Accu Shot O‑Rings — Zero Drag. Pure Valve Speed.

No Silicone. No Stick. No Dry‑Wiper Drag. These are the O‑rings built for tuners who know exactly what silicone does to an Impact M4 cycle — slows it down, grabs the rod, and kills consistency. Accu Shot’s non‑silicone blend eliminates that sticky, dry‑wipe resistance and lets the valve move the way FX intended: fast, clean, and repeatable.

Key Features

• No silicone rubber — no tack, no stiction, no “dry windshield wiper” drag on the valve rod during the cycle.

• Faster valve snap‑back for tighter ES and more predictable dwell behavior.

• Low‑friction material blend that won’t grab, swell, or soften under pressure.

• Stable geometry across temperature swings — no gummy feel, no sluggish cycling.

• Improves shot‑to‑shot consistency by letting the valve move freely and cleanly.

• Drop‑in upgrade for all FX Impact M4 valve rod assemblies.

• Built for tuners chasing crisp, efficient air release and repeatable performance.

• Accu Shot Orings — When Consistency Counts.
