6" Nockennut-Staubschutzstecker | Tough-Tite | Aluminium

The aluminum body feels solid and durable, not like the plastic ones I've used before, and it clicked in firmly with a satisfying seal. Exactly what I needed to protect my female coupler from dust and debris when it's not in use.

Slid right into the coupler with a satisfying click, and the aluminum feels solid enough to survive years of shop abuse. The sealing face sits flush, so I’m confident dust and grit won’t sneak in while this is disconnected. Exactly what I needed for capping my lines between jobs.

The machining on this aluminum plug is clean and precise, so it seats into the coupler without any wobble. It's a solid little piece that does exactly what it should to keep dust out of my disconnected lines.
