Built on Precision. Proven by Performance.
Five decades of aerospace manufacturing — from a single grinding shop in 1968 to a premier supplier of flight safety-critical hardware for the world's leading rotorcraft and defense programs.
From Precision Grinding to Premier Aerospace Supplier.

TEK Precision Co., Ltd. was established in 1968 as a precision grinding company. Over the following decades, TEK expanded its infrastructure and quality management capabilities to serve the growing needs of the northeast regional OEM aerospace market.
By the early 1980s, TEK had evolved into a major hydraulic assembly supplier to Grumman Aerospace, delivering complex hydraulic actuation assemblies for F-14, A6, and E2-C weapons systems.
By 1982, TEK expanded once more into the rotorcraft market, manufacturing hydraulic valves and small assemblies for Sikorsky Aircraft. By the mid-1990s, the business focus shifted primarily to the production and aftermarket manufacturing of flight control and transmission components for rotorcraft platforms.
Today, TEK Precision is a premier supplier of world-class build-to-order products for Sikorsky Aircraft, the US Army, HSI, and Northrop Grumman.
