Lisle Oriflo Flow-Thru Parts Washer Brush 89530 with 28" Buna N Tube — Solvent-Ready, Stiff Trialoy Bristles

The Lisle 89530 Oriflo Flow Thru Brush is a solvent-ready parts-washer brush with a continuous flow-through bristle and an included 28" Buna N tube for durable, targeted cleaning.

Built for industrial parts washers that circulate solvent, the 89530 Oriflo Flow Thru Brush channels cleaning fluid through the center of the bristle cluster so solvent reaches crevices while you scrub. Its injection-molded handle and stiff Trialoy® polyester filaments withstand repeated use in both solvent- and water-based cleaning solutions, and the supplied Buna N (nitrile) tube resists many solvent chemistries to keep the connection dependable.

How does the flow‑thru design improve parts washer cleaning?

The flow‑thru design delivers a continuous stream of solvent directly into the brushing area, flushing away loosening soils as you agitate surfaces. This combined action—mechanical scrubbing plus active solvent flow—helps dislodge trapped grime faster than dry brushing alone.

• Solvent flows through bristle core to reach tight gaps.
• Continuous flushing reduces redepositing of debris.
• Works with circulating pump systems for steady solvent supply.

What features make the 89530 durable for industrial use?

Durability comes from the brush's materials and construction: a rugged, ribbed injection‑molded handle resists impact and gives a secure grip, while Trialoy® polyester bristles stay stiff and resist breakdown in harsh cleaning solutions. The bullet-shaped tip is specifically designed to resist mushrooming so the head keeps its shape after repeated contact.

• Injection-molded handle with ribs for non-slip control.
• Stiff Trialoy polyester filament for long life in solvents and water.
• Bullet-shaped tip prevents bristle splaying (mushrooming).

Is the included 28" Buna N tube compatible with common solvents?

The 89530 ships with a 28" Buna N (nitrile rubber) tube chosen for its broad compatibility with many solvent-based cleaning solutions. Buna N offers good resistance to oils and many industrial solvents, helping maintain a leak-free connection between pump and brush in standard parts-washer service.

• 28" length provides reach inside basins or over fixtures.
• Buna N resists many solvent chemistries encountered in parts washing.
• Flexible tubing reduces kinking while remaining durable.

How easy is the brush to use and maintain?

Operation is straightforward: connect the tube to the solvent pump, hold the ribbed handle for controlled scrubbing, and let solvent flow through the bristles as you work. Maintenance is minimal—rinse after use and inspect the bullet tip and bristles; replace the brush when bristle stiffness or shape is compromised.

• Simple attach-and-go setup with circulating pumps.
• Rinseable with either solvent or water-based solutions.
• Replace when bristles soften or tip mushrooms despite design.

Who is this for: technicians and maintenance pros who operate solvent-circulating parts washers and need a robust hand brush that combines directed solvent flow with durable scrubbing action. It's ideal for automotive shops, industrial maintenance bays, and manufacturing facilities that require reliable cleaning of metal components, housings, and assemblies where trapped grime needs both agitation and solvent flushing.
