STAMFORD, Connecticut, June 30, 2026
Gainline Capital Partners has announced that its portfolio company M&M International, a leading manufacturer of precision-engineered stainless-steel tubing for the medical device industry, has completed the acquisition of KC Tech. The strategic transaction marks another milestone in M&M International’s multi-year growth strategy, strengthening its manufacturing capabilities and expanding its portfolio of medical-grade tubing solutions for global medical device manufacturers. By integrating KC Tech’s complementary expertise in larger-diameter precision tubing, the acquisition enhances M&M’s ability to deliver high-performance components for increasingly complex medical technologies. The deal reflects the growing demand for advanced manufacturing capabilities within the healthcare sector, where precision-engineered tubing plays a critical role in minimally invasive devices, interventional systems, diagnostic instruments, and other life science applications. With both companies bringing decades of manufacturing expertise and long-standing collaboration, the acquisition is expected to accelerate innovation, improve production capacity, and strengthen supply chain support for medical device customers worldwide.
Strategic Acquisition Expands Medical-Grade Tubing Portfolio
The acquisition significantly broadens M&M International’s manufacturing capabilities by adding KC Tech’s specialized large-diameter stainless-steel tubing technologies to its existing portfolio of small-diameter precision tubing products. The combined capabilities enable the company to offer a more comprehensive range of solutions for medical device manufacturers requiring highly engineered metal tubing with exceptional dimensional accuracy, material quality, and manufacturing consistency. According to M&M leadership, the transaction builds upon more than a decade of collaboration between the two organizations, creating a seamless integration of manufacturing expertise, technical knowledge, and skilled personnel.
By combining complementary production capabilities under one organization, M&M will be better positioned to meet the evolving needs of customers developing next-generation medical technologies. The expanded product portfolio is expected to support growing demand for precision tubing used in catheters, minimally invasive surgical devices, diagnostic systems, cardiovascular technologies, and other high-performance medical applications, reinforcing the company’s position within the global medical device supply chain.
