a) Marine duplex oil strainer 25F -GP b) OD 25F GP (OD: symbol of marine duplex oil strainer, 25: nominal diameter, F:

material of body and O-ring, GP: the type using packing in the packing box) c) JIS F 7202 - 25F - GP

Example 2 For a strainer with a nominal diameter of 50, used for lubricating oil with a temperature of 100C or less and using O-ring in the packing box.

a) Marine duplex oil strainer 50M OR b) OD 50M OR (OD: symbol of marine duplex oil strainer, 50: nominal diameter, M:

material of body and O-ring, OR: the type using O-ring in the packing box) c) JIS F 7202 50M OR

9. Marking 9.1 Cover or strainer body The following particulars shall be marked on the surface of the cover or strainer body. (a) Nominal diameter Example: 50 (b) Kind of casting of O-ring and body (c) Manufacturers name or abbreviated trade name 9.2 Strainer body The following particulars shall be marked on the surface of strainer body. a) An arrowhead indicating the direction of flow at the inlet and outlet cock flanges or the surface of body b) Year of manufacture or symbol
