Who We Are

Improving the quality of automotive, industrial and aerospace parts since 1966, QSR is a global leader in custom molded, precision rubber components.

Strengthened by a merger with Lexington Rubber in 2012, QSR’s skilled workforce offers customers a unique combination of technical expertise, advanced manufacturing practices and something seldom available from rubber companies—product development.

Engineers know they can rely on QSR’s engineering, research, development and technical expertise to meet all their needs for products requiring a high level of engineering due to material properties, temperature requirements and tight tolerances. In fact, the majority of insulator and connector seal material for products QSR manufactures is internally compounded from proprietary formulations.

QSR principal product lines include:

  • Connector seals used in electrical connectors and wire harnesses to protect connections from harmful elements like oil, water, salt and dust
  • Insulators for automotive ignition systems to seal and insulate terminals on the spark plug and distributor

QSR is a division of Q Holding Company, which is owned by 3i, a leading international investment manager focused on mid-market private equity, infrastructure and debt management across Europe, Asia and North America. For further information about 3i, please visit: www.3i.com.
