The valve is sealed by high pressure, it won't leak when the pressure up to 3~4MPa.We have tested well and set best pressure before shipping, so you'd better not adjust or disassemble valve and regulated pressure part at will..To install them, you only need to keep the original barrel, grip & trigger set, and Push Probe.It can be shot about more than 20~50 times.(Due to pressure set, spring size and length of cylinder)..Band is necessary for long barrel(more than 10"), you can find it from our store.Don't care about the spare accessory package until maintenance is needed.Contact us for installation instructions when you get it.
