Cross-Linked Polyethylene Piping

Cross-linked polyethylene piping(YUKARON XL TM Pipe)

We started manufacturing and selling cross-linked polyethylene piping in 1967. This is a piping material with outstanding durability, corrosion resistance, and heat resistance, and has a proven track record of use in a wide range of applications such as cold and hot water supply piping for detached houses and condominiums, hot water floor heating, and snow melting pipes.


  • Hygienic, safe, clean and reliable piping that does not affect water quality, and makes it difficult for red water to easily occur and scale to adhere.
  • Outstanding quality featuring earthquake resistance, cold resistance, and heat resistance, as well as long-term resistance to leakage.
  • Excellent long-term durability thanks to superior resistance to chlorine and chemicals such as acids and alkalis.
  • Light and flexible piping comes in long lengths, making it extremely easy to handle and install without requiring thread cutting.
  • Excellent pipe strength with strong resistance to creep and breakage.

Header Systems

Header systems

In the sheath pipe header construction method, cold and hot water is supplied through the YUKALON XLTM Pipe (cross-linked polyethylene pipe) to each fixture from headers installed in the pipe shaft or indoors at places with inspection ports.

Joint-Branched Piping Systems

Joint-Branched Piping Systems

The joint-branched piping system features excellent workability and uses EF couplings with the same piping method as a conventional one.

XL EF Prefabricated Piping Systems

This cold and hot water supply piping set is prefabricated using XL EF couplings and provides stable quality.

XL EF prefabricated piping systems


  • Labor-Saving, On-Site Construction
    Most of the connections are pre-processed in the factory, which simplifies the on-site construction and saves labor.
  • Cost Reduction
    Reduced number of labor-hours on site can reduce the total costs.
  • High Quality
    High quality is enabled by stable connections processed in the factory.
  • Pipe Type Can Be Selected
    The pipe type can be selected from bare pipe, covered pipe, sheathed pipe and protected pipe.
  • Tip Couplings Can Also Be Selected
    The tip couplings can be selected from one-touch and mechanical types.

One-Touch Coupling with Insertion Confirmation

One-Touch Coupling with Insertion Confirmation


  • Insertion is Easy to Confirm
    Transparent plastic is used for the pipe insertion part, so it is easy to see at a glance how the pipe is inserted during and after construction.
  • Weight Reduction
    Reduced weight and cost competitiveness have been improved by using plastic parts.
  • Insertion is Confirmed with Sound
    There is a “click” when the pipe is completely inserted, which makes it easier to know when the construction is complete.
  • Inner Diameter Seal
    An inner seal is used that is less susceptible to external pipe scratches. Compared to O-rings, the two fluororubber seal rings used are more difficult to remove, and improve water-stop performance and reliability.
    One-touch coupling with insertion confirmation
  • Eco-Friendly
    The copper alloy mainly used for the screw part is lead-free bronze.
