Let’s Dive into Nalge Nunc 890 Teflon FEP Tubing, NALGENE 8050-0250, Pack
The Nalge Nunc 890 Teflon FEP Tubing, NALGENE 8050-0250, Pack from Thermo Fisher Scientific (Nalgene) isn’t exactly the type of gear I’d typically review in the context of tactical or outdoor applications, yet its remarkable properties make it surprisingly relevant. This isn’t your average garden hose; we’re talking about high-performance fluorinated ethylene propylene (FEP) tubing designed for demanding laboratory environments, where purity and chemical resistance are paramount. This pack, with its 25-foot coil of translucent tubing, promises a level of inertness and temperature tolerance that I’ve often sought in creating customized hydration or fluid transfer systems for extreme conditions.
My usual go-to for hydration systems involved standard PVC or silicone tubing, but I was constantly battling issues of taste contamination and degradation when exposed to harsh chemicals or extreme temperatures. I needed something that could handle prolonged exposure to various water purification tablets, high UV radiation, and even accidental contact with solvents during maintenance. This Nalge Nunc 890 Teflon FEP Tubing stood out due to its exceptional chemical resistance and wide operating temperature range, promising a solution to my existing problems.
Upon receiving the pack, my initial impression was that of clinical precision. The tubing was neatly coiled, immaculately clean, and possessed a reassuring semi-rigidity, signaling its ability to withstand some pressure without collapsing. Compared to flexible silicone options, it felt more robust, and unlike PVC, there was no discernible plastic odor. This immediately gave me confidence in its potential for a truly pure and durable fluid transfer solution.
I considered other high-grade tubing options, like those from Cole-Parmer, but ultimately chose the Nalgene product due to its readily available specifications on chemical compatibility and temperature ratings, as well as the reputation of Nalgene for laboratory-grade reliability. The higher price point, around $450, was a hurdle, but the promise of long-term performance and zero contamination swayed my decision. I was excited to explore the potential for creating a truly bomb-proof hydration setup, but also slightly apprehensive about working with a less flexible material than I was used to.
Real-World Testing: Putting Nalge Nunc 890 Teflon FEP Tubing, NALGENE 8050-0250, Pack to the Test
First Use Experience
My first field test involved integrating the Nalge Nunc 890 Teflon FEP Tubing into my backcountry water filtration system during a week-long solo hiking trip in the high desert of Arizona. The primary goal was to assess its ability to withstand the harsh UV exposure and handle multiple water sources, including those with potentially high mineral content. The tubing connected my water bottle to a portable pump filter, and then to my hydration reservoir.
The desert environment provided a perfect proving ground, with daytime temperatures soaring above 100°F and intense solar radiation. The tubing performed flawlessly, showing no signs of degradation or discoloration. Its smooth inner surface seemed to resist the buildup of mineral deposits, and, more importantly, there was no discernible plastic taste imparted to the water, even after prolonged exposure to the sun. The semi-rigid nature of the tubing made it a little more challenging to route through my pack compared to more flexible options, but I quickly adapted.
Initially, I was concerned about the tubing’s ability to handle the constant flexing and bending as I moved, but the material proved surprisingly resilient. I experienced no leaks or kinks, and the mechanical compression fittings held securely, maintaining a watertight seal.
Extended Use & Reliability
After several months of regular use on various outdoor excursions, including a fishing trip where it inadvertently came into contact with some oil-based lures, and a survival skills course where it was subjected to both boiling water and near-freezing temperatures, the Nalge Nunc 890 Teflon FEP Tubing continues to impress. There is no visible wear and tear, cracking, or any other signs of material fatigue. Cleaning is exceptionally easy – a simple flush with clean water removes any residual debris.
The Teflon FEP material has proven to be highly resistant to staining and retains its translucent appearance, even after repeated exposure to muddy water and harsh cleaning agents. Compared to my previous silicone tubing, which often discolored and required frequent replacement, this Nalgene tubing appears to be a significant upgrade in terms of longevity and reliability. It has definitely exceeded my expectations, especially in maintaining water purity under demanding conditions.
