Testing Capabilities

Utex manufacturing locations have testing capabilities, the equipment and processes vary depending on the overall product produced at each plant. The Utex Engineering group works with the various sites to facilitate the different tests that are requested or required by our customers. Qualification in accordance with API S64 can be conducted in house, depending on seal/system size. We also have relationships with labs and facilities to complete tests outside our current offerings.

Utex Mansfield, our metal machining facility, has three testing bays for pressure testing of metal components and assemblies. The parts or assemblies are leak tested using water and a computer-controlled process at high pressure (up to 22,500 PSI) to ensure they do not fail or leak while in use.

Utex Weimar has static pressure testing capabilities. Overall, we can test up to 15,000 PSI with a temperature range of -20°F to 350°F using nitrogen gas. Water can also be used as a media for testing but only at ambient temps.

Utex Conroe has static pressure testing capabilities up to 2,100 PSI at an ambient temperature with water or air.

Fluorescent Magnetic Particle Inspection (MPI) method uses a magnetic field to attract spray-on particles to a flux leakage that occurs in cracks in the material.

Ultrasonic Wall Thickness Testing (UTM) is used to measure the wall thickness of pipe and bores. It uses ultrasonic waves to measure the time it takes for a wave to pass through the material and return to the sensor. The time and type of material is used to determine the thickness of the material where measured.

A hardness digital tester can test the hardness of materials up to six-inch square coupons. It uses small anvils to indent the surface then measures the diameter of the dent and the force used to determine how hard the material is.


Factory acceptance testing (FAT) can be performed on site by request of our customers. Utex Engineering will work with our customers and third-party witnesses to verify that our products are complying to all parameters and meeting the application needs.

Material Testing

Utex has multiple labs to evaluate our custom materials. We test every batch of materials that are made and we develop new formulations based upon testing. Listed below are some of the various testing procedures we perform in our labs.

  • Tensile
  • Elongation
  • Tear Strength
  • Compression Set
  • Rheometry
  • Specific Gravity
  • Durometer
  • Oil Immersion
  • Abrasion
  • Peel (bond) Strength
In order to qualify our compounds to API and NORSOK, we also work with additional outside labs (**click link to see a list of qualified compounds)
