Let’s Dive into Nalge Nunc 870 PFA Tubing, NALGENE 8051-0187
The Nalge Nunc 870 PFA Tubing, NALGENE 8051-0187, manufactured by Nalge Nunc International, is a seemingly unassuming piece of lab equipment that promises a critical function: reliable fluid transfer and mixing in demanding environments. This isn’t your garden-variety plastic tubing; it’s constructed from Perfluoroalkoxy (PFA), a fluoropolymer lauded for its exceptional chemical resistance and thermal stability. The Nalge Nunc 870 PFA Tubing, NALGENE 8051-0187 aims to be the go-to solution for situations where contamination is unacceptable, or extreme conditions render other materials useless.
My journey to this product began with a particularly frustrating experience in the field. I needed to create a portable water purification system for extended backcountry trips, one that could handle even the most questionable water sources. The problem was finding tubing that wouldn’t leach chemicals into the purified water, withstand extreme temperatures, and maintain its integrity under pressure.
Upon receiving the Nalge Nunc 870 PFA Tubing, NALGENE 8051-0187, I was immediately impressed by its smooth, almost glass-like appearance and noticeable flexibility. Compared to standard PVC or silicone tubing, the PFA material felt significantly more robust and chemically inert. It had a reassuring heft to it, suggesting high-quality construction.
I considered several alternatives, including PTFE (Teflon) tubing and specialized silicone options designed for food-grade applications. I chose the Nalge Nunc 870 PFA Tubing, NALGENE 8051-0187 for its superior chemical resistance profile, particularly against harsh acids and solvents that might be encountered in extreme environments. The specified pressure rating also gave me confidence in its ability to handle the demands of a portable water purification system.
My initial impression was one of cautious optimism. The price tag of $769.99 is undeniably steep for tubing, but if it delivers on its promise of uncompromising performance and reliability, the investment could be worthwhile. It felt like holding a specialized tool, something engineered for a specific purpose where failure is not an option.
Real-World Testing: Putting Nalge Nunc 870 PFA Tubing, NALGENE 8051-0187 to the Test
First Use Experience
My first test of the Nalge Nunc 870 PFA Tubing, NALGENE 8051-0187 was in the rugged backcountry of the Sierra Nevada mountains. I integrated it into a gravity-fed water filtration system, sourcing water from a murky stream known for its high mineral content and occasional algal blooms. The conditions were variable, with temperatures ranging from near-freezing at night to warm and sunny during the day.
The tubing performed flawlessly. It remained flexible even in the cold temperatures, and I observed no signs of leaching or degradation after prolonged exposure to the untreated water. The smooth inner surface of the PFA also seemed to minimize flow restriction, contributing to a decent filtration rate.
One minor challenge was initially securing the tubing to barbed fittings. PFA, while flexible, can be slippery. After a little experimentation, I found that using hose clamps provided a secure and leak-proof connection.
Extended Use & Reliability
After several months of regular use on various outdoor excursions, the Nalge Nunc 870 PFA Tubing, NALGENE 8051-0187 continues to impress. There are no visible signs of wear and tear, despite being subjected to abrasion from rocks, exposure to UV radiation, and repeated flexing. The tubing remains remarkably clean, both internally and externally.
Maintenance is incredibly simple. A quick rinse with water is usually sufficient to remove any accumulated debris. I occasionally use a mild detergent solution for more thorough cleaning, but the PFA material resists staining and odor retention.
Compared to previous experiences with standard tubing materials, the Nalge Nunc 870 PFA Tubing, NALGENE 8051-0187 far outperforms them in terms of durability, chemical resistance, and overall reliability. While the initial cost is significantly higher, its longevity and peace of mind it provides make it a worthwhile investment for critical applications. It has earned its place as a core component in my backcountry kit.
