Description

The Quick-Lock BIG was developed as a separable sleeve for the rehabilitation of man-entry pipeline systems. With the same trusted Quick-Lock technology, this heavy-duty system is engineered to provide a durable and permanent solution for typical types of damage including leaking pipe joints and radial cracking. Nominal size range DN 800 / 32” and above.

The Quick-Lock BIG consists of two-, three-, or four-part segments (shells), depending on the nominal size; one seal; and one set of screws. Made from high-grade stainless steel and an EPDM rubber gasket, Quick-Lock BIG offers superior corrosion resistance and a secure, watertight seal. Its trenchless installation method eliminates the need for digging, ensuring minimal disruption while delivering a fast and efficient repair. 

How it works: 

  • The Quick-Lock BIG uses the principle of compression and is made from the materials 316L and EPDM.
  • The separable sleeve is inserted into the pipeline system through the man-entry opening.
  • The Quick-Lock BIG clamping tool is used to spread it out at the site of the damage.
