Turcon® Double Delta® II is a double-acting, O-ring energized dynamic seal made for MIL-G-5514F/MIL/AS568 grooves. Combining a precision Turcon® PTFE jacket with an elastomer energizer, it delivers low friction, stick‑slip‑free startup, excellent dry running, and adaptive contact force under pressure. It operates up to ~35 MPa, speeds ≤15 m/s, and temperatures from –45 °C to +200 °C. Ideal for light‑to‑medium hydraulic and pneumatic use. The O-Ring is not included with this item.
