Industrial-Grade 1 2 Silicone Tubing – High-Purity, Flexible, and Durable Fluid Transfer Solutions
In demanding industrial environments, the reliability of your fluid transfer systems depends on the quality of your components. Our 1 2 silicone tubing is engineered to meet the rigorous standards of the pharmaceutical, food processing, and biotech industries. This semi-transparent, platinum-cured silicone hose offers exceptional purity, temperature resistance, and mechanical flexibility. Whether you are handling sterile liquids, corrosive chemicals, or high-temperature gases, this tubing provides a safe, non-toxic, and long-lasting solution. Designed for OEMs and process engineers, it ensures consistent flow rates and minimal particle shedding, making it a trusted choice for critical applications.
Product Overview
Our 1 2 silicone tubing refers to tubing with a nominal inner diameter of 1/2 inch (12.7 mm), manufactured from high-consistency silicone rubber (HCR) via a platinum-catalyzed curing process. This method eliminates harmful by-products, resulting in a biocompatible, odorless, and tasteless product. The tubing is available in various durometers (typically 50 to 70 Shore A) and wall thicknesses to suit different pressure and vacuum requirements. It complies with USP Class VI, FDA 21 CFR 177.2600, and ISO 10993 standards, ensuring safety for direct contact with pharmaceuticals and foodstuffs.
Key Features
- Platinum-Cured Purity: No peroxides or organic volatiles, minimizing extractables and leachables.
- Wide Temperature Range: Stable performance from -60°C to +200°C (-76°F to +392°F), with intermittent steam sterilization up to +135°C.
- Excellent Flexibility: Bend radius as low as 1.5x the outer diameter, preventing kinking in tight spaces.
- Chemical Resistance: Resistant to alcohols, mild acids, alkalis, and ozone; suitable for many solvents.
- Non-Stick Surface: Low friction coefficient reduces particle adhesion and simplifies cleaning.
- Translucent Appearance: Allows visual monitoring of fluid flow and detection of air bubbles or blockages.

FAQ
Q: What is the difference between platinum-cured and peroxide-cured silicone tubing?
A: Platinum-cured silicone, like our 1 2 silicone tubing, uses a catalytic curing process that leaves no harmful residues. Peroxide-cured silicone may contain trace amounts of 2,4-dichlorobenzoyl peroxide, which can leach into fluids. Platinum-cured is preferred for pharmaceutical, food, and medical applications due to its higher purity and biocompatibility.
Q: Can this tubing be used with peristaltic pumps?
Yes, absolutely. Our tubing has excellent flexibility and fatigue resistance, making it suitable for peristaltic pump applications. For optimal pump life, we recommend a wall thickness of 1/8 inch (3.2 mm) for the 1/2-inch ID size. We can also supply tubing with a thicker wall (3/16 inch) for higher pressure applications.
Q: What is the maximum operating pressure for 1 2 silicone tubing?
At room temperature (23°C), the maximum working pressure is approximately 0.5 MPa (72 psi) for continuous use. Burst pressure is higher (>1.5 MPa). Pressure ratings decrease at elevated temperatures. Please consult our technical datasheet for derating curves above 100°C.
Q: How should I clean and sterilize this tubing?
Our silicone tubing can be cleaned with mild detergents and rinsed with distilled water. For sterilization, autoclaving at 121°C for 30 minutes is recommended (up to 50 cycles). Gamma irradiation (25-40 kGy) and ethylene oxide (EtO) are also suitable. Avoid prolonged exposure to strong oxidizing agents like concentrated nitric acid.
Q: Do you offer samples for testing?
Yes, we provide free samples (up to 1 meter) for qualified B2B buyers. Please contact our sales team with your application details and shipping address. We also offer paid sample kits with multiple durometers and wall thicknesses for comparative testing.
Q: What packaging options are available?
Standard packaging includes 25-meter coils, 50-meter spools, or custom cut lengths (1 m, 2 m, 5 m). For bulk orders, we offer 100-meter and 200-meter spools. Each coil is individually bagged in clean polyethylene to prevent contamination. Custom labeling and barcoding are available for OEM customers.
