Lionel O Gauge Knuckle Coupler Pins & Springs – 12 Sets, Black/Silver, Parts

Keep your Lionel O gauge trains running smooth with these replacement knuckle coupler pins and springs.

This set includes 12 complete sets—enough to handle multiple cars or keep spares on hand.

The pins come in a mix of black and silver, so you’ve got options depending on the look you’re going for.

They’re brand new and unbranded as far as MPN/UPC, but they’re made for Lionel couplers and fit the standard O gauge.

If you’ve got a coupler that’s not snapping back or a pin that’s gone missing, these will get you back on track.
