UPC seals machined from engineered plastics perform in low temperatures, valve applications, and critical environments. Our elastomeric seals are molded either stand-alone or to a metal alloy carrier.

Super Alloy

CNC machine

Our high performance machined metal seals are designed and manufactured from superalloys and coated for low leakage.  UPC seals outperform elastomeric seals whenever higher temperatures, aggressive environments or gland deflection are requirements.

Non-Metallic Seals

Complex Assembly

UPC integrates metals, composites, films, adhesives, rubber and additive materials through carefully manufactured and monitored processes for integration into critical systems.  UPC maintains strict oversight over all processes to achieve conformance and traceability required of aerospace quality systems.

  • Design, fabrication, assembly and test of seals, valves, burst discs and Belleville springs. Temperature, pressure, leakage, cycling, load & deflection testing onsite.
  • Analysis: Stress modeling: (FEA); Flow: (CFD)


burst discs 

Our high precision burst disc assembly is often mated to a relief valve to conserve system pressure after an over-pressurization event.

We provide both custom and standardized solutions for space projects, industrial, commercial aerospace, and transportation systems.
