Good To Know

Q: Can this filer set gaps on any piston ring? A: It is built for standard ring end gap work, but very large or unusual ring profiles may require a different grinding approach.

Q: Does it come ready to use? A: The unit is designed to be mounted or held on a bench while grinding, so keep the ring square to the wheel and check gap frequently.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
