Description

Machined from solid Delrin, this cap protects the fine, sensitive threads on the MK/Gemini head where the breathing loop attaches. These threads are easy to damage and tend to collect grit when the unit is packed with other gear. The cap keeps them covered during travel, storage, or long surface intervals - and also keeps bugs and other critters out of the head.

The cap is vented to prevent potential negative pressure when used with a head cover.

Fits MK/Gemini units released before November 2025. Newer production uses the bayonet connection, which is not compatible. No retrofit options exist for that version.

Sold as a single item or a set of two.

This is not an official Fathom accessory.
Designed in California, made in China.

IMPORTANT - LIFE-SUPPORT EQUIPMENT

Scuba diving and technical diving (including mixed-gas, decompression, cave, wreck, and rebreather diving) are inherently hazardous activities that can result in serious injury or death. Products sold by Rugged Scuba are components of, or accessories to, life-support equipment. By purchasing any such product, you expressly acknowledge and assume all risks associated with its use.

Training required

Use only if you are currently certified for the type of diving and equipment configuration in which the product will be used. Do not use beyond the limits of your training, experience, or physical fitness.

Inspection and service

Inspect every product before every dive. Do not use if damaged, corroded, leaking, out of test, or otherwise suspect. Service and replacement must be performed in accordance with the manufacturer's instructions and by personnel qualified for the specific equipment. Rugged Scuba does not service regulators, rebreathers, or other life-support components, and does not certify third-party service.

Compatibility

You are responsible for verifying that every product is compatible with your specific regulator, cylinder, valve, rebreather, and gas mix before use. If unsure, consult a qualified scuba technician.

Aftermarket accessories

Certain Rugged Scuba products are aftermarket accessories for equipment manufactured by third parties (including but not limited to JJ-CCR, Fathom Dive Systems, iQsub, Halcyon, and Light Monkey). Those products are not manufactured, endorsed, or authorized by those OEMs; all trademarks are property of their respective owners and are used only for compatibility identification. Use of any aftermarket accessory may affect your OEM warranty.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATION MAY NOT APPLY TO YOU.

Indemnification

You agree to indemnify, defend, and hold harmless Rugged Scuba, its owners, officers, employees, and suppliers from and against any and all claims, losses, damages, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising from or relating to your use, misuse, or modification of any product, your breach of these terms, or your breach of any applicable law or regulation.
