FAQs

Oring gauges measure inside diameter, outside diameter, and cross-section thickness to match O-rings to specific applications.

Most oring gauges work with standard O-rings; some include additional scales for backup rings and specialty seals.

Place the O-ring on the gauge and align it with the closest size marking; verify both diameter and thickness dimensions.

Oring gauges help ensure correct seal sizes during fluid system repairs, reducing the risk of leaks and repeat service.

Stainless steel and aluminum oring gauges resist corrosion and maintain accuracy through repeated handling and cleaning.
