Back-Up Rings 6-4 Parker Parbak 8-Series Dimensions W Parker O-Ring Handbook T Ref. A Parker Parbaks were developed primarily for service in petroleum based hydraulic fl uids, at -4°C to 121°C (-40°F to 250°F). Parker’s standard Parbak compound N1444-90, provides the maximum benefi ts in back-up ring service. Compounds for use in other fl uids and for temperatures up to 204°C (400°F) are available upon request. Parker Parbak 8-Series Dimensions Dash I.D. Tol. R T A Tol. W Tol. No. (in.) ± ±.010 (Ref.)

Max. Section W-W Notes: 1. Parbak sizes are designed to correspond with the Parker 2-xxx, 3-xxx and AS568A series O-ring with which they are used. 2. Complete call-out consists of the digit 8, the dash number for the size wanted and the rubber material. Example: N1444-90 8-009. Table 6-1: Parker Parbak 8-Series Dimensions I.D. Parbaks will stretch up to 50%, and are quickly and easily installed. Advantages of the contour design are obtained regardless of how Parbaks are installed — they may be installed with the concave face in either direction, toward or away from the O-ring. Dash I.D. Tol.
