Common sense about the sealing ring of cartridge
Usually the seal ring used on the filter is generally O-type sealing ring, generally used nitrile rubber, nr, neoprene, ethylene-propylene rubber, fluorine rubber, silicone rubber and mixed plastic manufacturing. In addition to the O-type, there are triangular, rectangular, D, t, Square, Heart, X, five-sided, olive-type.
O-Type sealing ring: Mainly used for static seals and reciprocating movement seals. For rotating motion seals, it is limited to low-speed rotary seals.
Product use: The standard O-type rubber seal ring is suitable for hydraulic pneumatic system and all kinds of mechanical equipment and components, in the specified pressure, temperature and different liquid and gas medium, in the static or moving state of sealing role. Working temperature: -40~+230℃ Working pressure: <10~220kg, f/cm.
Working medium: Air, water, oil product hardness: 40~85±2a material: nitrile rubber, silica gel, fluorine gum, ethylene propylene
Product use: This standard applies to the oil cylinder pressure is greater than 10MPa with the O-ring use. Operating Temperature:-100~200℃
Working medium: Hydraulic oil, emulsion, water material: PTFE According to: jb/zq4224-86 Suitable for gb1235-76
