What Is the King Cobra Solvent Trap?


Product Overview

A distinctive D-size aluminum cleaning system
centered around an 8.5-inch heavy-knurled tube.

During routine firearm cleaning, a solvent trap
is intended to help contain liquid cleaning solvent,
carbon residue, and dirty runoff rather than allowing
those materials to drain freely onto the work surface.

King Cobra combines that cleaning function with its
own matching tube, adapter, and solid-end component
family.

King Cobra Heavy-Knurl Construction


01

The King Cobra tube uses a pronounced exterior
knurl that distinguishes it from standard
D-size tube designs.

The textured aluminum exterior provides additional
handling surface during cleaning, inspection,
and routine maintenance.

Matching King Cobra adapters and solid-end components
are available separately or as part of selected
product configurations.
