SKU CH-S8FA-TVX7H MPN 63630

Six oil-based paint markers with medium bullet tips create permanent, opaque marks on virtually any surface

  • Product typeMarkers
  • Oil-based ink resists water, fading, heat and abrasion
  • Valve-action flow control prevents drying out when uncapped
  • Medium bullet tip gives opaque marks on light and dark surfaces
  • Six assorted colours in one set for quick colour coding
  • Industrial-grade metal barrel and durable tip extend marking life

Industrial Marking Set

The uni-ball Uni-Paint PX-20 set contains six oil-based paint markers with medium bullet tips. Assorted colours include black, blue, green, red, white and yellow. Valve action controls ink flow and prevents the tip from drying out when left uncapped. The white metal barrels are built for long marking life in industrial environments.

Quick-Dry Resistance

Permanent paint dries quickly and resists water, fading, heat and abrasion once cured. Marks stay opaque and glossy on both light and dark surfaces without bleeding. The oil-based formula adheres to oily, greasy or wet substrates where standard ink markers fail. Industrial grade construction suits manufacturing, construction and automotive use.

Sustained Marking Performance

Valve action maintains consistent flow during extended marking sessions without flooding or skipping. The durable bullet tip retains its shape on rough materials such as metal, concrete and plastic. Ink remains workable in the barrel between uses thanks to the anti-dry-out design. Suitable for part identification and equipment labelling outdoors.

Questions about this item

How do I get the ink flowing in a uni-Paint PX-20 marker, and what step prevents it from drying out?

Shake the marker with the cap on until the ball rattles, then press the bullet tip down firmly on scrap material until paint saturates the tip; always recap tightly after use because the valve-action seal stops the oil-based ink from skinning over.

What part of the uni-Paint PX-20 set will need replacement first with heavy industrial use?

The medium bullet tip will wear down on abrasive surfaces like concrete or rusted metal, and the oil-based ink reservoir cannot be refilled, so the whole marker is replaced when flow becomes inconsistent.

What limit appears first when marking continuously on hot metal with these markers?

The paint film remains heat resistant for normal industrial conditions, but sustained contact with very hot surfaces will accelerate drying at the tip and reduce opacity before the barrel or valve mechanism fails.
