Series 2209 low-pressure seals are designed for leak-tight sealing of flexible (non-armored) round cables with rubber and plastic insulation when they are led into machine (unit) housings.
Low-pressure seals are made of AISI 303 (12Kh18N10E) stainless steel. The following methods are used to ensure leak-tightness of a product:
- Product and machine (unit) housings are sealed using NPT thread
- Service fluid leakage from the machine (unit) along the external cable sheath is prevented by compressing a sealing bush located in an enclosed volume of a low-pressure sealing body. The sealing bush is placed between fluoroplastic washers to prevent its damage during compression.
Sealing bush material is fluorine rubber or silicon.
