XP MI-6 and MI-4 Pinpointer Flat Rubber Washer Replacement Part

This flat rubber washer fits the XP MI-6 and MI-4 pinpointer models. Both pinpointers share the same end-cap seal design, where the washer compresses between the battery compartment housing and the threaded cap to form a waterproof barrier. If you notice moisture inside the battery compartment after wet hunts, this replacement washer restores factory waterproof performance.

The washer needs replacement when it shows permanent compression, cracking, or loses its springy feel. Inspect the washer periodically, especially following any hunt where the pinpointer took a hard drop onto rocks or concrete. If you see moisture, condensation, or corrosion inside the battery compartment, replace the washer immediately before the next wet hunt. Detectorists working saltwater beaches or muddy fields replace washers regularly as preventive maintenance. The rubber material degrades from UV exposure, temperature cycles, and saltwater contact over time, making periodic inspection important for maintaining waterproof integrity.

You can reuse the old washer if it shows no cracking or permanent deformation and still maintains its original thickness and flexibility. If the washer shows thread grooves or feels brittle, replace it even if it looks visually intact. Rubber degrades from UV exposure, temperature cycles, and saltwater contact long before visible cracking appears. Replacing a marginal washer prevents costly repairs from water damage, and keeping a spare in your dig pouch prevents mid-hunt seal failures. The washer's rubber material is designed to provide reliable sealing when in good condition.

To install the replacement washer on your MI-6 or MI-4 pinpointer, ensure the washer sits flat in the battery compartment seal area with no twists or folds. The rubber washer creates a waterproof barrier when properly positioned between the housing and end cap. Avoid overtightening the end cap, as this can crush the washer and shorten its lifespan. Hand-tight installation is typically sufficient for a proper seal. After installation, verify the seal is functioning correctly before using the pinpointer in wet conditions to ensure moisture protection.

This washer is designed specifically for the XP MI-6 and MI-4 pinpointers and will not fit other brands or models. Pinpointer seal designs vary widely across manufacturers in terms of diameter, thickness, and compression geometry. Using an incorrect washer compromises waterproof integrity and can allow moisture into the electronics. If you own a Garrett, Nokta, or Minelab pinpointer, source the correct replacement seal from that manufacturer. For guidance on selecting the right pinpointer and maintaining its seals, see our best pinpointers for metal detecting comparison guide.

Keeping spare washers on hand ensures you can replace a worn or damaged seal when needed without interrupting your detecting activities. The washer's small size and low cost make it practical to stock extras in your dig pouch or vehicle kit. Having a spare available allows immediate replacement if you notice moisture during a hunt, preventing potential water damage to your pinpointer's internal components. The rubber material is a consumable item that will eventually need replacement with regular use, making spares a practical investment for maintaining your MI-6 or MI-4 pinpointer's waterproof performance.

The washer is a replacement part for the XP MI-6 and MI-4 pinpointers. Rubber seals are wear items expected to degrade with normal use, similar to batteries or coil covers. If the washer arrives damaged, cracked, or fails to seal properly when installed correctly, contact the retailer for assistance. The product includes one rubber washer designed to restore waterproof performance to your pinpointer's battery compartment. Proper installation and periodic inspection help ensure the washer maintains its sealing function throughout its service life.

The rubber washer is designed to create a waterproof seal in the MI-6 and MI-4 pinpointer battery compartment as supplied. The washer material provides sealing properties when properly installed between the housing and end cap. Maintaining the washer in good condition and replacing it when it shows signs of wear, cracking, or permanent compression ensures continued waterproof performance. Clean any residue from the housing threads before installing a fresh washer to ensure proper contact and sealing. Regular inspection of the washer helps identify when replacement is needed to maintain waterproof integrity.

Hunting with a worn washer can allow moisture to enter the battery compartment, potentially causing damage to internal components. Water intrusion is particularly problematic in saltwater environments, where corrosive effects are accelerated. If you notice any performance issues after wet hunts, inspect the battery compartment for moisture and replace the washer immediately. The rubber washer serves as the primary waterproof barrier for the MI-6 and MI-4 pinpointer battery compartment, making its condition critical for protecting internal electronics. Regular washer inspection and timely replacement help prevent moisture-related damage and maintain reliable pinpointer operation.

This is a replacement washer for the XP MI-6 and MI-4 pinpointers, designed to restore the waterproof seal in the battery compartment.
