Unique-Bargains DB-25 Parallel Port Dust Cap Black 5pcs

SKU CH-GP6Z-ZN0Q2

Five silicone caps protect DB-25 parallel ports from dust and debris when not in use

  • Protects DB-25 parallel ports from dust and debris using silicone caps
  • Five black covers included so spares are always on hand
  • Flexible silicone material resists wear while sealing out oxygen
  • Compact 40 x 11 x 6 mm size fits standard 25-pin ports snugly
  • Simple push-in installation keeps unused ports clean without tools

DB-25 Parallel Port Protection

These five silicone caps shield unused DB-25 parallel printer ports from dust and debris. They suit offices and retail environments that still operate legacy POS equipment with 25-pin interfaces. The black silicone material resists environmental contaminants while the pack quantity covers multiple workstations or spare inventory.

Friction-Fit Installation

Each cap presses into a 38 x 8 mm port opening without tools or fasteners. The 40 x 11 x 6 mm overall dimensions allow the cover to sit flush against the panel, leaving adjacent connectors accessible. No cables, adapters or software configuration are required; the caps simply occupy the port when the printer cable is disconnected.

Long-Term Port Integrity

The silicone construction retains flexibility across temperature cycles, so the seal remains effective after repeated insertion and removal. By blocking oxygen and particulate ingress, the caps reduce contact oxidation that can cause intermittent communication on legacy parallel links. They address the ongoing maintenance need of equipment that cannot be upgraded to modern interfaces.

Questions about this item

What is the inside install size that limits how far the cap seats on a DB-25 port?

The inside install size is 38 by 8 millimetres (1.5 by 0.31 inches), which determines how deeply the silicone stopper seats on a 25-pin DB-25 parallel printer port.

Does the silicone material soften or become tacky when the port area warms up during all-day operation?

The caps are made from environment-friendly silicone that remains stable at typical equipment temperatures, so they do not soften, melt or turn tacky during continuous use.

Which specific port type must the equipment already have for these caps to fit?

The caps fit a 25-pin DB-25 parallel printer port (LPT); they will not fit serial, VGA, SCSI or other D-sub connectors.
