Sealol Mechanical Seals

Type YH670 is an all-Hastelloy C, rotating bellows seal, providing high strength and excellent corrosion resistance. It is extremely durable in seal applications where temperature and product concentrations result in an aggressive environment.
The Type YH670 has been tested per API-682 Type B seals for low-temperature refinery services. Other common applications include acids, caustics, amines, and products with H2S, such as sour water and sour hydrocarbons.
The Type YH670 can be designed as a dual seal using a non pressurized buffer or pressurized barrier fluid. A pumping ring recalculates barrier fluid, assuring cooler operating temperatures and extended reliable performance. For an additional lever of environmental and safety control, it can be combined with our YTS-1, which controls fugitive emissions.
