Silicon Tubing with Reinforcement (Fabric) and Exterior Cover

Silicon-Schlauch TP Rot

Description / Construction

TP RED is a peroxide-cured silicon tubing with an inner reinforcement layer and a translucent or colored exterior cover for high-temperature usages. This reinforcement provides a high pressure resistance.

The table “Specifications” (see reverse page) provides an overview regarding feasible dimensions as well as technical data and reinforcement types. Standard color is red – other colors may be available upon request. A minimum order of 100 m applies for dimensions that are not kept as bulk stock.

Based on the nominal sizes, the following reinforcement materials (fabric) are being used. Polyester monofilaments (PES Mono up to +160 °C), Polyester yarn (up to +160 °C) and glass silk yarn (up to +180 °C). In addition, an reinforcement made of Aramid fibers (up to +180 °C) can also be provided upon request. The suitability of the reinforcement is primarily dependent on the temperature and/or movement. Glass silk demonstrates a lower dynamic load capacity than Polyester, whereas the tensile strength of glass silk and Polyester is virtually identical. However, breakage by movement faster occurs with glass silk than with Polyester, but, on the other hand, it is recommended for higher temperature exposure. In total, Aramid fibers demonstrate the best properties.

Properties of Pressure Tubing Reinforcements

Reinforcement Designation Presentation Textile Temperature Resistance
PES-MF Polyester multifilament (PET) Yarn Up to 160 °C
PES-Mono Polyester monofilament (PET) Monofil Up to 160 °C
Glass silk E-glass Yarn Up to 180 °C
Aramid Aramid fiber Yarn Up to 180 °C

All TP RED tubing is

  • Tasteless and odorless
  • Free from plasticizers
  • Physiologically and toxicologically harmless
  • Excellent resistance to weather, aging and light..

Primary application of TP RED tubing applies to the beverage and food industry, packaging industry (filling plants), machine and plant construction as well as electric industry (cooling systems).

Chemical Resistance

TP RED tubing is suitable for the transfer of almost all food materials, pharmaceutical media, weak acids or alkaline solutions, polar solvents, many alcohols, phenol, ozone and oxygen. Higher molecular weight non-polar hydrocarbons may cause swelling. Permanent steam exposure accelerates the aging process. A compatibility list as well as information regarding “steam and silicon” can be found at

Temperature Resistance

TP RED tubing can be used in a temperature range of -60 °C to +180 °C (depending on the reinforcement). For further information please refer to the table “Properties of Pressure Tubing Reinforcements”.


Nominal sizes of ID 3-50 mm are available. TP RED tubing is available in 60-75 Shore hardness (product-depending). Routine production is based on materials that meet the following requirements (applicable only to interior tubing if colored exterior cover is used):

  • BfR XV Silicone
  • FDA 21 CFR 177.2600
  • USP Class VI
