Product Information
The Seac MX100 Set 230 Bar INT Diving Regulator Set is a complete scuba regulator system pairing a balanced diaphragm first stage with a lightweight second stage, an octopus, and a carrying bag, built around an INT (yoke) 230 BAR connection and made and assembled in Italy.
Who it is for
This set suits recreational divers who want a full regulator kit, from cold-water divers who benefit from the first stage's heat exchange system to anyone who prefers a yoke connection over DIN. Because it ships complete with a backup second stage and bag, it works well as a primary setup for new divers building out their first rig or as a reliable spare system.
Key details
The first stage is a balanced diaphragm design with a heat exchange system and a chromed brass body, fitted with a removable stainless steel valve seat for easier maintenance and replacement. It offers 2 high-pressure and 4 low-pressure outlet ports for flexible hose and accessory routing. The second stage is lightweight with low-friction mechanics for easy breathing and includes an adjustable Venturi effect lever so the diver can fine-tune airflow at depth.
Compatibility and sizing
This listing is the INT 230 BAR (yoke) connection version. Seac also offers the MX100 Set with a DIN 300 BAR connection as a separate variant for divers who need a DIN fitting.

Frequently Asked Questions
How often does a scuba regulator need servicing?
Follow the interval in your regulator's manual, since manufacturers commonly specify an annual inspection or a set number of dives and many warranties depend on it. A regulator is life-support equipment, so service belongs with a factory-trained technician rather than being attempted at home. Have it looked at sooner than scheduled if you notice increased breathing effort, free-flow, bubbles, or water in the second stage.
How do I rinse and care for a regulator after diving?
Make sure the dust cap is dry and firmly seated over the first-stage inlet before the regulator goes anywhere near water, because water inside the first stage is the leading cause of internal corrosion. Rinse in fresh water without pressing the purge button, since purging while depressurized can draw water back into the second stage. Shake out the water and hang it to dry with the hoses in wide, gentle loops rather than tight bends.
Can I fly with a scuba regulator?
Regulators travel well and are usually best carried in hand luggage where they will not be crushed or lost. A regulator holds no gas of its own, so there is nothing inherently problematic about it on an aircraft, though the airline and security screeners always have the final say. Pack it dry with the dust cap in place, in a padded regulator bag or wrapped in soft gear.
Can I use my regulator with nitrox?
Many modern regulators are supplied as suitable for nitrox mixes up to 40 percent oxygen, which is the widely used recreational industry standard, while anything above that requires dedicated oxygen-clean equipment and procedures. Confirm what your specific regulator's manual states, and follow your nitrox training and your fill station's requirements. Never assume a regulator is oxygen-service clean simply because it looks clean or is new.
What is the difference between DIN and yoke regulators?
A yoke (A-clamp) fitting clamps over the tank valve and is the most common connection across much of the recreational world, while a DIN fitting screws into the valve and is standard in much of Europe and in technical diving. DIN captures the o-ring inside the threads, which many divers consider more secure, but yoke is often what rental cylinders provide. Adapters exist in both directions, so check what is used where you dive before deciding.
What is the octopus regulator for?
The octopus is your backup second stage, carried so you can share air with a buddy who is out of gas, or breathe from it yourself if your primary fails or free-flows. It is normally on a longer, brightly colored hose so it is easy to find and hand over under stress. Secure it in the triangle between your chin and the bottom of your rib cage so it is instantly accessible and not dragging through sand or coral.
How should I store a regulator between dive trips?
Store it fully dry, out of sunlight, with the dust cap in place and the hoses in wide loops rather than tightly coiled. Avoid hanging it by the second stages for long periods, which stresses the hose fittings; laying it flat in a padded bag or hanging it by the first stage is kinder. If it has sat unused for a long stretch, have it checked before your next trip rather than assuming it is ready to dive.
Is the Seac MX100 regulator set available with a DIN connection?
Yes, Seac offers the MX100 Set with either an INT 230 BAR (yoke) connection or a DIN 300 BAR connection. This specific listing is the INT 230 BAR version, so if you need DIN, look for the DIN 300 BAR variant of the same MX100 Set.
What comes included with the Seac MX100 regulator set?
The Seac MX100 Set includes a first stage regulator, a second stage regulator, an octopus (alternate second stage), and a carrying bag. It is sold as a complete regulator set rather than a single regulator.
Where is the Seac MX100 regulator made?
The Seac MX100 regulator set is made and assembled in Italy. The first stage uses a chromed brass body with a removable stainless steel valve seat, reflecting Seac's standard manufacturing process for this diaphragm regulator line.
How many high-pressure and low-pressure ports does the Seac MX100 first stage have?
The Seac MX100 first stage has 2 high-pressure outlet ports and 4 low-pressure outlet ports. This gives divers enough ports to run a primary second stage, octopus, pressure gauge, and inflator hose at once.
