The "PST service" catalogue contains the majority of sizes of the oil seals necessary for repair of systems of the power steering for modern cars as well as for the cars, which are out of production.

The catalog is summary and includes quality products of various global manufacturers.

It was taken into account, at drafting of this catalogue, that some oil seals with identical dimensions and properties, applied to repair of power steering units, are interchangeable, though they have some differences in a design. The majority of similar oil seals have been united to one catalogue number and to one type. This allowed to avoid creation of duplicates (equal oil seals with different catalogue numbers), thus, the catalogue and the prices have been maximal optimized.

It means that for one code from the PST service catalogue may accord several oil seals with identical dimensions and properties, but with different design.

The differences in design of oil seals don't influence on their working properties and applicability. 

Example:

The classical high pressure oil seal (without additional protection against dirt/dust) in PST oil seals catalogue has S-HP/HPs designation. All types (1, 2, 3), shown below, correspond with S-HP/HPs designation.

 1. Without plastic inset. (it can be applied without any restrictions).

2. With open plastic inset. (in certain cases an additional external plastic or metal supporting spacer may be required).


3. With closed plastic inset. (it can be applied without any restrictions. in catalogue may be marked with index "A". f.e. SPS0000A).


4. The extention type of inset. (it can be applied without any restrictions. in catalogue may be marked with index "C". f.e. SPS0000C).

In the catalogue of oil seals for power steering of PST service s.r.o., all oil seals with equal dimensions and construction’s type (see samples 1,2,3,4 above) are joint to one catalogue’s code (f.e. SPS0000). Also those oil seals may be separate out with alphabetic notation (f.e.”A” or ”C”) at the end of catalogues code (f.e. SPS0000A; SPS0000C, please see description above).
