Unasco Yellow Gas Seal Tape

Brand: Unasco

Unasco Yellow Gas Seal Tape is a high-density PTFE thread seal tape designed for natural gas lines, gas fittings, and threaded gas connections. Its thick, full-density construction helps create a dependable seal while using less tape than lower-density alternatives.

Unlike many stretched thread seal tapes, Unasco Yellow Gas Seal Tape retains its full density during manufacturing. This reduces porosity and helps prevent shredding, stringing, and excess tape waste, making installation cleaner and easier.

Widely used throughout the gas industry, this yellow Teflon gas tape is approved by relevant authorities and colour-coded for quick identification by gas fitters, technicians, and inspectors.

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

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
