In hostile and corrosive environments, plastics can keep performing long after conventional materials would be destroyed. With lower friction and greater chemical compatibility than most metal alloys—not to mention a larger temperature range than standard elastomers—thermoplastic polymers can be engineered to excel under even the most punishing conditions.

Utex develops moldable thermoplastic polymers with a broad range of thermal and mechanical properties for some of the toughest applications, including the medical, aerospace, and petrochemical industries. Each of our highly engineered polymer components is carefully compounded and processed to possess the properties needed for the job at hand, allowing for optimum sealing performance in a wide variety of sealing environments.

With expert engineers and unsurpassed chemists, Utex is a leading specialist in providing plastic custom sealing solutions that solve the toughest design challenges while reducing the costs associated with metal components. Our polymer components offer:

Lightweight strength

Metal may be strong, but it comes at a heavy cost. For jobs that require strength without the extra weight, PEEK features incredible strength-to-weight ratios.

Low friction

When an application calls for minimal friction, thermoplastic polymers are often the answer. PTFE, for example, is ideal for low-friction jobs like sealing about a low torque shaft.

High temperature and chemical resistance

Corrosion is often a problem in demanding environments such as the oil and gas industry. Plastics can be engineered to withstand harsh chemical environments while operating under high temperatures and extreme pressure.

Enhanced properties

When their inherent performance characteristics aren’t enough, thermoplastic polymers can be enhanced with a variety of fillers such as glass, carbon, graphite, and molybdenum disulfide.


Plastics deliver exceptional wear under harsh conditions, extending operating life and providing an affordable alternative to conventional materials.

Precision machining

Thermoplastic polymers are highly susceptible to lathe cutting and milling. Our state-of-the-art machining produces exacting replication of critical dimensions, allowing us to meet even the most precise specifications. Our capabilities include:

  • Machining
  • Injection molding
  • Compression molding
  • Molding to metal or rubber

Our High Pressure / High Temperature revolutionary Spring Energized Seal designs and polymer components have the largest array of materials and spring designs in the industry.

We Utilized

PEEK Springs

PEEK Springs

Utex now has the ability to have PEEK springs in some applications instead of stainless steel. PEEK can reduce the wear and damage that occurs in dynamic applications and increasing the life of the seal. This increased lifespan reduces down time, adding value to any process.

We Created

Black Mamba Seal Stack

Black Mamba Seal Stack

Utilizing Utex’s black mamba energizer, seal stacks comprised of PTFE V-rings can stay energized to maintain good seal contact throughout multiple series of temperature and pressure cycling whereas standard seal stacks will take a set and loose energization. Black mamba seal sets are mostly used for sliding sleeve applications or as an alternative to a bonded seal.

Deep-Draw Backup Rings

Deep-Draw Backup Rings

When an application requires a backup ring capable of large burping pressure spike, e-gap must span a distance beyond what the standard 45 degree draw can accomplish. Utex is one of the first companies to offer a deep draw backup ring. Utex machines backup rings from PEEK, glass filled PEEK, carbon filled PEEK, and many other materials for sealing over precise and wide gaps.

We Accomplished

Case Study

Frac-Tex High Pressure Frac Ball Utex is able to produce composite frac balls that can be used in a wide range of fluids. These products are capable of landing on seat without damage at pressures of 10 ksi on six inch diameter balls and up to 15 ksi on smaller two inch units. Utex composite frac balls are machined using high grade materials and are held to strict quality control standards that diffuse many of the problems that arise with poorly manufactured frac balls. Utex provides its clients the flexibility to adapt to different well conditions by offering the composite line of frac balls in a number of variations. Such capabilities include custom size balls, resin systems, and fill materials.
