Superior Terminals is the sole Australian agent for National Standard Parts Associates (NSPA), a Florida based manufacturer who was a pioneer of Heat Shrink Terminals. Heat shrink terminals sold by Superior: Carry Certification by Underwriters Laboratories (UL) Reference E157227 Carry US Military Specifications MIL-DTL-203050/4 Provide a positive join or termination by mechanical compression (crimp) of tinned copper or brass barrels and a chemical seal created by shrinkage/adhesive flow induced by heat application to the polyolefin tube. Prevent moisture wicking along wire and provide strain relief Are available in a diverse range of sizes and shapes. Are easy to use and are suitable for all stranded wire ranging from 8AWG (8.3mm²) down to 24AWG (0.2mm²). Heat shrink terminals in the past have often been inconsistent of quality, available in a very limited range and priced outrageously. These factors often precluded their use even in extreme conditions of moisture, temperature, pollution or vibration, leading to both wire degradation and terminal failure when cheaper automotive type terminals were used. The aim of Superior Terminals is to change that situation. We sell quality items directly to major users thereby eliminating supply chain imposts which inflate prices. This also allows us to focus on providing the highest level of customer service possible. Our product line consists solely of terminals, associated tools and a range of specialised heat shrink tubing. This enables us to carry a stock level of over 160,000 terminals covering over 60 individual lines including over a kilometer of 3M heat shrink tubing in various types. Stock levels are maintained by air from NSPA on a regular basis and items not normally stocked can be sourced from the US by expediated air freight in four to five days.
