Typically used for medium voltage electric motors, Nomex Slot Wedges are a mainstay of the electric motor rewinding industry. Like so many other electrical insulation parts, these preformed wedges go by many names, including: Nomex Slot Sticks & Nomex Wedges.

Manufactured from DuPont Nomex Paper, our Nomex Slot Wedges have good mechanical attributes, a high temperature rating and are available in a large range of sizes.

All our Nomex wedges are made from 100% genuine DuPont Nomex. They are pressure-formed to shape so that they retain their form without exhibiting any of Nomex’s usual tendency to “spring-back”.

We are pleased to stock these slot sticks in both curved and squared styles. This page contains all the information on the Square style. The round Nomex Slot Wedges are also available.

The size table below lists the dimensions for all the sizes that make up our standard, stocked range. Each is supplied in a pack consisting of 250 feet worth of 36 inch long slot wedges.
