Multiple spring seals

UK Seals supply a range of balanced and unbalanced multiple spring seals that are ideal for corrosive and demanding applications.

Multiple spring seals are designed so that an even face load is applied over the face area but a number of compression springs. This results in higher pressure sealing capabilities.

Multiple spring mechanical seals are available as internal component and external Cartridge Seals, as standard with 316SS and triple phenolic carbon.
