3M QSLV-M 2-500 Cold Shrink Splice Kit 750 MCM Black 5.25 in

SKU CH-RVGV-S03RX

Cold-shrink EPDM rubber splice kit covers 2 AWG to 750 MCM wire, shrinks from 1.6 in to .4 in ID, 5.25 in long, rated to 266 °F

  • Splices 2 AWG to 750 MCM conductors
  • Cold-shrink EPDM rubber installs without heat tools
  • UV-resistant black tubing withstands outdoor exposure
  • Operates from -40 °F to 266 °F continuous
  • 1 000 V dielectric strength for reliable insulation

Cold Shrink Splice Kit 2 AWG–750 MCM

The 3M QSLV-M cold shrink splice kit fits wire sizes from 2 AWG up to 750 MCM and comes as an individual piece. It is designed for electricians who need a quick, tool-free splice on medium-voltage cables. The kit uses EPDM rubber tubing that shrinks without a heat source. Buyers who require a heat-shrink alternative or a kit with multiple pieces will not be served by this product.

UV-Resistant EPDM Rubber -40 °F to 266 °F

The tubing is UV-light-resistant and rated for a continuous temperature range of -40 degrees to 266 degrees F. It has a dielectric strength of 1,000 V and contains no flame-retardant additive or adhesive lining. The material contracts from a 1.6 in inner diameter before shrinking to a 0.4 in inner diameter after shrinking. Installers needing a flame-retardant or adhesive-lined sleeve must look elsewhere.

Individual Piece 5.25 in Length Black

Each package contains a single black splice tube measuring 5.25 in long. No additional connectors, sealants or installation tools are bundled with the kit. The cold-shrink design eliminates the need for a torch or heat gun during installation. Users who expect a multi-piece assortment or integrated connector hardware will need to source those separately.

Questions about this item

How do I install the 3M QSLV-M cold shrink splice on a 750 MCM cable, and what step is often missed?

Slide the pre-expanded tube over the prepared joint, then unwind the core smoothly; the step often missed is ensuring the core is removed in one continuous motion so the EPDM rubber grips evenly at the 0.4 in recovered diameter.

What maintenance or replacement will the 3M QSLV-M splice need after installation?

The EPDM rubber splice is UV-light-resistant and rated from -40 to 266 Degrees F; it requires no scheduled maintenance and is replaced only if physical damage or insulation breakdown occurs.

What is the first limit reached on the 3M QSLV-M splice under sustained high-temperature operation?

The maximum temperature rating of 266 Degrees F is the first limit; continuous exposure above this degrades the EPDM material and dielectric strength of 1,000 V.
