For engineers battling space constraints in hydraulic and fluid power systems, the T-Seal Compact Seal delivers unparalleled stability and pressure resistance while fitting standard O-ring grooves. T-Seals are mostly used in stab and static applications,used for many oil and gas applications in wellhead equipment, downhole and surface applications. The T Seal has an elastomer T-shaped crossed sect...
EWT series Hammer Union Seals are static seals, which are used in hammer union-style pipe connections to establish flow lines and prevent leakage. JST provides a number of compounds compatible with mud, crude oil and chemicals with acid or H2S. JST offers two lines of hammer union seals, one from elastomer, another one from elastomer reinforced with anti extrusion ring which is normally used for h...
EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals. Its main function is to prevent plungers from leakage in high-speed reciprocating. Some special working conditions are taken into consideration when designing its structure and material, which make it apply to fracturing fluid, mud so on mediums. Technical Requirements...
In the intricate world of medical devices and equipment, where precision, sterility, and reliability are non-negotiable, seemingly small components play outsized roles. Among these unsung heroes are gaskets and seals. And when it comes to choosing the right material for these critical interfaces in medical applications, EPDM (Ethylene Propylene Diene Monomer) consistently emerges as a champion. Le...
The extreme conditions of downhole oil and gas operations demand sealing solutions that defy pressure, temperature, and aggressive media. HNBR S-Seals have emerged as a critical defense line for drilling tools, completion equipment, and production systems, offering a balance of resilience, cost-effectiveness, and performance where failure is not an option. Conquering Downhole Extremes with Materia...
Finite element analysis (FEA) is the process of predicting an object’s behavior based on calculations made with the finite element method (FEM). While FEM is a mathematical technique, FEA is the interpretation of the results FEM provides. FEA gives engineers insights into complex systems and structures, helping them make more informed design decisions. FEM uses math to break complex systems into s...
The semiconductor industry demands precision, reliability, and contamination-free environments to ensure flawless production processes. At the heart of this mission lie specialized sealing solutions capable of withstanding extreme conditions. FFKM (Perfluoroelastomer) O-rings have emerged as the gold standard for critical applications in semiconductor manufacturing, offering unparalleled resistanc...
In oil and gas wells (and sometimes geothermal wells), a wiper plug is a device used mainly during cementing operations. Its job is to separate drilling mud and cement slurry, wipe the casing clean, and ensure that fluids don't contaminate each other. The seal part of the wiper plug is critical — it makes sure: The mud and cement stay separated properly, The pressure holds up during the pump-down ...
In the demanding environments of oil and gas, casing, and hydraulic systems, reliable sealing is critical to prevent leaks, reduce downtime, and ensure operational safety. Designed to handle both internal and external pressure, S-Seals offer superior performance compared to traditional O-rings, especially in dynamic applications. What Is an S-Seal? The S-Seal is a speciali...
