This specification sheet establishes requirements for high collapse pressure configuration filter elements of several configurations with a minimum filtration ratio of 75 for particles larger than 10 ?m when designed and tested in accordance with SAE J2321 and this specification sheet. Part or Identifying Number??Filter elements can be identified and ordered using part identifying numbers as follows: EXAMPLE??J2321/3?CC10?CF is for a configuration C element with filtration ratio >75 for particles larger than 10 ?m(c) with a fluorocarbon O-ring. FILTER ELEMENT SIZE AND CONFIGURATION??The following sizes and corresponding configurations are covered: A = Figure 1 Configuration C = Figure 2 Configuration D = Figure 3 Configuration FILTRATION RATIO??(Currently only the following rating is covered.) 10 = Minimum Filtration Ratio of 75 for particles greater than 10 ?m(c)SEAL MATERIAL??The O-ring to be supplied with the C Size element shall be of the size specified in 3.13 and with material as designated as follows: No designation = Supplied without O-ring F = Fluorocarbon rubber per SAE AS3209-132 N = Nitrile rubber per AMS-P-83461/1-132 X = Seal material as designated by purchaser?Rationale??This document has been reaffirmed to comply with the SAE 5-Year Review policy.?
