Unasco Yellow Gas Seal Tape

Brand: Unasco Inc
Unasco Yellow Gas Seal Tape is a Teflon thread sealing tape designed specifically for gas lines. Unasco Yellow Gas Seal Tape is a thick, full or maximum density thread sealing tape.

Unlike most thread sealing tapes on the market Unasco Yellow Gas Seal Tape has not been stretched during the manufacturing process.

Stretching lowers the apparent density of tape by increasing its porosity.

As stretched tape is more porous, more is required to obtain an effective seal.

A stretched tape is also flimsy and difficult to work with. It is more likely to shred and string. The amount of tape wasted is high.

With Unasco’s full density Yellow Gas Seal Tape these problems are avoided.

Unasco Yellow Gas Seal Tape is approved by relevant authorities and used by the gas industry world-wide.

Also, Unasco Yellow Gas Seal Tape is color-coded yellow so fitters and inspectors can easily recognize it as an approved tape.
Features
  • Compatible with a broad range of gases and liquids 
  • Compatible with a broad range of piping materials 
  • Will not harden or crack on the joint 
  • No curing time 
  • Effective across a broad range of temperatures 
  • Acts as a thread lubricant and anti-seize

Typical Applications

Unasco Yellow Gas Seal Tape is manufactured from Teflon. 

Teflon PTFE resin is a polymer consisting of recurring tetrafluoroethylene monomers whose formula is (CF2 - CF2)n. It is one of the most inert substances known.

Therefore, it is compatible with a very wide range of materials.

It can be used on pipe made from galvanized steel, iron, brass, copper, aluminium, stainless steel, polyethylene, polypropylene, PVC, CPVC, ABS and fibreglass.

It can also be used on pipes carrying the following materials:
  • Acids, concentrated
  • Acids, dilute
  • Air, compressed
  • Alcohols
  • Aliphatic solvents
  • Ammonia, liquid
  • Aromatic solvents
  • Caustics, concentrated
  • Caustics, dilute
  • Chlorinated solvents
  • Cutting oils
  • Diesel fuel oil
  • Ethylene glycol
  • Fatty acids
  • Gasohol
  • Glycerine
  • Heating oils
  • Hydraulic fluids
  • Hydraulic oils
  • Hydrogen, gaseous and liquid
  • Inert gases, gaseous and liquid
  • Jet fuel
  • Kerosene
  • Ketones
  • Liquid Petroleum Gas
  • Mineral oils
  • Natural gas
  • Nitrogen, gaseous and liquid
  • Petroleum solvents
  • Soap, liquid
  • Steam
  • Vegetable oils
  • Water
