Calibration Gas Tubing connects regulators to detectors without compromising sample integrity. Available in inert PTFE for reactive gases and flexible Tygon or PVC for non-reactive mixtures, it resists adsorption and permeation to ensure accurate delivery. Correct tubing selection is essential for reliable calibration across GCC and Indian gas detection programmes.
Calibration Gas Tubing is the critical link between the regulator and the instrument under test, and the choice of material directly affects calibration accuracy. Reactive gases such as hydrogen sulphide, chlorine and other adsorptive species require chemically inert PTFE tubing, which resists absorption and permeation so that the concentration reaching the sensor matches the certified cylinder value. For non-reactive gases such as methane, carbon dioxide and oxygen mixtures, flexible Tygon or PVC tubing offers an economical and easy-to-handle alternative. Using the wrong tubing can cause reactive gas to be lost to the tube wall, producing false low readings and unreliable calibrations.
Selecting the correct grade therefore protects both the accuracy of the result and the confidence of any subsequent audit. The tubing is supplied with a consistent internal bore that promotes stable, predictable flow and connects readily to standard regulator outlets and detector inlets, making it simple to assemble portable kits or plumb fixed calibration benches. Its clean inner surface minimises the memory effects that can carry contamination between successive tests, which is especially important when moving between different gas concentrations. Suited to oil and gas terminals, petrochemical plants, chemical works, water treatment sites and general manufacturing across the GCC and India, the range covers both reactive and non-reactive needs. Filosha Industrial supplies calibration gas tubing in cut lengths and continuous rolls with a choice of diameters, backed by regional stock and technical guidance, so maintenance teams can match tubing to gas type and achieve accurate, repeatable calibration every time.
