Oil and gas operations place extreme demands on sealing materials and components. Equipment used in drilling, production, transportation, and refining must withstand pressure changes, aggressive chemicals, temperature swings, and continuous exposure to hydrocarbons. Pneu-Draulics Inc. supplies engineered sealing solutions designed for these operating conditions, supporting upstream, midstream, and downstream applications with reliable products, technical guidance, and responsive service.

Our capabilities include high-pressure high-temperature (HPHT) seals, rapid gas decompression (RGD) seals, API-compliant sealing components, and custom O-ring solutions for critical oilfield equipment. We also provide custom kitting, packaging, and inventory support to help OEMs, MRO teams, and industrial procurement professionals manage demanding maintenance schedules and production timelines.

Our High-Pressure, High-Temperature (HPHT) Sealing Solutions

Oilfield sealing systems are regularly exposed to pressure fluctuations that can damage standard elastomers. In gas service applications, trapped gases may expand rapidly inside the seal material during decompression, leading to cracks, blisters, or seal failure. To address these conditions, Pneu-Draulics supplies explosive decompression-resistant seals engineered for rapid gas decompression (RGD) performance.

Our sealing materials are selected to meet the requirements commonly associated with offshore drilling and high-pressure applications, including NACE TM0297, NORSOK M-710, and ISO 23936-2 standards for chemical compatibility and hydrocarbon resistance. We also support customers requiring API 6A and 16A compliant seals for wellhead equipment, blowout preventers, and related oilfield systems.

With two warehouse locations positioned to support Gulf Coast operations and nationwide shipping capabilities, we help customers reduce downtime and maintain access to critical sealing components for both scheduled maintenance and emergency replacement needs.

Advanced Materials: HNBR, FKM, and FFKM for Harsh Environments

Material selection plays a major role in long-term sealing performance in oil and gas systems. Pneu-Draulics supplies several oil and gas O-ring material options commonly specified for demanding industrial environments:

  • HNBR (Hydrogenated Nitrile Butadiene Rubber) is widely used in downhole sealing solutions because of its resistance to heat, sour gas exposure, oils, and steam. It is commonly selected for HPHT and RGD applications.
  • FKM (Fluoroelastomer) provides strong resistance to fuels, oils, aromatic hydrocarbons, and many aggressive chemicals. These materials are often used in refinery systems, valves, and petrochemical processing equipment.
  • FFKM (Perfluoroelastomer) is designed for the harshest operating environments, including subsea systems, high-acid gas exposure, and applications involving elevated temperatures and aggressive chemicals.

Many of our compounds are available in formulations tested for RGD resistance and long-term chemical compatibility in oilfield environments.

Our Design, Manufacturing, Kitting, and Packaging Capabilities

Since 1982, Pneu-Draulics has supported industrial customers with sealing products manufactured and distributed from the United States. In addition to supplying standard O-rings and sealing products, we assist customers with material selection, seal profile development, groove design considerations, and custom-engineered sealing solutions.

We also provide value-added services that help simplify procurement and maintenance operations, including:

  • Custom seal kitting for MRO operations and field service teams
  • Packaging and labeling based on customer part numbering systems
  • Support for non-standard seal profiles and specialized applications
  • Inventory management assistance for recurring maintenance programs

As an ISO 9001:2015 certified supplier and authorized Parker Hannifin Seal Group and Hallite distributor, we maintain traceability and quality documentation required by many industrial and energy sector customers.

Upstream, Midstream, and Downstream Sealing Applications

Our sealing products support a wide range of oil and gas applications across all stages of production and processing.

In upstream operations, high-pressure seals are used in mud motors, production packers, wellhead assemblies, and other drilling equipment exposed to severe pressure and temperature conditions. RGD-resistant materials are especially important where rapid decompression can damage conventional seals.

Midstream systems rely on sealing components for compressors, valves, pumps, and pipeline infrastructure operating across changing environmental conditions and fluctuating temperatures.

In downstream refining and petrochemical processing, FKM and FFKM materials are commonly used in heat exchangers, pumps, and chemical handling systems where aggressive media and thermal cycling can shorten seal life.

Pneu-Draulics supports both OEM production requirements and ongoing MRO programs with standard catalog products as well as custom-engineered sealing solutions.
