Specifi cations 8-2 How to Order 8.1 How to Order O-Rings and Other Parts 8.1.1 Parker Compound Numbering System From time to time, you will see Parker compound numbers shown in a three digit format without a zero (0) preceding the numerical designation. For example, compound N0674-70 may be shown as N674-70. The three digit format was previously used, but Parker has updated to the four digit format to allow utilization of a computer format for listing new compounds beyond 999. There is no difference in compounds shown with or without the zero (0) preceding the older three digit compound designations. The information in these tables may be used as a guide in selecting the most suitable Parker O-ring compound to seal any common fl uid, and in specifying the necessary size number for the desired dimensions. For further assistance, please feel free to call your Parker Seal Territory Sales Manager or Parker O-ring Distributor. You may also contact the Inside Sales Department at the Parker Seal O-ring Division, 2360 Palumbo Drive, P.O. Box 11751, Lexington, Kentucky 40512; telephone number (859) 269-2351. Parker compound numbers, with one notable exceptions, indicate the base polymer by a prefi x letter, and the type A durometer hardness by a two digit suffi x number. The basic number is merely a sequential number and has no particular signifi cance. In some instances, the prefi x letter is followed by a secondary letter. This indicates a specialty property. See the following examples: Example 1: N0674-70 indicates a 70 durometer nitrile compound durometer hardness base polymer Example 2: NA151-70 indicates a 70 durometer nitrile compound durometer hardness special property description Base Polymer Parker O-Ring Handbook Prefi x letters on compound designations used by Parker Seal, and the base polymers and specialty property description they indicate are identifi ed in Table 8-1a and 8-1b. Note that there is only one base polymer and one hardness associated with each basic number (i.e. there is not both N0674-70 and N0674-90).
