VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length Review

Let’s Dive into VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length

The VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length might not sound exciting, but in the world of precision instruments and controlled environments, reliable vacuum tubing is absolutely critical. Manufactured by VWR, this tubing promises to be a dependable link in the chain for maintaining vacuum integrity. It boasts a heavy wall construction, making it suitable for demanding vacuum applications.

My journey to discover the VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length started with a frustrating problem. I was tasked with setting up a custom vacuum sealing system for preserving sensitive electronics in a controlled atmosphere. The existing tubing I had kept collapsing under vacuum, rendering the whole setup useless. I needed something robust and reliable, capable of maintaining a tight seal consistently.

Upon unboxing the VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length, my initial impression was positive. The black rubber felt dense and substantial, with a smooth, uniform finish. The coil was neatly wound, and the tubing felt flexible enough to work with, yet rigid enough to hold its shape.

Compared to standard hardware store tubing, like the clear vinyl stuff, the VWR tubing felt like a significant upgrade. I’d also looked at silicone tubing, but the price point of the VWR was much more appealing. The silicone was also less resistant to tearing in my experience.

Initially, I was cautiously optimistic. I had high hopes for this tubing to solve my vacuum sealing woes.

Real-World Testing: Putting VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length to the Test

First Use Experience

My first test involved connecting the VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length to a vacuum pump and a custom-built vacuum chamber. This was done in my workshop, which is usually a relatively clean and dry environment. I observed the tubing under increasing vacuum pressure.

The tubing performed admirably, maintaining its shape and seal even at high vacuum levels. There were no signs of collapse or leakage. It was significantly easier to work with compared to the flimsy tubing I had been using previously.

I was initially surprised at how easily it formed a tight seal around the fittings without any additional clamps (though clamps are always a good idea for long-term reliability). This saved me some time and hassle during the setup.

Extended Use & Reliability

After several weeks of continuous use, the VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length has proven to be remarkably durable. It shows no signs of cracking or deformation. Even with repeated flexing, the rubber maintains its integrity.

Cleaning is straightforward. A simple wipe down with a damp cloth removes any surface dust or grime. No special cleaning agents are required.

Compared to my past experiences with cheaper tubing, the VWR tubing is a clear winner. It consistently outperforms its predecessors in terms of vacuum integrity and durability. The consistent performance is what sets it apart.

Breaking Down the Features of VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length

Specifications

• The VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length has an I.D. of 1/4 inch and an O.D. of 3/4 inch. This is a common size for many laboratory and industrial vacuum applications.
• The wall thickness is 1/4 inch, which is particularly heavy, designed for vacuum resistance. The thicker wall is vital for preventing collapse under vacuum.
• The tubing is made from good-quality natural rubber. This material provides excellent flexibility and sealing properties.
• The tubing comes in a 50-inch coil length. This provides sufficient material for multiple connections or longer runs.
• The durometer hardness is Shore A, 50. This indicates a good balance of flexibility and rigidity.
• The tensile strength is rated at 2500-3500psi. This provides high resilience, good tensile strength, and tear resistance.

These specifications are important because they directly impact the tubing’s ability to maintain a reliable vacuum seal under varying conditions. The thick wall and high tensile strength ensure that the tubing can withstand the stresses of vacuum applications without collapsing or tearing.

Performance & Functionality

The VWR Black Vacuum Rubber Tubing 9764 50″ Coil Length excels at its primary function: maintaining a reliable vacuum seal. It exhibits excellent resistance to collapse under vacuum. The natural rubber material provides a good seal with fittings.

Its strength lies in its robust construction and consistent performance. A potential area for improvement might be to offer the tubing with a smoother inner surface to reduce friction and improve flow.

The product certainly meets and exceeds expectations. Especially considering the critical nature of vacuum seals in certain applications.

Design & Ergonomics

The tubing is constructed from high-quality natural rubber. This material offers a good balance of flexibility and durability. Its black color helps to minimize light penetration, which can be important for light-sensitive applications.

The tubing is generally user-friendly. No special tools are required for cutting or connecting it.
