Perma-Seal™ Terminals

Terminals and splices from Molex provide a rugged, environmentally-sealed connection to withstand water, salt, condensation, corrosion, and heat

Perma-Seal™ TerminalsMolex Perma-Seal terminals and splices provide a rugged environmentally sealed connection for wire sizes 8 to 22 AWG. Perma-Seal insulates, protects and seals electrical connections from physical abuse, abrasion, water, salt and other corrosive compounds.

Perma-Seal terminals and splices give you long-lasting, moisture-proof connections that withstand water, salt, condensation, corrosion and heat, all of which cause serious problems for conventional, unsealed splices. The inner wall of the heat-shrinkable Perma-Seal sleeve is lined with a special hot-melt adhesive that is inert at room temperature, permitting wires to be inserted easily into the splices and terminals. As the sleeve is heated, the adhesive melts and flows under pressure from the tubing. This action fills any existing voids and creates a seal that repels moisture incursion, even during pressure cycling, and stands up to some of the most rigorous tests that can be applied to high-performance splices, such as the salt fog test MIL-T-7928.

The tough sleeve of Perma-Seal splices and terminals resists abrasion and cutting. This protection helps to maintain the insulation and sealing properties even in the most hostile environments, inside and out.


  • Wall thickness is significantly thicker than competing polyolefin or nylon products, providing excellent durability
  • Shrinks fast — up to 40% faster than polyolefin or nylon products saving installation costs and dramatically reducing the potential for wire insulation damage
  • Insulation made of high-performance NiAc third-generation material
  • Excellent chemical resistant properties. Perma-Seal will keep on working even when immersed in the following chemicals: Antifreeze, brake fluid, gasoline, motor oil, isopropanol, trichloroethylene, diesel fuel, salt water, and battery acid
