APG Measuring Cone, Large, For Use With: 5-5/8 in ID O-Rings
Unique device for measuring O-rings up to 5-5/8 in ID. The base of the cone is used to determine the cross-section of the O-ring. Then, for O-rings 1/4 to 3 in ID, the ring is simply dropped over the cone and the size is read above the O-ring. For O-rings from 3 to 8 in ID, the tape is simply expanded inside the O-ring and the size is read directly from the tape. All size numbers correspond to industry ARP standard size series.
