Elastomeric Rubber ST Tubes

K-FLEX® ST products meet all the requirements demanded by civil and industrial refrigeration, air conditioning, plumbing, insulation of tanks, fittings, water pipes and all other applications that need thermal insulation.

Elastomeric Rubber ST Tubes

Description

K-FLEX ST TUBES is suitable for all applications both civil and industrial that require the use of insulation material, without neglecting the price/quality relationship, refrigeration, air-conditioning, heating and plumbing, tanks, pipe fittings and water ducts.

Applications

K-FLEX® products cover a range of temperature for applications including cryogenic plants to chilled
water systems, and from domestic hot water systems to solar thermal plants. Their high resistance to water vapour diffusion is a key feature of all K-FLEX® closed cell elastomeric insulation materials.

Typical applications include:

  • Refrigeration and air-conditioning systems and plumbing.
  • Industrial, chemical and pharmaceutical plant engineering.
  • Insulation of pipes, fittings and other equipment.
  • Insulation of tanks, solar systems.
  • OEM applications.
