As soon as the type of sealing is defined, one question arises: Is it a single acting sealing SE, meaning that it will ensure the sealing in one-sided, on the contrary with the double acting seal DE, this one may be subjected to the pressure from both sides.
It is strongly recommended to collect all the information needed for the proper functioning in order to define the most appropriated sealing solutions, and to understand the expectations of the user. This, in order to provide you the best advices.
Hardness: Qualifies the ability of the material to resist deformation under the pressure, hardness is expressed in Shore. Shore A for rubbers and Shore D for the thermoplastic material.
Pressure: Each kind of seal has unique characteristics resistant to the pressure, indicated for information, this remains subjected to the following criteria: conditions of use, operating pressure, permissible gap, operating speed, frequency, frictions and tolerance requirements in machining etc.
