Industrial oil-based marker for metal.

The uni-Paint PX-21 delivers permanent, opaque red marks on virtually any material including metal, plastic, glass and greasy parts. Its valve-action flow control prevents the tip from drying out when left uncapped, keeping the marker ready for shift work in fabrication, automotive or aviation environments. Quick-drying ink resists water, heat, fading and abrasion so identification stays legible.

Fine bullet tip limits line width to a single

The fine bullet point lays down one consistent line per pass, making it unsuitable for broad-area coverage or large-letter stencilling. Valve actuation requires a brief shake and depress cycle before first use, so instant mark-making on fast-moving lines is not practical. Ink is oil-based and permanent, therefore it cannot be erased or washed off once cured.

Red colour identifies the ink in the cap and barrel

The marker ships as a single red unit (model 63702) with colour-matched components for quick visual selection in a mixed tool crib. No other colours are included in this pack, so teams needing colour-coded inspection marks must purchase additional markers separately. Industrial-grade construction means the metal barrel and durable tip withstand daily heavy use.

Questions about this item

Should I choose the PX-21 fine bullet tip or a broader tip for detailed marking?

The PX-21 has a fine bullet tip that produces thin, precise lines, making it suitable for detailed work on metal, plastic or oily surfaces.

How does the oil-based ink perform once applied to equipment?

The red oil-based paint dries quickly and resists water, fading, heat and abrasion, leaving opaque, glossy marks on both light and dark materials.

Does the valve-action mechanism prevent the marker from drying out when left uncapped?

Yes, the valve action controls ink flow and stops the tip from drying out even if the cap is left off for a period.
