The KB14 seal is a special spring energised seals primarily intended for dynamic applications where reciprocating or moderate rotating movement is present. The P14 is used in applications where a standard cross section of seal cannot be used or where the seal requires an in-built stand-off ring to avoid crushing under potential back-pressure build up.

It can be used in applications where large gland tolerances exist or where there is a need for higher deflection due to expansion caused by high pressure duty. The seal is commonly used in foundries in place of standard rubber and fabric chevron seals where fluid compatibility is an issue or where extreme high temperature is present.

The seal consists of a U-shaped jacket and 2 cantilever springs which are available in 301 Stainless steel, Hastelloy® C-276 and Elgiloy® as standard. The cantilever spring design offers a moderate load versus deflection which is suitable for most applications. The design of the cantilever spring places the spring load at the front of the sealing lip making the KB14 seal an excellent option should a scraper lip be required for abrasive media sealing or scraping.
