The MistKing 3/8" Ball Valve (Val38BV12) is a straightforward manual shut-off valve designed for use with 3/8" tubing in MistKing misting systems. It gives keepers direct, on-the-spot control over water flow within their vivarium or terrarium misting setup — useful for isolating sections of a system during maintenance or adjusting coverage without dismantling pipework.
Compatibility
Sized for 3/8" line tubing, this ball valve integrates cleanly with MistKing distribution systems. It is a genuine MistKing spare, so fitment and performance within an existing setup is assured.
Practical Use
A ball valve at this size is a reliable way to manage flow across a misting network — whether you're running multiple vivariums from a single pump or simply want a manual override point on a specific branch. Turn it off to service nozzles or tubing without shutting down the entire system.
