First Use Experience
I primarily tested these NALGENE closures in my workshop, which doubles as my gear maintenance and storage area.

The closures performed admirably under these conditions. Even with temperature swings from 40°F to 90°F, the seals remained tight, preventing any leaks or evaporation. The threads engaged smoothly and securely, providing a confident closure with minimal effort.
The ease of use was immediately apparent. There was no need for fiddling or adjusting. I simply screwed them on until snug, and they did their job.

After several months of use, the Nalge Nunc Polypropylene Screw Closures, NALGENE 712160-0384, Pack of 12, continue to perform flawlessly. There’s been no evidence of cracking, warping, or any other form of material breakdown. The threads still engage smoothly, and the seals remain airtight.
The durability of these closures is impressive. Even after repeated use and exposure to various chemicals, they show virtually no signs of wear and tear. This speaks volumes about the quality of the polypropylene used in their construction.
Maintenance is a breeze. A quick rinse with water or a mild detergent is all that’s needed to keep them clean. Their chemical resistance also prevents staining or discoloration, which helps maintain a professional appearance.
