Installation Instructions for UNALOK Hose

Tools Needed: Measuring tape, chalk, knife, hacksaw, clamps, and wrenches.

  1. Measure and mark the required length of hose. Add a little extra length for trimming (see photo) and lateral overlap.
  2. Cut off the marked length of hose plus the extra length, using a sharp wet cutting tool, such as a knife.
  3. Pull the cut surfaces apart so that the steel helix can be pulled out of the rubber. Cut off the steel helix.
  4. Place the two halves of UNALOK coupling-parts 1 and 2 at the position marked and clamp together.
  5. Bolt the two halves of the coupling through the joining flanges, inspect the lining of the hose at frequent intervals while tightening bolts. The end of the hose should extend about 1/8” beyond the coupling flange.
  6. Installation is complete when corrugated deformations become clearly visible in the bore of the hose.
  7. Place a sealing gasket between the two couplings and bolt the coupling flanges together. The hose should be attached to a supporting structure over its entire length, but particularly in the area of bends. Conventional hose clamps can be used to prevent undesirable movement of the hose.
