Our History

HiRel Connectors Inc. (HIRELCO) was founded in 1967 as a small business specializing in hermetic connectors primarily for military-based applications. Throughout the years, HIRELCO has evolved into an industry leader whose expertise is in designing and manufacturing custom and MIL-SPEC interconnect products for a variety of industries. Today, the HIRELCO group employs about 310 people among five facilities in the beautiful college towns of Claremont and Pomona, California. We proudly produce 100% of our parts right here in the United States. HIRELCO’s capabilities include designing, manufacturing and marketing electrical connectors, interconnect systems, specialty cables and connector accessories.

HIRELCO has been a trusted supplier in many industries since our inception. From providing the explosive bolts for the Apollo missions, to our most recent H2D High Density connectors for NASA’s ORION space program, we have been an integral part of mission-critical developments and successes. HIRELCO primarily focuses on providing solutions for existing problems within various markets when standard MIL-SPEC connectors and cable assemblies are just not robust enough to maintain performance.

In an effort to maintain component availability, controllability and simplicity, HIRELCO has implemented a vertically integrated supply system and thus, manufactures and performs most operations in house. Customized components and materials along with our design engineers, play a significant role in HIRELCO’s ability to produce the most reliable electrical connectors and cable assemblies in the world. Our company sets the precedence, as a diversified leader in high growth areas of the interconnect industry and provides creative solutions for our industrial, military and aerospace customers.

Our organization partners with other leading companies across a wide range of industrial applications and marketplaces. We develop products that sustain and enhance the performance of our customer’s critical programs and devices. HIRELCO’s successful expansion is a direct reflection of our entrepreneurial and agile engineering / management teams, as well as our entire company’s commitment to build the best electrical systems in the world.

For 50 years, HIRELCO has enjoyed tremendous success as the manufacturer of the most reliable connectors used in military applications, space and land-based programs, commercial aircraft and defense industries around the globe. As we continue to pave the way into the future, our mission is to continually develop the most reliable and trustworthy interconnect solutions. HIRELCO’s objective is to assist in achieving the goals and aspirations of our customers through reliability, innovation and technology for generations to come.
