Quick Answer

The Sea Dragon Mini 1300 uses a specific O-ring set that includes two rings. A genuine replacement set is available from SeaLife to ensure a proper watertight seal.

Why Use a Genuine Replacement?

O-rings are critical for keeping water out of your dive light. Using a non-genuine or incorrect size O-ring can lead to leaks and potential damage. The SeaLife replacement set is designed to match the exact groove dimensions of the Mini 1300.

When to Replace Your O-Ring

Inspect the O-ring before every dive. Replace it if you see cracks, nicks, flattening, or if it no longer sits snugly in the groove. Regular replacement, at least once a year or after heavy use, is good practice.

Frequently Asked Questions

What size O-ring does the Sea Dragon Mini 1300 use?

The exact dimensions are not published by SeaLife, but the genuine replacement set (product ID 1776132) is guaranteed to fit the Mini 1300. Using a generic O-ring of unknown size risks a poor seal.

How many O-rings are in the set?

The replacement set contains two O-rings. One is for the battery compartment cap and the other for the charging port or head, depending on your light model. Keep both as spares, or replace both at the same time for even wear.

How do I install the new O-ring?

Remove the old O-ring and clean the groove with a lint-free cloth. Lightly lubricate the new O-ring with silicone grease (not included), then press it evenly into the groove. Avoid stretching or twisting the ring. Never use petroleum-based lubricants; they can damage the O-ring material.

Can I use an O-ring from another brand?

It is not recommended. O-ring cross-sections and groove depths vary between manufacturers. A mismatched O-ring may not seal properly, leading to flooding. Stick with the genuine SeaLife set for reliable performance.
