Minelab CTX 3030 & GPZ 7000 Battery Seal O-Rings & Screw-On Cap

Keep your Minelab CTX 3030 or GPZ 7000 sealed and waterproof with this replacement O-ring kit. The battery compartment on both detectors relies on tight O-ring seals to maintain waterproof integrity, and worn seals compromise that protection. This kit includes three O-ring waterproof seals for the battery mount cap and one screw-on cap that protects the audio/headphone connector from dust and moisture when not in use.

Why detectorists choose this kit

• Maintain waterproof integrity: Three replacement O-rings restore factory-spec sealing on the battery compartment
• Protect the audio connector: Screw-on cap keeps dust and moisture out of the headphone jack between hunts
• Universal fit for two flagship models: Compatible with both the Minelab CTX 3030 and GPZ 7000
• Extend detector lifespan: Regular O-ring replacement prevents corrosion and water damage to internal electronics

When to replace O-rings

O-rings can degrade over time with regular use. If you notice the battery cap feels loose, if water intrusion has occurred, or if you hunt in saltwater or dusty conditions regularly, replacing the O-rings restores the seal. The GPZ 7000 and CTX 3030 both rely on these seals to maintain their waterproof ratings, and a compromised seal can allow moisture into sensitive electronics. Inspect O-rings regularly and replace if worn.

What's included

This kit contains three O-ring waterproof seals sized for the battery mount cap on the Minelab CTX 3030 and GPZ 7000, plus one screw-on cap for the audio/headphone connector. The O-rings are designed for the CTX 3030 and GPZ 7000 battery mount cap. Having spare O-rings on hand means you can swap a worn seal in the field without cutting a hunt short.
