MistKing 1/4" Metal Bulkhead O-Ring & Plug – Misting Spare

A replacement O-ring and plug set for MK 1/4" metal bulkheads, designed to keep your reptile misting system sealed and leak-free. Essential to have on hand if you're maintaining or repairing a vivarium or terrarium misting setup.

What's Included

This pack contains the O-ring and plug specific to the MK 1/4" metal bulkhead fitting. Both components work together to seal unused or temporarily inactive bulkhead ports, preventing water loss and maintaining pressure across your misting system.

When You Need This

• Replacing a worn or damaged O-ring on an existing MK 1/4" metal bulkhead
• Blanking off an unused bulkhead port in a vivarium or terrarium wall
• Routine maintenance to prevent drips or slow leaks around bulkhead fittings
• Keeping a spare set ready to minimise system downtime

Compatibility

Sized specifically for MK 1/4" metal bulkhead fittings. If you're running a misting system with these fittings throughout your reptile setup, this is the correct replacement hardware — not a universal part.

Keeping a spare set of seals and plugs means a minor leak or worn fitting doesn't have to interrupt your misting schedule or put humidity-dependent species at risk.
