  • UHP1000
    New ultra-compact and heavy-duty UHP1000 orbital weld head: Introducing the most compact closed orbital fusion weld head on the market with a capacity for tubing up to 1”. Same benefits as the UHP series but ability to handle larger tube sizes....

  • New ultra-compact and heavy-duty orbital weld head up to 1”

    Introducing the most compact closed orbital fusion weld head up to 1”: with nearly the same duty cycle as the UHP 500, the new UHP 1000 can handle larger tube sizes and specifically, larger coaxial tube sizes.

    The axial and radial dimensions of the weld head are extremely compact with the capability to weld up to 1” tube!

    Savings ahead: with Polysoude UHP weld head range you can adapt up to 3 different drive modules (UHP 250 module 1/16” – 1/4”, UHP 500 module 1/8” – 1/2”, UHP 1000 module 1/4” – 1”) on the same handle.


    Width: 1” (axial), 2.6” (radial)

    Range: 1/4" (6.35mm) to 1” (25.4mm)
    Max. tube thickness: 1.6mm

    Estimated number of welds per hour: 12

    Cooling: air-cooled

    Closing: precise knurled knobs

    Tube clamp inserts: titanium TCI with Exclusive Flex and Quick-Lock mechanism and Life Warranty

    - Unique design allowing flexibility

    - Compatible with the standards by respecting the requirements of non-contamination
