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

A genuine MistKing replacement O-ring and plug for 1/4" metal bulkhead fittings. An essential spare for any keeper running a MistKing misting system who needs to maintain a watertight seal or cap off an unused bulkhead port.

What It Does

The O-ring ensures a secure, leak-free seal where the metal bulkhead passes through a reservoir or enclosure wall. The plug allows you to block off a bulkhead fitting that is not currently in use, keeping your system clean and pressure-stable.

Compatibility

Designed specifically for MistKing 1/4" metal bulkhead fittings. If you are running MistKing components, this is the correct replacement part — do not substitute with generic alternatives that may not seat correctly and could cause leaks.

When to Replace

• O-ring has hardened, cracked, or is no longer seating flush
• Bulkhead joint is weeping or dripping during system operation
• Carrying out routine maintenance on your misting setup
• Capping an unused port on a multi-output reservoir

Keeping a spare O-ring and plug on hand means a small fitting issue never has to interrupt your animals' humidity schedule. A straightforward part that keeps your misting system running exactly as it should.
