break-off point at 30mm addresses a practical constraint in portable and field maintenance contexts: many carrying cases, tool rolls, and equipment service kits have compartment lengths optimized for 100–120mm tools, and a full 150mm handle does not fit without protruding or folding. By snapping the handle at the pre-scored notch before use, the SW-908 becomes a 120mm tool that fits standard kit storage formats without sacrificing the foam head's functionality. The snap action produces a clean break with no sharp edges or splinter fragments, maintaining the hygiene of the swab and the safety of the operator's hands during the shortening step.

Each SW-908 is individually packaged in its own sealed package — the same single-piece packaging format as the lens microfiber swabs in this line — ensuring that the foam head arrives at the point of use in a clean, uncontaminated state regardless of storage duration. The polypropylene handle maintains consistent 4mm width and thickness across its full length, providing uniform grip from base to break point. Total length: 150mm. Individually packaged, 1 piece per pack.

Industry Applications & Use Scenarios

The SW-908 is used in electronics cleaning and repair, precision model building and hobby crafts, laboratory instrument maintenance, cosmetic application, and medical equipment servicing where both precise liquid application to small target areas and occasional extended-reach access to enclosed spaces are required from a single swab format. Specific use scenarios include applying adhesive, paint, or solvent to model building assemblies where a large foam head delivers more controlled coverage than a brush tip, cleaning keyboard key gaps and headphone driver housings in consumer electronics repair, applying correction fluid or touch-up paint to precision instrument panels, wiping medical equipment housing surfaces during maintenance, laboratory surface preparation involving controlled solvent application to defined zones, and cosmetic product application tasks requiring a soft foam contact surface. The break-off point makes it a practical inclusion in portable electronics repair kits and field service equipment cases where fixed-length tools are a storage constraint.
