Parker O-Ring Sizing Gauges

sizing_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 base and a separate pi tape. The 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).
