Product Information
The Oceanic Delta 5 Second Stage Dive Regulator is a second-stage-only demand valve built around a pneumatically balanced all-metal valve, a dive/pre-dive switch with patented Dynamic Airflow Adjustment control and a compact 2.5 inch circular front profile. It is offered in black (SKU 40.7595.07) and white (SKU 40.7595.24) and is rated for nitrox from standard air up to 40% oxygen.
Who it is for
It suits divers who need a second stage to pair with a first stage they already own, for cold-water or warm-water diving. The dive/pre-dive switch and airflow adjustment let you tune breathing effort at the surface and at depth, and the mechanical purge button keeps airflow stable while purging. Because this listing is the second stage on its own, it can serve as a spare or replacement second stage for your Delta 5 setup.

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.
Does the Oceanic Delta 5 second stage come with a hose?
No. This listing is the second stage only, and the Miflex braided hose is supplied with complete Delta 5 models. Plan on connecting it to the low-pressure hose already on your first stage, or sourcing a hose separately. If you are unsure which hose length or fitting you need for your setup, contact us before ordering and we will help you confirm it.
What colors and part numbers are available?
The Delta 5 second stage is offered in two colors: black, part number 40.7595.07, and white, part number 40.7595.24.
What does the dive/pre-dive switch actually do?
The dive/pre-dive switch, combined with Oceanic's patented Dynamic Airflow Adjustment control, lets you change how freely the second stage delivers air. The dive/pre-dive switch works with Oceanic's patented Dynamic Airflow Adjustment control to change how freely the second stage delivers air. The mechanical purge button keeps airflow consistent whenever you clear the regulator.
What first stage is the Delta 5 second stage designed to work with?
In Oceanic's complete Delta 5 system the second stage is paired with the eDX first stage, a balanced diaphragm design that is environmentally sealed and cold-water ready. The Delta 5 includes a heat exchanger for enhanced cold-water performance. Call 888-701-4017 or chat with us if you want to confirm the pairing with a first stage you already own.
Review summary
Reviewers across both sources agree this second stage breathes easily, with two of them calling inhalation effortless and performance solid. Ratings sit at 4.5 out of 5 on both sources that report them, and divers reporting back after early outings say it is holding up well. Good to know: one diver found no hose in the box and an older hose that did not thread on, so confirm the hose and fitting you need. A sensible pick for recreational divers who want straightforward, easy breathing and already have or can add a matching hose.
