Nalge Nunc 870 PFA Tubing, NALGENE 8051-0125 Review

Let’s Dive into Nalge Nunc 870 PFA Tubing, NALGENE 8051-0125

In the demanding world of tactical and outdoor gear, sometimes the most crucial components are the ones we take for granted. Enter the Nalge Nunc 870 PFA Tubing, NALGENE 8051-0125 from Nalgene, a seemingly unassuming piece of equipment that plays a vital role in numerous applications, from fluid transfer in harsh environments to critical lab setups. This isn’t your average hardware store tubing; it’s a meticulously engineered piece of fluoropolymer designed for resilience, purity, and uncompromising performance across a wide temperature spectrum.

My journey to discovering the Nalge Nunc 870 PFA Tubing stemmed from a pressing need for a reliable, chemically inert solution for a portable water purification system I was developing for extended backcountry expeditions. Standard tubing materials failed to withstand the rigors of constant flexing, extreme temperatures, and exposure to aggressive purification chemicals. The promise of Nalgene’s PFA tubing – its broad chemical resistance and temperature range – was exactly what I needed.

Upon receiving the 25-foot coil, my first impression was one of understated quality. The tubing’s translucent appearance hinted at its purity, and its semi-rigid nature felt substantial yet flexible. Compared to the readily available silicone and PVC tubing I had experimented with, the Nalge Nunc 870 felt a class apart – designed for a job, not just a purpose.

While other options like PTFE (Teflon) tubing offered similar chemical resistance, the Nalgene PFA boasted superior flexibility and clarity, critical for monitoring fluid flow in my application. I was excited to put it through its paces, hopeful that it would live up to its impressive specifications.

Real-World Testing: Putting Nalge Nunc 870 PFA Tubing, NALGENE 8051-0125 to the Test

First Use Experience

The initial trial involved integrating the Nalge Nunc 870 PFA Tubing into my portable water purification setup during a week-long backpacking trip in the Cascade Mountains. I needed to ensure a reliable connection between the water source, filter, and storage container. The tubing had to endure stream submersion, direct sunlight, and nighttime temperatures near freezing.

The tubing performed flawlessly under these varied conditions. It remained flexible even in the cold, and exhibited no signs of degradation or leaching after repeated exposure to iodine-based purification tablets. I also appreciated the tubing’s transparency, allowing me to easily monitor water flow and spot any potential blockages. No issues surfaced during the initial week, setting a positive tone for the long-term assessment.

Extended Use & Reliability

After several months of regular use across diverse environments, the Nalge Nunc 870 PFA Tubing continues to impress. Despite repeated flexing, compression fitting installations, and exposure to both high-altitude UV radiation and acidic stream water, the tubing shows minimal signs of wear and tear. Cleaning is a breeze; a simple flush with clean water removes any sediment or residue.

Compared to previous experiences with other tubing materials, the Nalge Nunc 870‘s durability is remarkable. Silicone tubing became brittle and cracked, while PVC degraded and leached plasticizers over time. The Nalgene tubing maintains its integrity and flexibility, proving to be a worthwhile investment for demanding applications where reliability is paramount.

Breaking Down the Features of Nalge Nunc 870 PFA Tubing, NALGENE 8051-0125

Specifications

The Nalge Nunc 870 PFA Tubing, NALGENE 8051-0125 features a ¹/₁₆ inch inner diameter (I.D.) and a ¹/₈ inch outer diameter (O.D.), resulting in a ¹/₃₂ inch wall thickness. This specific size makes it ideal for low-flow applications and use with smaller compression fittings. The tubing is constructed from high-purity Perfluoroalkoxy (PFA) resin, ensuring exceptional chemical resistance and a wide operating temperature range.

• The maximum pressure rating is 478 psig at 23°C (73°F) and 239 psig at 85°C (185°F), highlighting its ability to withstand moderate pressure levels within its specified temperature range.
• The material’s durometer hardness is Shore D, 55, indicating a semi-rigid yet flexible consistency.
• It resists water absorption and can be sterilized using autoclaving, gas, dry heat, and disinfectants, but cannot be sterilized by radiation.
• This adheres to USDA regulations for safe use.

These specifications are critical because they dictate the tubing’s suitability for specific applications. The chemical resistance ensures compatibility with a broad range of fluids, while the temperature range enables use in extreme environments. The pressure rating dictates the tubing’s ability to withstand system pressures without failing, and the sterilizability makes it ideal for sanitary applications.

Performance & Functionality

The Nalge Nunc 870 PFA Tubing excels in applications requiring chemical inertness, high-temperature resistance, and low-pressure fluid transfer. The smooth inner surface minimizes friction and ensures consistent flow rates. Its translucent nature allows for easy visual inspection of fluids, and it does its job exceedingly well.

However, its small diameter limits its use to low-flow applications, and the semi-rigid nature makes it less flexible than silicone tubing. Nevertheless, the Nalge Nunc 870 PFA Tubing exceeds expectations in terms of chemical resistance and temperature performance.

Design & Ergonomics

The Nalge Nunc 870 PFA Tubing is designed for functionality rather than aesthetic appeal. The translucent PFA material allows for easy visual inspection of fluid flow, which is very helpful. Its semi-rigid nature provides a good balance between flexibility and structural integrity.

There’s virtually no learning curve to using the tubing, as it integrates seamlessly with standard compression fittings and other fluid handling components.

Durability & Maintenance

Given the high-quality PFA material, the Nalge Nunc 870 PFA Tubing should last for many years under normal operating conditions. PFA is known for its resistance to degradation from chemicals, UV radiation, and temperature extremes, so this is a high-quality product. Cleaning is straightforward; simply flush with an appropriate solvent or detergent, depending on the fluid it carried.

Accessories and Customization Options

The Nalge Nunc 870 PFA Tubing doesn’t come with any specific accessories. However, it is compatible with a wide range of standard compression fittings and connectors from various manufacturers.
