AS568-014 FFKM O-Ring — 12.42 × 1.78 mm
A compact, low-squeeze section for light-duty static and slow dynamic seals in smaller bore assemblies. With an inside diameter of 12.42 mm and a 1.78 mm cross section, this is a small-bore seal for compact assemblies and small-bore equipment. Moulded from Aperflu 2275 perfluoroelastomer (FFKM) for continuous service up to 200 °C, this seal resists hot acids, caustics, solvents, fuels and steam.

Metallurgy and steelmaking
Furnaces, casting lines, hydraulic systems and gas-supply equipment in hot, aggressive environments. Aperflu 2275 holds sealing force against heat, coolants and process gases where ordinary elastomers harden and crack.
Why Aperflu 2275 FFKM
The compound is moulded, de-flashed and inspected to a burr-free finish, and every batch ships with its own certificate of analysis for traceability.
Typical applications
Pneumatic fittings, low-pressure hydraulic circuits, valve stems and quick-connect couplings, where Aperflu 2275 outperforms FKM and EPDM in aggressive media and elevated temperature.
