Breaking Down the Features of Ohio Valley Chemical Stainless Steel Nut 1/4″ Each SS-402-1
Specifications
The Ohio Valley Chemical Stainless Steel Nut 1/4″ Each SS-402-1 is defined by its precise dimensions and material composition. It features a 1/4″ thread size, which is a common standard in many laboratory and industrial applications, particularly for connecting chromatographic columns or other gas lines. The primary material is stainless steel, a critical choice for its inherent resistance to corrosion, high temperatures, and chemical inertness, all vital in a gas chromatography environment.
The quantity provided is 1 each, making it ideal for replacing a single damaged or worn component without having to purchase a larger, unnecessary pack. This specific size and material ensure a secure, leak-proof connection for tubing and fittings, preventing sample contamination and maintaining system pressure stability. The SS-402-1 designation likely refers to a specific manufacturer’s internal catalog number, ensuring traceability and ease of reordering.
In comparison to nuts made from softer metals, the stainless steel composition of this component offers superior durability and resistance to galling or stripping, even with repeated tightening and loosening. This robustness is crucial for maintaining the integrity of vacuum or pressure systems in scientific instruments. The 1/4″ sizing is standard for many GC fittings, facilitating broad compatibility.
Performance & Functionality
The primary function of this nut is to provide a secure, leak-free connection within a gas chromatography system. In my experience, it performs this role exceptionally well. The threads are clean and precisely machined, allowing for smooth engagement with the corresponding fitting, and most importantly, creating an airtight seal.
Its performance in maintaining system pressure was flawless during my testing period. There were no instances of minor leaks, which can be a recurring problem with lower-quality fittings, especially under varying thermal conditions. The stainless steel material also contributes to its resistance to common laboratory chemicals and solvents, ensuring long-term performance.
This nut meets and slightly exceeds expectations for its intended application. It provides the critical sealing functionality required for accurate analytical results, demonstrating a level of reliability that surpasses many generic alternatives.
Design & Ergonomics
The design of this nut is functionally driven, prioritizing a secure and reliable connection. The stainless steel construction provides a reassuring weight and feel, suggesting durability and robustness. Its knurled exterior offers a sufficient grip for manual tightening, though a wrench is recommended for final securement to prevent over-tightening, which can damage delicate tubing.
Ergonomically, it’s a simple component designed for its specific purpose; there are no elaborate features, just a clean, functional form factor. The clear 1/4″ sizing and the evident material quality make it easy to identify and integrate into a system.
The overall build quality feels excellent, with a smooth, consistent finish across its entire surface. There are no rough edges or imperfections that could compromise the seal or make it difficult to handle. It’s a product that clearly benefits from precise manufacturing.
Durability & Maintenance
Given its stainless steel construction and straightforward design, the Ohio Valley Chemical Stainless Steel Nut 1/4″ Each SS-402-1 is built for longevity. For a component in a laboratory setting, especially within a GC system, it’s designed to be a long-term fixture. I anticipate it will last for many years, barring any extreme physical damage.
Maintenance is virtually non-existent. It’s corrosion-resistant and chemically inert, meaning it won’t degrade under normal laboratory conditions. If it were to become contaminated with a stubborn substance, a simple wipe-down with an appropriate solvent or alcohol would suffice.
There are no inherent failure points that I can identify with this type of nut, beyond the potential for cross-threading or over-tightening, which are user-induced issues. Its solid construction makes it highly resistant to mechanical failure.
Accessories and Customization Options
As a singular nut component, the Ohio Valley Chemical Stainless Steel Nut 1/4″ Each SS-402-1 does not come with additional accessories, nor does it have built-in customization options in the traditional sense.
