The AS568 dash -112 is a high-frequency inquiry size in the 2.62 mm cross-section family. Below are its dimensions, the compounds we can source, and how to order a small batch or a single sample through our coordination.
AS568 uses a "dash" number to define inner diameter × cross-section. The -112 sits in the 2.62 mm cross-section series (Series 100) — distinct from the -014 which uses 1.78 mm. Always confirm the actual measured size against your groove.
| Attribute | Value |
|---|---|
| Dash number | -112 (often written 2-112) |
| Cross-section (wire diameter) | 2.62 mm (0.103 in) |
| Nominal inner diameter | 12.37 mm (0.487 in) |
| Outside diameter | 17.60 mm (0.693 in) |
| Standard family | AS568 (Series 100, US Aerospace Size Standard 568) |
O-rings are light — air freight is typically a few USD per parcel, so freight stays well below part value even for small batches.
Where a 2-112 O-ring is commonly specified:
AS568 dash -112 has a nominal inner diameter of 12.37 mm (0.487 in), a cross-section of 2.62 mm (0.103 in) and an outside diameter of 17.60 mm (0.693 in). It belongs to the 2.62 mm cross-section (Series 100) family.
We source NBR (general duty), FKM (chemical / higher temperature) and FFKM / Kalrez-type (extreme chemical & temperature, semiconductor & pharma) equivalents via coordination. Confirm media and temperature before selecting the compound.
Yes. Small quantities and 1-pc samples are part of our long-tail rubber lane. O-rings are light, so air freight cost stays low (typically a few USD per parcel) — freight stays well below part value. Samples are quoted at sample price; freight is on the customer.
