Additional Information



  • Use pipes and fittings from the same manufacturer
  • Installation should be completed as per instructions and recommended safe practices must be followed.
  • Clean pipe and fittings with clean dry cloth to remove any dirt.
  • Keep pipe and fittings in the original packaging until used.
  • Cut off min. 25mm beyond the edge of the crack in case of any crack is discovered on the pipes.
  • Cut the pipe as square, i.e. perpendicular, as possible before making a joint.
  • Ensure no sharp edges are in contact with the fittings surface while inserting the pipe
  • Ensure proper alignment of pipe and fittings to avoid stress on the joints.
  • Ensure installation is done in such a way that there are no chances of air entrapment.
  • Use only Teflon tapes as thread sealant.
  • Always conduct hydraulic pressure testing after installation to detect any leaks and faults.
  • Wait for appropriate cure time before pressure testing. Fill lines slowly and allow air to bleed from the system prior to pressure testing.
  • Paint the pipes (water based paint) exposed to sunlight.
  • Provide additional support to the brass side of ASTM / brass transition or other metallic components to support the weight of the metal system.




  • Do not use metal hooks or nails to support / hold or put pressure on the pipes. Do not use strap and hangers with rough or sharp edges. Do not tighten the straps over the pipes
  • Never expose the pipe to open flame while trying to bend it.
  • Do not drop pipes on edges from heights. Do not drop heavy objects on pipes or walk on pipes.
  • Do not use air or gases for pressure testing.
  • Do not use any other petroleum or solvent -based sealant, adhesive, lubricant or fire stop material on ASTM pipes and fittings.
  • Do not use ASTM pipes and fittings for pneumatic applications.
  • Do not use the ASTM piping system to support any metallic components.
  • Do not use ASTM solvent cement that exceeds its shelf life, has become discoloured or has gelled.


Frequently asked questions (FAQs)



  • Why is Lead free material used in plumbing pipes and fittings?
  • It is scientifically proved that lead is harmful if consumed. It is found that lead can damage various systems of human body including reproductive system, nervous system and kidneys. It also can cause high blood pressure and anaemia. Formerly the presence of 0.3ppm of lead was allowed in drinking water pipes. Lead can be dissolved in water when it come in contact with water. Hence, it was banned recently and almost all companies are manufacturing lead free pipes.


  • What about health, safety, and fire toxic issues?
  • Tests performed in reputed universities and independent laboratories confirm that PVC-U is superior to copper/lead solder systems in terms of water quality effects and is “no more toxic than wood” in a fire. Finolex plumbing pipes and fittings are manufactured from lead free material hence making it the most favoured system in terms of health and safety.


  • Should specific type of primers and solvent cements be used on Finolex ASTM Plumbing pipes and fittings?
  • Finolex always recommends use of Finolex solvent cement which is specially manufactured to meet requirements of ASTM D 2564 Standards. All-purpose solvent cements are not recommended.


  • Can we use Finolex pipes with locally available fittings and vice-versa?
  • Finolex PVC-U pipes and fittings are manufactured from lead free PVC-U material. Finolex strongly recommends the use of pipes and fittings of the same manufacture. This ensures similar material and the best fit between pipes and fittings. Also in case of a problem the responsibility lies with only one supplier.


  • Is PVC-U pipe easier to install than alternative materials?
  • Finolex PVC-U pipes and fittings are very light in comparison with alternative conventional metal pipes and fittings available. They are easy to handle and transport. Finolex uses solvent cement welding system, it does not require any threading dies, welding/soldering torches, or electricity tools. Even an unskilled labour can complete installation.


  • Can Finolex ASTM plumbing pipes and fittings be used for outdoor installations?
  • Finolex ASTM plumbing pipes and fittings contain stabilizers to protect pipes against harmful UV rays present in sunlight. Even after several months of usage, the performance of pipes is not affected. PVC pipe used in permanent outdoor exposures is recommended to be protected by light coloured water based paint, not oil based.


  • What is the expected life of Finolex ASTM plumbing pipes and fittings?
  • Finolex plumbing pipes and fittings are not susceptible to corrosion, scale build up or electrolysis in areas where water, solid or atmospheric conditions are aggressive. The pipes are designed to serve for approx. 50 years. Finolex ASTM plumbing pipes provide a service life longer than alternative materials available in the market.
