Fine rubber tubing

Fine rubber tubing

The precise sizing of tubes is required for the application to meet the requirements. Tubing nominal sizes are determined by an exterior diameter that encompasses the whole cross-section of the tube. The inner diameter can then be used to determine the thickness of tube walls and the flow area (where appropriate) of the fluid flow inside the tube wall.

Fine rubber tubing is designed for use in the medical industry and is available in extremely small diameters. As with any product used in patient care, it must meet FDA sterility and material criteria. It is a high-gloss, inert, and sterile material used to implant veins and arteries on intravenous lines with a sturdy wall design that allows liquid fluids like blood or medications to flow freely. Fine Medical tubing complies with the USP Class VI medical application criteria for biocompatibility.

Factory-made from high-tear-resistance, peristaltic silicone-elastomer grades with consistent wall thickness and +/-0,0 5mm precision tolerances, they’re perfect for Dosing and Dispensing Systems, Automated Analytical Chemistry, and Peristaltic Pumps. Fishing tubes, robotic tubing, and fine cable electronic insulation are all examples of fine rubber tubing usage. Pump tubing for peristaltic pumps is also available. 

Apart from this, you can also avail of equipment in a variety of standard and custom sizes. Fine rubber tubing that is strong enough for easy handling yet flexible enough to prevent penetration. Micro diameters are suited for minimally invasive infusion in intravenous or intra-arterial applications. The fine silicone tube produced for acceptable tolerances is most commonly used as a fine slave. 

As far as medium-scale applications are concerned, the food manufacturing and pharmaceutical sectors are the most significant consumers. However, you will notice that no plasticizers or other toxic chemicals are added that might result in any harmful issues. It’s very tearproof and flexible (ideal for transporting fluids).

Discuss Your Requirements

Product specifications

Product form
Hollow elastomer tubing for a fitted line or sleeve
Material options discussed
Silicone. Choose one formulation for the actual contact and loading conditions.
Application focus
Medical-device assemblies, peristaltic pumping, cable sleeving, food-processing equipment and industrial fluid lines. Size the part against the selected assembly.
Dimensions to confirm
Inside diameter, outside diameter, wall thickness and cut length. Match these to medical-device assemblies and peristaltic pumping.
Small-bore control
Set bore and wall tolerances, check lumen continuity and choose fittings that do not close or distort the passage.
Contact conditions
Blood or sample fluids, medicinal contents and food ingredients: define concentration, temperature and contact time, then check compatibility with the chosen compound.
Pump-head compatibility
The described uses include peristaltic pumping. Match bore and wall to the pump head and check recovery over the required number of cycles.
Line layout
Check bend radius, unsupported spans and clearance at both connections.
