Our replacement parts and repairs give you the long-term reliability you need.make the most of your investments in testing equipment. That way, you get the results you need and the value you deserve.

For your convenience, we’ve provided a cutaway view of a WEBSTER® product that shows the working parts common to all quality control testers. Each is easily identified with a model and serial number stamped on the frame, which should help you communicate effectively you need when ordering parts or requesting service. For best performance, make sure to examine penetrators periodically for wear and replace them promptly when they show signs of distress. These devices and load springs differ with each tester model. The other parts on the diagram are common to all three devices we service.
