K&S Precision Metals Round Stainless Steel Tube 87117
The 87117 tube from K&S Precision Metals is 5/16″ outer diameter with a 22-gauge thickness, crafted from welded 304/304L stainless steel. This combination delivers solid strength and wear resistance, suitable for demanding industrial and DIY applications. It is frequently used in medical-related tubing runs, hydraulic lines, and other assemblies where corrosion resistance and durability matter. The welded construction helps maintain dimensional stability under pumping, pressure, or thermal cycling, which can be beneficial for devices and fixtures encountered in clinical environments. The tube supports reliable performance in environments exposed to fuels, high temperatures, and general wear.
Key features include rust resistance from the 304/304L alloy, reliable mechanical strength, and versatility across automotive, plumbing, and medical contexts. The 12″ length is convenient for short to mid-length runs, enabling straightforward integration into compact assemblies or experimental setups. For projects requiring precise fit and repeatable performance, this tube offers a well-balanced option between strength and formability.
K&S Precision Metals Round Stainless Steel Tube 87119
The 87119 model is a 3/8″ OD tube with 22-gauge thickness, also produced from 304/304L stainless steel. It shares the same welded construction and durability benefits as the 87117, making it suitable for more substantial tubing runs in medical device assemblies, hydraulic lines, or sophisticated lab setups. The larger diameter accommodates higher flow requirements or tighter routing where space allows. Its corrosion resistance helps maintain cleanliness and integrity in medical-processing environments and outside applications subjected to heat and fuel exposure. This tube balances practicality with robust performance for critical systems.
In medical or clinical settings, 87119 can support instrumentation feeds, gas supply lines, and water-management components where dependable mechanical properties are essential. Like other 304/304L stainless products, cleaning and sterilization processes should be considered to preserve surface integrity and minimize contamination risk in sensitive environments.
GEPPHILL 304 Stainless Steel Coil Tubing
GEPPHILL offers a 1/2″ OD stainless steel coil tubing, 25 feet in length, with 304-grade stainless and ASTM A269 alignment. This high-grade coil is designed for high-temperature applications and fluid transfer in industrial machinery, food-processing contexts, and medical equipment that requires dependable corrosion resistance and cleanability. The continuous coil facilitates long, uninterrupted runs with fewer joins, which can reduce leak points and streamline sterilization workflows in controlled environments.
The coil’s precision engineering supports smooth bending, thanks to its annealed temper, making it suitable for custom plumbing, automotive coolant lines, and compressed air systems. The mirror-polished surface reduces particulation and buildup, which is beneficial in equipment where hygiene and ease of cleaning are priorities. Users should verify compatibility with autoclave or sterilization processes and ensure that endotoxin control measures align with intended medical applications.
MOKOVI 2 Pcs 1/4″ Stainless Steel Tubes
These two 16″ tubes measure 1/4″ OD with a robust 1mm wall thickness, composed of 304 stainless steel and noted for high corrosion resistance and weldability. They are suitable for small-scale medical fabrication, instrumentation lines, or lab hardware requiring reliable stainless steel tubing. The larger wall thickness supports better mechanical strength under bending or forming while maintaining a manageable diameter for compact assemblies. Proper threading or welding tools are required to integrate these pieces into systems.
Applications span lightweight medical device housings, prototype rigs, and small-diameter fluid or gas transport paths. When deploying these tubes in clinical or research settings, consistent surface quality and cleanliness are essential for sanitary handling. They provide a practical option for projects demanding stable dimensions and dependable performance in moderate-temperature environments.
uxcell 304 Stainless Steel Tube Pack
The uxcell pack includes multiple small-diameter tubes across several OD options (1mm to 6mm) in 300 mm lengths, all made from 304 stainless steel. This package targets experimentation, prototyping, or educational setups where a range of tube sizes is beneficial. The set’s polished finish provides a clean, smooth surface that supports easy sterilization and reduces surface roughness where fluids pass or samples are handled. The broad diameter range makes it a versatile starter kit for lab benches or maker spaces focused on medical device prototyping and microfluidics.
Buying Guide: Key Purchase Considerations And Comparisons
When choosing medical-grade stainless steel tubing, consider these factors to ensure the best fit for your project:
- Material grade: 304/304L offers good corrosion resistance and cleanliness; verify if higher grades (e.g., 316L) are needed for saline or harsher chemical exposure.
- Diameter and wall thickness: Larger diameters support higher flow; thicker walls increase strength but reduce flexibility. For sterilizable medical applications, ensure compatibility with cleaning and sterilization methods.
- Manufacturing method: Welded vs seamless affects integrity under pressure and bend radius. For high-pressure or critical fluid paths, seamless alternatives may be preferred.
- Coating and surface finish: Mirror-polished finishes resist buildup and ease cleaning. Finish quality matters for hygienic handling and sterilization cycles.
- Length and flexibility: Coil tubing enables long, uninterrupted runs; shorter straight tubes suit compact devices. Plan for bending radii to avoid kinking.
- Cleanliness and certifications: Look for medical-grade certifications, cleanroom compatibility, and traceability to ensure compliance with regulatory standards.
- Cost and availability: Compare unit costs, lead times, and supplier support, especially for parts used in critical medical devices or lab instruments.
In practice, select a mix of standard sizes to match anticipated system interfaces, while retaining flexibility for future iterations. For medical applications, emphasize cleanability, surface finish, and consistent quality across batches to minimize contamination risk and maintain reliable performance.
