G1025 Bushing O-Ring
This quad ring is used in the H series dowel inserter driver assemblies. Two of these are needed to repair an air leak coming from the front of the drive. This is the most common air leak on an HPJ or H-49 machine. Remember to grease them liberally on reassembly. Disassembly of the whole driver is not necessary. Remove the bronze bushing gently and fish the old bushings out. A little air presser on the return side can encourage them to come out.
