Parker O-Ring Sizing Gauges

O-Rings for Gauges Sizing Device

gauge-coneThe Parker Size Gauge for O-Rings is an exclusive Parker Seal Group device consisting of a uniquely marked plastic cone with special Cross-section measuring the base and a separate pi tape. The Parker O-Rings for gauges sizing device is used for checking any sample O-Ring up to eight (8.00″) inches in diameter to determine the nearest standard Parker Seal 2-dash size (corresponding to ARP568A standard series O-Rings).

NOTE: The device does not measure actual dimensions. Proper identification and markings appear on the cone and tape, making the device easy to read. The cone and tape are sold as a set.
