Quick Answer
Food-grade transparent silicone tubing for transferring compatible liquids or air in food, beverage, dispensing, and processing equipment. Inside diameter, outside diameter, wall thickness, length, hardness, tolerances, compliance documentation, samples, and packaging are available upon request.
Food-grade transparent silicone tubing is a clear, flexible tube intended for transferring compatible liquids or air in food and beverage equipment. Inside diameter, outside diameter, wall thickness, length, Shore A hardness, operating temperature, pressure rating, and specific food-contact compliance are available upon request and must be confirmed for the intended application.
Food Grade Transparent Silicone Tubing, 50 Shore A
Food grade transparent silicone tubing at 50 Shore A hardness is a flexible, platinum-cured tube designed for direct contact with food, beverages, and water, offering strong resistance to extreme temperatures alongside FDA-compliant safety.
Product Overview
This tubing is molded from platinum-cured silicone rather than peroxide-cured formulations, a distinction that matters for food and beverage contact applications since platinum curing avoids the byproducts associated with peroxide-based vulcanization. At 50 Shore A hardness, the tubing sits at a soft-to-medium point on the durometer scale, giving it strong flexibility for routing through tight bends while still maintaining enough structural integrity to resist kinking under normal handling. The transparent, ultra-clear finish allows visual monitoring of fluid flow, which is a common requirement in food processing, brewing, and beverage dispensing systems.

Why Platinum-Cured Silicone for Food Contact Applications
Platinum-cured silicone tubing is preferred over peroxide-cured alternatives for food and beverage applications because the platinum catalyst process leaves no harmful residual byproducts that could migrate into food or liquid passing through the tube. This tubing type also resists UV degradation and does not age, melt, or burn under normal use conditions, supporting long service life in both indoor processing lines and outdoor equipment exposed to sunlight. Because silicone is naturally chemically inert, it does not impart taste or odor to the fluids it carries, an important property for dairy, beverage, and drinking water transfer systems.
Temperature and Chemical Performance
- Withstands a broad operating range from approximately negative 100 degrees Fahrenheit up to 500 degrees Fahrenheit in general use, with a 350 degree Fahrenheit ceiling specifically for NSF-rated food applications.
- Maintains flexibility and durability across both freezing cold and high heat conditions without becoming brittle or losing shape.
- Resists ozone and general environmental degradation, supporting reliable performance in both indoor and outdoor installation settings.
- Compatible with common sanitizing and cleaning processes used in food and dairy processing environments, including steam sterilization in many formulations.
Regulatory Compliance Standards
- Complies with FDA 21 CFR 177 requirements governing indirect food additives and food-contact materials.
- Meets NSF standards for water and beverage contact applications.
- Conforms to 3-A Sanitary Standards, a benchmark widely used in dairy and food processing equipment design.
- Manufactured free of BPA and latex, addressing common allergen and chemical safety concerns in food-contact products.
Common Applications
- General sanitary tubing applications in commercial kitchens and food service equipment requiring visual flow monitoring through clear tubing walls.
- Food and beverage processing lines requiring safe, non-reactive fluid transfer tubing.
- Dairy processing equipment, where hygienic material compatibility with milk and dairy liquids is essential.
- Drinking water transfer systems, including home brewing, filtration, and dispensing setups.
- Pharmaceutical and laboratory fluid handling systems requiring chemically inert, temperature-resistant tubing.
Frequently Asked Questions
What sizes of transparent silicone tubing are available?
Inside diameter, outside diameter, wall thickness, cut length, and coil length are available upon request. No standard size range has been confirmed for this product page. Provide the required dimensions, tolerances, fitting size, flow conditions, and quantity so manufacturing feasibility and availability can be evaluated.
Is this silicone tubing certified for food contact?
The product is identified as food-grade silicone tubing, but no specific regulation, certificate, or completed test has been provided. Required food-contact standards, target market, food type, contact duration, and operating temperature must be confirmed before selecting the silicone compound and preparing the applicable documentation.
Can the tubing hardness and dimensions be customized?
Yes. Inside diameter, outside diameter, wall thickness, length, Shore A hardness, transparency, tolerances, and packaging can be evaluated for customization. The selected hardness and wall profile must support the required flexibility, fitting retention, bend geometry, flow condition, and installation method.
Can this tubing be used with hot liquids or steam?
No confirmed operating temperature or steam-cycle specification has been provided. The maximum continuous temperature, peak temperature, exposure duration, pressure, cleaning cycle, and contacted medium must be supplied. The selected compound and finished tubing should then be validated under the actual operating conditions.
Is the tubing suitable for pressure, vacuum, or pump applications?
No pressure, vacuum, burst, collapse, or pumping rating has been confirmed. Suitability depends on the inside diameter, wall thickness, hardness, unsupported length, bend radius, connection method, temperature, medium, and equipment cycle. Provide these conditions so the tubing specification and required validation can be evaluated.
Are samples, MOQ, tooling, and lead time available?
Sample availability, MOQ, tooling requirements, and lead time are available upon request. They depend on the required dimensions, silicone compound, hardness, tolerances, length, compliance documentation, inspection plan, packaging, order quantity, and estimated annual volume.
