Krimpa-Seal™ Installation Instructions
Butt Connectors

  1. Strip the wire 5/16 ".
  2. Select a connector that matches the wire gauge and insert the wire into the connector barrel.
  3. Make sure the wire is properly seated and crimp the connector using an insulated connector crimping tool nest that matches the color or gauge of the connector. Do not crimp the solder sleeve.
  4. Repeat steps 1 thru 3 for the other side.
  5. Apply heat evenly around the length of the tubing (including the crimp area) from the center out to the ends until the tubing fully recovers and the adhesive flows. Remove from the heat and let cool for a SEALED connection.

 

Rings, Spades, & Slip-Ons

  1. Strip the wire 5/16"
  2. Select a connector that matches the wire gauge and insert the wire into the terminal barrel.
  3. Make sure the wire is properly seated and crimp the terminal barrel using an insulated connector crimping tool nest that matches the color or gauge of the terminal.
  4. Apply heat evenly around the length of the tubing (including the crimp area) until the tubing fully recovers and the adhesive flows. Remove from the heat and let cool for a SEALED connection.

 

For Best Results:

  • Use a heat device of at least 400° F
  • When using an open flame, do not isolate the flame on one area of the tubing
  • Distribute the heat evenly
  • Overheating the connector may cause damage to the tubing
  • Rating: 105° C
  • 600V maximum building wire
  • 1000V maximum in signs and fixtures
  • Not for Multiple Wire Connectors

 

Limiting Oxygen Index (LOI)
The ratio of how much oxygen - as compared to other gases - needs to be present in the air surrounding a particular material in order for that material to burn. The fact that Earth's normal atmospheric air contains around 21% oxygen is used a reference point when materials are classified into burn categories that are based on Limiting Oxygen Index. Substances that are combustible in air containing less than 21% oxygen are considered flammable, while those that burn in the range of anything greater than 21% but less than 28% are typically labeled "slow burning". Any material with an LOI that exceeds 28% is classified as self-extinguishing.

In the table below, you'll find a list of polymers commonly found in our heat shrink tubing and braided sleeving products, along with their LOIs and the burn categories each falls into.


MATERIAL ALTERNATE NAME LOI CATEGORY
ECTFE (Ethylene chlorotrifluoroethylene) Halar 64% Self Extinguishing
Nomex N/A 28% Slow Burning
Nylon 6:6 N/A Ranges fron 24-29% Slow Burning to Self Extinguishing
PET (Polyethylene Terephthalate) Mylar (film), Dacron (fiber) Ranges from 21-34% Slow Burning to Self Extinguishing
Polyethylene (PE) N/A 17% Flammable
Polypropylene (PP) polythene (in the UK) 17% Flammable
Polytetrafluoroethylene (PTFE) Teflon 95% Self Extinguishing
Polyvinyl Chloride (PVC) N/A Ranges from 45-49% Self Extinguishing
