High Pressure - Installation of the Spark Plug 794 055A
- The numeric and alphanumeric code '794 00055a' is not arbitrary; it signifies specific attributes and specifications of the spark plug. The '794%' could denote the model series or a particular performance rating, while the '2000055a' might refer to the unique identification number or the manufacturing details. It's essential to note that manufacturers often use such codes to differentiate their products and highlight their distinctive features.
Table 2 a): Common types of oil seals (with spring)
To increase the pressure around the shaft and maintain the seal’s integrity, certain lip seals have an extra spring looped into the flexible rubber part.
NBR rubber is above all resistant to oils, especially hydraulic oils, lubricants, petrol and other aliphatic hydrocarbons, diluted acids and lyes. Good physical values such as high friction resistance and ruggedness and good temperature resistance (-25 °C up to +120 °C, in part to -40 °C) give this natural rubber a wide range of uses.

ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.
