Aerospace & Defence applications
Overview

What this sector demands

Harkesh Rubber is an ISO 9001:2015 certified manufacturer of precision-engineered rubber components for aerospace and defence programs, where reliability under extreme conditions is non-negotiable. Our elastomer parts are formulated and tested to withstand extreme temperature swings, high humidity, corrosive chemicals, UV and ozone exposure, and the pressures of high-altitude and vacuum environments. From custom diaphragms and O-rings to large structural components and precision plugs, every part is produced with tight tolerances and full material traceability to meet the strict demands of aerospace and defence customers.
