Collection: About Us


Founded in 1992, NDT Seals, Inc. is a family-owned and managed business in Houston, Texas. We design, manufacture and distribute the patented NDT Inspection Plug and NDT Inspection Point Labels.

These products are used in the Process Safety Management and Mechanical Integrity efforts underway in the refining, chemical, petrochemical, paper and pulp, household products, food processing, and transportation industries. 

An ISO:9001:2015 certified business, our products are designed to identify and access Thickness Measurement Locations (TML's) on insulated and non-insulated pipe and equipment to monitor structural integrity. This site is our opportunity to introduce you to our products, the federal regulations and industry codes that are defining these efforts, and to help you connect to the business and professional organizations, events and resources that support this process.
