National Standard Parts Associates, Inc (NSPA) recognized early on that electrical failures were major problems in the industry and that wire corrosion and wire pull-out were the two main causes of electrical failures. The Sealed Electrical System™ (SES) is the solution to this multi-billion dollar problem. NSPA started assembling our first crimp-style heat shrink connectors in the early 1980s. Today we are one of the leading manufacturers of sealed, heat-shrink connectors and terminals. After 40 years, our motto has stayed the same, “Do It Once, Do It Right!” NSPA is a family-owned business that still operates today using traditional values and understands the importance of honesty, integrity, and building strategic alliances with its customers.
