DAM/BLOK™ Splice Kits

DAM/BLOK™ Splice Kits

DAM/BLOK™ Splice Kits are comprised of a unique combination of up to three levels of sealing protection that produce a highly, reliable, full-ocean depth pressure splice. Mechanical seals, chemical bonds, positive water blocking, and a polyurethane over-mold work together to prevent leak water present in the cable or water outside the cable from passing through the splice to the electrical connection.

Radial squeeze resulting from the compression dams prevents any leaking water migrating along the non–bondable elements from passing through.  No driving force present can overcome the persisting interference due to the isostatic nature of the seal (the same pressure exists on all sides of the seal).  The DAM/BLOK™ Splice uses ambient pressure to prevent internal water migration.

Features & Benefits:
  • Precast polyurethane compression dams, waterblock solder pins and polyurethane overmold prevent water penetration to 3500 psi
    • The compression dams prevent leakwater penetration along non-bondable surfaces
    • Conductors are soldered to contacts and connected to pins which are sealed inside the compression dam
    • Polyurethane overmold encapsulates the splice and produces a chemical bond to all surfaces of the compression dams
  • Isostatic nature of the seal (the same pressure exists on all sides of the seal) prevents water migration at any depth
The DAM/BLOK Kit contains:
  • Room Temperature Cure Polyurethane
  • QWIK-Pin Waterblock Contact Pins
  • Precision Precast Compression Dams
  • Disposable Mold
