Creality Filament Dryer Pass-Through Fitting

Creality Filament Dryer Pass-Through Fitting

A simple threaded pass-through fitting designed for Creality filament dryers.
This model replaces the stock rubber grommet with a smooth low-friction filament guide for easier feeding and cleaner filament routing.

The fitting uses a threaded body with a separate locking nut for a secure installation through the dryer wall.

Works great for PLA, PETG, and other 1.75 mm filaments.

Why this model?

The stock rubber grommet in some filament dryers can create extra friction and make filament feeding less smooth.

This threaded fitting provides:

• smoother filament movement,
• cleaner routing,
• easier filament changes,
• and a more secure pass-through solution.
