K38 is a single acting rod seal designed to have inner lip shorterthan the outer lip and additional sealing lip which improves theleakage behavior and , at the same time , prevents the entry ofcontaminations from the wiper side.

PRODUCT ADVANTAGES
• Superior sealing effect with the secondary lip
• Low axial housing heights
• Secondary sealing lip provides extra protection against theingress of dirt particles
• Easy assembly into closed grooves
• Good sealing performance even at low pressures
• Wide range of dimensions

APPLICATION
Construction machinery , fork-lift trucks , injection mouldingmachines , agricultural machinery , mobile hydraulics , standardcylinders , loading platforms and telescopic 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. Before installation the sealing element must be oiled with system oil.

MINUMUM DIAMETER VALUES FOR CLOSED TYPE OF GROOVES
(D-d)/2 (mm)	4	5	6	7.7	10	12.5	15
dmin (mm)	25	30	40	50	80	100	105

NOTES
The permissible sealing gap values of K38 rod seal is givenin the below table.

PERMISSIBLE SEALING GAP
	Smax (mm)
t=(D-d)/2(mm)	150 Bar	250 Bar	400 Bar
t≤5	0.30	0.20	0.15
t>5	0.35	0.25	0.20

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.
