RediVac® means ready for vacuum service, now.

The UC Components, Inc. proprietary RediVac® system ensures that every fastener and seal you order from us arrives ready to install immediately – saving you time, effort, and money.

The proper handling of hardware and fasteners for your vacuum applications cannot be taken lightly. The value of a cleaned & vacuum-baked O-Ring and a properly vented screw, nut, or washer may seem trivial but their overall performance and savings for you (both in cost and time) can be measured.

UC Components performs rigorous testing quantifying the value added benefits of vented hardware and the use of our O-Rings. Through Residual Gas Analysis (RGA) and computerized pump curve plotting with fixed volumes, clean vented hardware and proper seals have demonstrated a major reduction in pre-process vacuum conditioning.

How does our RediVac® process benefit you and your system?

  • Faster pump-down via greatly reduced surface H2O
  • Enhanced process reliability via greatly reduced hydrocarbon contamination
  • Improved traceability via available full certification with RGA graph
  • Certified Class 100 packaging with nitrogen purge & vacuum seal
  • Cleaning, baking, & packaging performed in ISO Class 5 Cleanroom
  • Seven standard RediVac® finishes available with Vacuum Bake finish: Ag, Au, ENP (Ni), MoS2, WS2, EP, & Precision Cleaned
  • Fasteners available in stainless steel and other base materials, metric, & inch
  • Fasteners available in vented, non-vented, & custom configurations
  • Color-coded labeling system for easy identification

How does the process work?
This proprietary process reduces surface particulates and other contamination by utilizing a multi-stage cleaning, inspecting, and packaging process which is all done inside of our top-of-the-line certified Class 100/ISO Class 5 Cleanroom. 
Step 1: Ultrasonic cleaning process
Step 2: Close inspection
Step 3: State-of-the-art vacuum packaging

By reducing additional vacuum preparation steps, our RediVac® products help you run faster and leaner.
