These incredibly tiny 3-way solenoids aren't used in any guns that we know of, but their small size may be perfect for crazy tinkering projects. They have a 5vdc coil and are rated at 0.5MPa (around 72psi). We recommend using 5/64"/2mm ID hose with them.
These solenoids come with no warranty - they are brand new and unused, but due to the pressures and cycle rates that many guns subject the valves to, most solenoid manufacturers refuse to honor warranties when their products are used in paintball applications. As such, we are unable to offer warranties when the manufacturers won't.
