1. Product Overview
Our solid silicone rubber tubing is a high-performance elastomeric product manufactured from 100% premium-grade silicone polymer. This tubing is specifically formulated to provide an exceptional balance of flexibility, longevity, and resistance to environmental stressors. It is an ideal sealing, insulating, or protective component in assemblies requiring a reliable, non-porous material that maintains its properties under continuous stress. Available in a comprehensive range of standard and custom sizes, durometers (hardness), and colors, our solid silicone rubber tubing can be tailored to meet precise technical specifications and application requirements.
2. Key Features
- Exceptional Temperature Range: Performs consistently in temperatures from -60°C to 230°C (-76°F to 446°F), withstanding both prolonged heat aging and extreme cold without cracking or becoming brittle.
- Superior Chemical & Environmental Resistance: Resists oxidation, ozone, UV radiation, and many chemicals, ensuring long-term integrity in both indoor and outdoor settings.
- Excellent Electrical Insulation Properties: Provides high dielectric strength, making it a safe and reliable choice for electrical insulation and component protection.
- High Tensile Strength & Tear Resistance: The solid construction offers enhanced mechanical properties compared to sponge or hollow tubing, resisting abrasion, punctures, and physical deformation.
- Biocompatible & Odorless: Compliant with FDA, USP Class VI, and other relevant standards for applications in food, medical, and pharmaceutical industries where material purity is critical.
- Flexibility & Compression Set Resistance: Remains flexible across the temperature spectrum and returns to its original shape after compression, ensuring lasting seal integrity.

4. Application Scenarios
Our solid silicone rubber tubing is a versatile component across multiple high-tech and industrial sectors:
- Automotive & Aerospace: Used as protective sleeving for wiring harnesses, grommets, vibration dampeners, and seals in engines and avionics due to its heat and fuel resistance.
- Medical & Pharmaceutical: Ideal for peristaltic pump tubing, fluid transfer lines, seals in diagnostic equipment, and protective covers, leveraging its biocompatibility and sterilizability (autoclave, ETO, gamma).
- Food & Beverage: Employed in food processing machinery as seals, gaskets, and tubing for non-reactive, odorless transfer of ingredients.
- Electrical & Electronics: Serves as high-temperature insulation for wires and cables, protective jacketing, and seals in lighting, appliances, and power distribution systems.
- Industrial Machinery: Functions as durable seals, hydraulic/pneumatic line protection, and rollers in high-temperature or chemically exposed environments.
- Laboratory & Analytical Equipment: Used for fluid handling in analytical instruments where chemical inertness and purity are paramount.
5. Advantages Over Alternative Materials
Choosing solid silicone rubber tubing provides distinct benefits that other elastomers cannot match:
- vs. PVC or Rubber Tubing: Far superior high-temperature performance and flexibility in cold conditions. Does not contain plasticizers that can leach out, causing hardening and failure.
- vs. Sponge Silicone Tubing: Offers greater mechanical strength, crush resistance, and provides a true barrier against fluids and gases, unlike porous sponge materials.
- vs. Fluorosilicone or FKM: While offering excellent fuel and oil resistance, our standard solid silicone rubber tubing provides a more cost-effective solution for applications not involving aggressive hydrocarbons, with better low-temperature flexibility.
- Long-Term Cost Efficiency: Its exceptional durability and resistance to aging reduce downtime, maintenance costs, and frequency of replacement, offering a lower total cost of ownership.

7. Frequently Asked Questions (FAQ)
Q1: What is the main difference between solid and sponge silicone tubing?
A: Solid silicone tubing is a dense, non-porous material offering a complete barrier to fluids and gases, with higher mechanical strength. Sponge silicone is a cellular, porous material primarily used for thermal insulation, cushioning, and lightweight sealing where compression is needed but a complete fluid barrier is not required.
Q2: Can your solid silicone rubber tubing be sterilized?
A: Yes. Our medical and food-grade tubing formulations are designed to withstand common sterilization methods including autoclaving (steam), gamma irradiation, and ethylene oxide (ETO) gas without significant degradation of properties.
Q3: Do you offer custom sizes and colors?
A: Absolutely. We specialize in custom manufacturing. We can produce solid silicone rubber tubing in virtually any inner/outer diameter, wall thickness, and a wide spectrum of colors to match your corporate or safety coding requirements. Minimum order quantities apply for custom profiles.
Q4: What is the lead time for standard and custom orders?
A: Standard sizes and durometers are typically available for shipment within 7-14 days. Lead times for custom formulations or sizes depend on the complexity and quantity, generally ranging from 4-6 weeks. We provide firm timelines upon order confirmation.
Q5: Is this tubing suitable for continuous contact with food or drinking water?
A: Yes, when specified. We offer compliant formulations that meet FDA CFR 21.177.2600 for food contact and other relevant international standards (e.g., LFGB, BfR). Please request the specific compliance documentation for your application.
