First Use Experience
I first tested the Qorpak Black Phenolic Screw Caps in my workshop, focusing on their ability to seal various liquids commonly used in outdoor and tactical gear maintenance.

The ease of use was immediately apparent; the caps threaded smoothly and the Poly-Seal Liner provided a snug fit with minimal effort. Initially, I noticed that the feel of these caps instilled confidence.
