- Notes
- Dust cap for the hydraulic breakaway coupling on the Farmall H, M and Super M and the 300, 350, 400 and 450. As a dust cap it covers the coupling when no hose is attached. Precision Tractor Parts sells a reproduction for $25. A small cover with no structural load, so it suits printing in PETG once the coupling's diameter and retention are measured and it is confirmed that the cap does not hold pressure.
