FGS-Micro Mini O-rings

Precision Micro & Micro-Miniature O-Rings and Molded Components

Precision Sealing Solutions For The Most Demanding Applications

Crafted for Precision. Built for Trust.

At Finn Global Supply, we engineer micro O-rings, micro-miniature O-rings, and molded rubber components that deliver the high-performance sealing solutions today’s industries demand — ensuring accuracy, consistency, and reliability from prototype to production.

What sets our micro-miniature components apart:

  • Unmatched precision — Tight tolerances and controlled molding processes ensure repeatable quality.
  • Versatile materials — Wide selection of high-performance elastomers for varied applications.
  • Rapid prototyping — From concept to production, we move fast without compromising accuracy.
  • Reliable sealing — Proven performance in medical, electronic, and fluid-control systems.
FGS-Micro Mini O-rings

Our micro and micro-miniature O-rings are trusted across industries where precision and reliability are non-negotiable. From medical devices that demand biocompatibility and consistent sealing, to semiconductor equipment operating in extreme conditions, these components are engineered to perform where larger seals can’t.

As devices and mechanical systems continue to shrink in size, the demand for miniaturized sealing solutions continues to grow — and Finn Global Supply leads the way with innovation, expertise, and unwavering quality.

Common applications include:
  • Medical and diagnostic devices — ensuring leak-free performance in compact instruments.
  • Semiconductor and electronics — maintaining vacuum integrity and contamination control.
  • Fluid and gas systems — providing reliable micro-sealing for valves, sensors, and fittings.
  • Aerospace and defense — offering stability under pressure, temperature, and vibration.

Each micro-molded component is manufactured under strict quality control to guarantee dimensional accuracy, surface finish, and long-term durability — meeting the highest standards for performance and consistency.
