MistKing 3/8" Bulkhead Fitting with O-Ring & Plug for Misting Systems

A 3/8-inch bulkhead fitting designed for use with MK misting systems, supplied complete with an O-ring and blanking plug. Used to create a watertight port through a reservoir, enclosure wall, or sump panel — essential when routing misting lines into or out of a sealed container without leaks or pressure loss.

What's Included

• 3/8" bulkhead fitting compatible with MK misting system components
• O-ring for a secure, watertight seal against the mounting surface
• Blanking plug to cap the port when not in use

Where It's Used

Bulkhead fittings are the correct way to pass a water line through a tank wall, cabinet panel, or reservoir lid. The O-ring compresses against the surface to prevent seepage, and the included plug lets you seal off unused ports cleanly rather than leaving them open or improvised.

Compatibility

This fitting is a genuine MK misting system spare, sized at 3/8 inch to match standard MK line and reservoir fittings. If you're expanding an existing MK setup, adding a secondary reservoir, or replacing a damaged bulkhead, this is the correct part to use rather than an off-the-shelf plumbing alternative.

Keeping spares like this to hand means a leaking or damaged port can be replaced quickly — avoiding downtime for humidity-dependent species that rely on consistent misting schedules.
