Self-Inflating Pump Green Cap (Spare Part)

A replacement green cap for the Travel X self-inflating pump.

Fits: Self-Inflating Plane Bunk and Self-Inflating Plane Foot Cushion.

The green cap sits over the pump once it's twisted into its grey housing, and turns clockwise until tight. It's the part that seals the housing and stops air escaping, so it's needed even when the pump is taken out of the housing.
