Product Description

Extreme-Duty Silicone Tubing - 3mm ID x 7mm OD

The Ultimate Solution for Protection and Pressure

When your application demands uncompromising strength, our 3x7mm silicone tubing is the answer. Engineered with an extraordinary 2mm thick wall, this is the most robust and resilient tube in our 3mm inner diameter series. It is designed not just to transfer fluids, but to protect, insulate, and perform flawlessly in the most hostile physical and high-pressure environments.

Consider it less of a tube and more of a flexible armor for your critical systems.

Why Choose the 3x7mm Extreme-Duty Tube?

  • Virtually Crush-Proof: The massive 2mm wall provides exceptional structural integrity, resisting crushing, impacts, and physical abuse on the factory floor or in the field.

  • Maximum Pressure Rating: Engineered to contain the highest pressures in our non-reinforced silicone tubing lineup. Ideal for demanding peristaltic pumps and high-pressure dosing systems.

  • Absolute Kink Immunity: The inherent stiffness from its thick wall makes kinking a non-issue, ensuring a constant, unrestricted flow path no matter how it's routed.

  • Superior Protective Sleeving: Its primary function can be to act as a durable, insulating sleeve. Protect delicate wires, smaller tubes, or fiber optics from abrasion, heat, and impact.

Applications Spotlight: For When Failure is Not an Option

The 3x7mm tubing excels where all other standard tubes fall short.


  • Protective Sleeving & Cable Armor: Slide over wire harnesses or pneumatic lines in robotic arms and automated machinery to provide ultimate protection against repeated motion, abrasion, and pinching.

  • High-Pressure Chemical Dosing: The perfect choice for systems delivering concentrated or aggressive chemicals under high pressure, where leaks are catastrophic.

  • Industrial Equipment: Used as durable conduits on heavy machinery, construction equipment, and agricultural vehicles, where components are exposed to harsh conditions.

  • Structural & Insulating Component: Its rigidity and thick wall allow it to be used as a standalone structural element, spacer, or thermal/electrical insulator in complex assemblies.


Equip your most critical applications with the strength and reliability they deserve.
