Valves, springs and fluid pressure push on the end plugs, eventually causing distortion and excessive clearance between the end plug and bore.
These Sonnax end plugs with O-rings restore hydraulic circuit integrity.
Sonnax O-ringed end plug kit 15741-36K will fit many of the 11mm diameter bores in the TF-80/81SC, TF-60SN and TR-60SN applications which have OE end plugs of similar configuration. The Sonnax end plugs feature an additional groove for the O-ring, but otherwise are similar to the OE end plugs in design and retention method. Compare your OE end plug to the photo above to see if the design is similar.
For 9mm diameter bores in listed applications, Sonnax offers 15741-35K.
