North America’s leading manufacturer
of sealed electrical connectors!
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 1980’s. Today we are one of the leading manufacturers of sealed, heat shrink connectors and terminals. After 30 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.

Equipment downtime often results in hundreds to thousands of dollars in lost opportunities and repair costs. Read More ...
