Nalge Nunc 890 Teflon FEP Tubing, NALGENE 8050-0187 Review

Let’s Dive into Nalge Nunc 890 Teflon FEP Tubing, NALGENE 8050-0187

The Nalge Nunc 890 Teflon FEP Tubing, NALGENE 8050-0187 isn’t your average piece of kit; it’s a specialized component designed for critical fluid transfer applications where purity and reliability are paramount. Manufactured by Nalge Nunc International (NNI), a name synonymous with quality labware, this tubing promises a consistent, non-contaminating lining thanks to its Teflon FEP (Fluorinated Ethylene Propylene) construction. This makes it ideal for demanding scenarios in research, industrial, and even certain outdoor applications.

My interest in this tubing stemmed from a particularly challenging project: designing a portable water purification system for extended backcountry expeditions. Standard tubing materials often leach chemicals or degrade over time, compromising water quality, a risk I wasn’t willing to take. The Nalge Nunc 890 Teflon FEP Tubing’s advertised chemical resistance and non-contaminating properties seemed like the perfect solution.

Upon receiving the tubing, the first thing I noticed was its flexibility, despite the seemingly rigid nature of Teflon. The translucent FEP material exhibited a smooth, clean surface, instilling confidence in its non-reactive nature. Its dimensions—¹/₈ inch ID x ³/₁₆ inch OD—appeared precise, promising a tight fit with standard fittings.

Compared to readily available PVC or silicone tubing, the Nalge Nunc 890 is in a different league altogether. While those materials are adequate for basic applications, they lack the chemical inertness and temperature range of FEP. This tubing stood out due to its promise of maintaining fluid integrity across a wide range of conditions.

My initial impression was one of cautious optimism, tempered by the high price tag. Would the Nalge Nunc 890 Teflon FEP Tubing truly justify its cost in real-world performance, or was I simply paying for a brand name? Only rigorous testing would tell.

Real-World Testing: Putting Nalge Nunc 890 Teflon FEP Tubing, NALGENE 8050-0187 to the Test

First Use Experience

The first test for the Nalge Nunc 890 Teflon FEP Tubing involved integrating it into my prototype water purification system during a week-long backpacking trip in the High Sierra Nevada. This environment presented a multitude of challenges: fluctuating temperatures, exposure to UV radiation, and the potential for contact with various water sources, including streams with high mineral content. The tubing served as the critical link between the water source, the filter, and the collection reservoir.

The tubing performed flawlessly throughout the trip. I observed no discoloration, deformation, or any other sign of degradation, even after prolonged exposure to direct sunlight and near-freezing temperatures. The water flowing through the system remained consistently clear and odorless, validating the tubing’s non-contaminating properties. Its flexibility made routing the tubing around obstacles in the pack relatively easy.

There were no immediate issues or surprises. The tubing connected securely to the fittings, and the system operated without leaks or interruptions.

Extended Use & Reliability

After several months of continuous use and multiple backpacking trips, the Nalge Nunc 890 Teflon FEP Tubing continues to perform admirably. There are no visible signs of wear or tear, and the tubing retains its original flexibility and transparency. The interior surface remains smooth and clean, preventing the buildup of biofilms or other contaminants.

Cleaning is remarkably simple; a quick flush with clean water is usually sufficient to remove any residual sediment. Its chemical resistance allows for using stronger cleaning agents if necessary, without fear of damaging the tubing. This is a major advantage over silicone tubing, which can be more susceptible to staining and degradation.

Compared to my previous experiences with standard PVC tubing, the Nalge Nunc 890 is a clear winner. The PVC tubing would become brittle and discolored over time, eventually requiring replacement. The FEP tubing, on the other hand, exhibits exceptional durability and longevity. It far outperforms any other tubing I’ve used in similar applications.

Breaking Down the Features of Nalge Nunc 890 Teflon FEP Tubing, NALGENE 8050-0187

Specifications

The Nalge Nunc 890 Teflon FEP Tubing, NALGENE 8050-0187 features the following specifications:

• Material: Teflon FEP (Fluorinated Ethylene Propylene), offering exceptional chemical resistance and a non-contaminating surface. This ensures fluid purity and prevents leaching of harmful substances.
• Inner Diameter (I.D.): ¹/₈ inch. This dimension dictates the flow rate and compatibility with specific fittings.
• Outer Diameter (O.D.): ³/₁₆ inch. This determines the tubing’s overall size and the type of connectors required.
• Wall Thickness: ¹/₃₂ inch. A thinner wall provides greater flexibility, but it can also reduce pressure resistance.
• Maximum Pressure @ 23°C (73°F): 250 psig. This specification indicates the maximum pressure the tubing can withstand at room temperature without rupturing.
• Maximum Pressure @ 85°C (185°F): 125 psig. Pressure resistance decreases at higher temperatures, so this is an important consideration for hot fluid applications.
• NNI No.: 8050-0187. This is the unique product identifier for ordering and identification purposes.

These specifications are critical for ensuring the tubing’s suitability for specific applications. The chemical resistance of FEP, for example, makes it ideal for handling corrosive fluids that would degrade other materials. The pressure rating ensures safe operation within specified temperature ranges.

Performance & Functionality

The Nalge Nunc 890 Teflon FEP Tubing excels in its primary function: providing a reliable and contamination-free conduit for fluid transfer. Its smooth inner surface minimizes friction, allowing for efficient flow rates. The FEP material exhibits virtually no chemical reactivity, ensuring that the fluid remains pure and unaltered.

A significant strength lies in its broad temperature tolerance, making it suitable for both hot and cold fluid applications. One area that could be improved upon would be offering a wider range of sizes to fit a broader range of projects. Overall, it meets and exceeds expectations for a high-quality, specialized tubing product.

Design & Ergonomics

The Nalge Nunc 890 features a simple, yet effective design. The translucent FEP material allows for easy visual inspection of the fluid flowing through the tubing. Its flexibility, despite the inherent stiffness of Teflon, facilitates easy routing and connection to fittings.

There is virtually no learning curve associated with using this tubing. Its ease of use and direct compatibility with standard fittings make it a user-friendly choice.

Durability & Maintenance
