Custom Silicone Tubing Manufacturer

Silicone Tubing Specifications

Silicone tubing is flexible and elastic, holding up to tight bends and frequent movement without cracking. Standard specifications:

• Platinum-cured and Liveo C6/Q7 medical-grade compounds, food-grade and biocompatible
• -50°C to 250°C (-58°F to 482°F) operating range, autoclavable to 134°C (273°F)
• 5 to 200 psi pressure rating, customizable to your application
• Inner diameter from 0.5 mm, wall thickness from 0.3 mm, custom lengths
• UV, weathering, and chemical resistant
• Reinforced options available (fiberglass or wire) for high-purity or corrosive applications
• Shore A 30 to 80 across our platinum-cured extrusion grades, tensile strength 7 to 10 MPa, elongation 150% to 600%, tear strength 16 to 35 KN/m

How Our Silicone Tubing Is Made

Silicone tubing is extruded, not molded: uncured silicone is pushed continuously through a precision die, then cured in-line to fix the profile at your target inner diameter, outer diameter, and wall thickness. Because the profile is continuous, there's no parting line and no flash to trim, unlike compression or injection molded parts. Wall concentricity and dimensional consistency are checked throughout the run, not just at the ends of a batch. See our extrusion services page for the full process.

Choosing the Right Shore A Hardness

Softer durometers, in the Shore A 30 to 40 range, suit tight-bend routing and applications where the tube needs to flex repeatedly without kinking. Mid-range durometers, Shore A 50 to 60, balance flexibility with enough wall stiffness to resist collapsing under vacuum or light pressure. Firmer durometers, Shore A 70 to 80, hold their shape under higher pressure and see less deformation under repeated compression, such as with peristaltic pump tubing. If you don't have a target durometer, tell us the pressure, bend radius, and cycle requirements and we'll recommend one.

Tell Us What You Need

Send us your inner diameter, outer diameter, and length, along with wall thickness and Shore A hardness if you have a target. Wall thickness and durometer work together to set the pressure rating and flex characteristics of the finished tube: thinner walls and softer compounds suit tight-bend, low-pressure routing, while thicker walls and firmer durometers hold shape under higher pressure or vacuum. If you're not sure where to land, tell us the application and operating conditions and we'll recommend a starting spec.

Color and surface texture are confirmed at the same time as material grade. We match the compound and confirm dimensions during DFM review, before any tooling cost is committed.

Industries We Serve

We supply silicone tubing across applications where flexibility, temperature range, or biocompatibility rule out standard rubber or plastic tubing:

• Medical devices: catheters, syringes, and drug-delivery lines, in USP Class VI and medical-grade compounds
• Food and beverage: transfer lines and dispensing equipment in food-grade silicone
• Pharmaceutical manufacturing: single-use assemblies and peristaltic pump lines
• Chemical processing and handling: reinforced tubing for corrosive or high-purity fluid transfer
• Hydraulic and pneumatic systems: pressure-rated tubing to 200 psi
• Bio-research and laboratory: fluid transfer and tubing sets, autoclavable to 134°C

Certifications

FDA, CE, and UL certification available, along with compliance to ASTM and ISO standards. Tell us your requirement and we confirm it during DFM. Custom packaging and labeling are also available on request.

Cleaning, Sterilization, and Joining

Silicone tubing can be steam autoclaved, gamma or e-beam irradiated, or chemically sterilized with common disinfectants, depending on the compound and wall thickness. Our tubing is rated for repeated autoclave cycles at 134°C (273°F). Silicone doesn't solvent-weld the way rigid plastics do, so tubing is typically joined with barbed fittings, where the tube's own elasticity creates the seal, or with a silicone-specific adhesive for permanent bonds. Tell us your connection method and we confirm compatibility during DFM.
