Genuine Vorsk 1911 gas input valve
The gas input valve, more commonly called the fill valve, is the small one-way valve on the base of your magazine. It lets gas flow into the reservoir when you charge the mag, then seals tight to keep that gas under pressure until you shoot. It is a critical part, and when it fails your magazine simply stops working. This is the genuine Vorsk 1911 replacement.
What it fixes
A failed input valve shows itself in a few clear ways: the magazine will not take gas at all, it spits gas back at you as you try to fill it, or it charges but then leaks straight back down. Any of these means the valve can no longer seal, and a fresh one restores a clean, leak-free charge.
Fitting and filling
The valve screws into the magazine baseplate. Use the correct valve key to avoid rounding it off, and a light coat of silicone helps it seal. To charge the mag, invert it and index your green gas can onto the fill valve on the base, as with any gas blowback magazine.
Back to full service
At under seven pounds this is a cheap way to rescue a dead 1911 magazine. Stock up on green gas at the same time, or book the mag in with our Kent repair and servicing team.
