K23 is a single acting piston seal designed to have outer lip shorter than the inner lip in order to be used for piston applications.
PRODUCT ADVANTAGES • Superior static and dynamic sealing effect • Wide range of dimensions • Easy assembly into closed grooves • Simple groove design • Economical sealing solution
APPLICATION Construction machinery , fork-lift trucks , injection moulding machines , agricultural machinery , loading platforms and standard cylinders.

Note: It is recommended to have 50% to 90% of the working surface material contact area value.
INSTALLATION Easily assembled into closed grooves according to the minimum diameter values that are given in the below table. Open grooves or special assembly tools should be used for the values that are outside this table. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
MINUMUM DIAMETER VALUES FOR CLOSED TYPE OF GROOVES
NOTES For special applications that require high temperatures , K23 can be produced in FKM material. The permissible sealing gap values of K23 piston seal is given in the below table.

Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
