Chemical Processing Applications and Solutions
Seals, structural components, wear parts—Greene Tweed improves performance in your industrial applications. Market leading OEMs around the world trust our expertise when it comes to reliable and durable products.
Years of technical experience and innovation
For more than 150 years, customers have relied on Greene Tweed to increase meantime between repair (MTBR) and increase operational safety and environmental compliance.
Our seals, engineered components, and thermoplastic composite wear parts deliver proven performance in aggressive media such as hydrocarbons and aromatics, ethylene oxide, inorganic bases, solvents, steam, oxidizing acids, alcohols, sour gases, and amines. Our solutions are found in equipment commonly used in chemical processing including compressors, pumps, mixers, centrifuges, filtration systems, instrumentation, mechanical seals, and valves.
Expert Application Engineering
A Greene Tweed seal in a centrifugal compressor can help increase reliability and efficiency. Our portfolio includes a variety of geometries, including MSE® lip seals, labyrinth seals, and o-rings. Through careful material selection, seals are optimized for chemical resistance and temperature to minimize the likelihood of unplanned downtime. Our elastomer portfolio includes grades of Chemraz® FFKM and Fusion® FKM qualified for rapid gas decompression (RGD) under the ISO 23936-2 testing standard.
Sealing Solutions for Harsh Chemicals
Aggressive solvents damage traditional solutions and risk premature failure. Optimize performance with our Chemraz® perfluoroelastomers and Arlon® PEEK thermoplastics. They offer near total protection against chemical attack. Even in extreme temperatures and harsh environments.
Pumps, Cylinder Seals, Wear Rings
Greene Tweed manufactures seals from proprietary elastomeric and thermoplastic materials in designs ranging from standard O-rings to custom-engineered seal stacks for complex applications. We primarily offer five core types of seals for the chemical industry: O-rings, G-T® rings, MSE® seals, seal stacks, and capped seals. And for niche applications, we’ll work with you to design a custom-engineered sealing solution tailored to your needs.
Pumps & Valves
Greene Tweed pump components are made from our high-performance thermoplastic composite materials for centrifugal pumps and seal-less (magnetic drive and canned motor) pumps. They are used in chemical plants, refineries, petrochemical plants, and power generation plants worldwide.
Our valve components, backed by more than 30 years of design experience, reduce leakage and fugitive emissions to optimize performance in valves, taking media, temperature, and pressure – among other factors – into consideration.

Custom Engineered Sealing Solutions
The most common type of elastomer seal, o-rings provide cost-effective, flexible sealing solutions across a wide range of demanding applications. The o-ring can be used either as a seal itself or as the energizing element in PTFE, cap-type seals.
If you are looking for backup rings, Greene Tweed’s engineers will work with you to develop a custom designed backup ring configuration suited to your needs.
Versatile Sealing for Demanding Environments
Metal spring energized (MSE®) seals are custom designed with a dual-lip body for superior performance in the most demanding conditions. They are built to withstand extreme temperatures, high pressure, and corrosive chemicals found in a aerospace, energy, and other industrial applications.
Greene Tweed’s selection of MSE® seals are custom engineered to be used across a wide range of industries and applications. No matter how demanding the environment, our team works with you to determine the right sealing solution.
Avoid Damage and Downtime
Greene Tweed thermoplastic composite wear parts are designed to enhance the safety and efficiency of your operations. Lighter and more resistant than their metal counterparts, our engineered components have become the industry standard for refineries, chemical plants, and power generation plants.
- Reduced repair and maintenance time
- Minimized chance of damage to critical components
- Reduced vibration due to tighter clearance
Reliable Connections in Rugged Environments
Greene Tweed Seal-Connect® electrical and fiber optic connectivity solutions can withstand extreme temperatures, vibration, and shock. We developed our connector portfolio over decades of collaboration with equipment manufacturers, service providers, and operators, leading to over 80 U.S. and foreign patents. On land or offshore, our engineers work with you to determine the best solution for your application.
