Product Overview
HONG YE SILICONE’s Foamed Silicone Rubber Tube is a professional tubular foamed silicone product, integrating flexibility, pressure resistance and sealing performance, designed to solve the pain points of traditional rubber tubes (poor flexibility, easy leakage, weak pressure resistance) in fluid conveying and component protection. As a 2-component addition curing product, it is formed by precision extrusion and foaming, with a seamless outer surface and uniform closed-cell foam inner layer—ensuring no fluid leakage, good thermal insulation and sound insulation, while maintaining ultra-high flexibility that allows bending and twisting without cracking or deformation. Made of high-purity Silicone raw materials, it is non-toxic, odorless, and free of harmful substances, adapting to various harsh working environments. Compatible with most of our core silicone products, it provides a one-stop solution for B2B buyers in fluid conveying, heat insulation, and component protection scenarios.

Product Features & Advantages
1. Ultra-High Flexibility & Bendability: Bending radius as small as 5× the tube outer diameter, can be bent, twisted and routed freely in narrow spaces or complex equipment, no cracking, no deformation, solving the problem of traditional rubber tubes being stiff and difficult to install in confined areas.
2. High Pressure Resistance & Leak-Proof: Working pressure up to 1.2MPa, burst pressure 3 times the rated pressure, seamless integral structure and closed-cell foam inner layer effectively prevent fluid leakage, ensuring stable fluid conveying even in high-pressure working conditions.
3. Dual Insulation Performance: Closed-cell foam structure provides excellent thermal insulation and sound insulation—effectively isolating temperature changes to protect sensitive fluids, and reducing noise generated by fluid flow, suitable for high-temperature or low-temperature fluid conveying scenarios.
4. Durable & Environmentally Friendly: Made of high-purity addition curing silicone, non-toxic, odorless, no harmful substances, no pollution to conveyed fluids; excellent aging resistance, no brittle fracture, no performance degradation after long-term use (service life ≥5 years in normal working conditions).
5. Easy Installation & Customization: Lightweight, easy to cut to any length according to actual needs, no professional tools required; size (inner diameter, outer diameter, wall thickness), color, and foam density can be customized to adapt to different fluid conveying and installation requirements.
6. Wide Compatibility: Compatible with HONG YE SILICONE’s industrial Mold Silicone rubber (for tube fitting molding) and liquid tank silicone (for fluid storage matching), forming a complete fluid conveying solution, enabling one-stop procurement for B2B buyers.
How to Use
1. Preparation: According to the actual fluid conveying requirements, select the appropriate size of foamed silicone rubber tube, or customize the size with our technical team.
2. Cutting: Use ordinary cutting tools to cut the tube to the required length, ensuring the cut is flat and free of burrs (avoid affecting sealing performance when connecting fittings).
3. Installation: Insert the tube into the matching fittings (molded with our industrial mold silicone rubber), tighten the clamp appropriately to ensure a tight connection, no leakage; the tube can be bent and routed freely according to the equipment layout.
4. Maintenance: Regularly check the tube surface for damage, aging or leakage; avoid contact with sharp objects and strong corrosive substances (for corrosive fluid scenarios, select our customized anti-corrosion model); clean the tube inner wall regularly to ensure smooth fluid conveying.
