Rating: Great made even better
Reviewer: Jason Kuhn
I bought this for my wife after owning my Delta 4.1/FDX-10 for a few years...now I want the Delta 4.2 with MaxFlex hose! It was already a great regulator, with the braided MaxFlex hose it is even better. No complaints!

Excellent product, this is my first Regulator and found it incredible! Maxflex cord is really comfortable and you can dive without worries about damaging sea life and reefs. Simply the best! Also the dry valve allows you to choose the type of air (wet or dry) you wish to breath while diving... I am very happy with this product!

Questions and Answers for Oceanic Delta 4.2 /FDX-10 Regulator Maxflex with Dry Valve Technology:


  • Matty:

    Hi There Just wondering if this regulator is corrosion resistant?? Thanks! :)

    Bob  (Certified Scuba Instructor at Scuba.com):

    All scuba regulators are considered corrosion resistant. Bearing in mind that they need to be rinsed off after use and you never want water to enter the 1st stage.

  • Adam:

    Does it have a purge button? It looks lk it does but it isnt mentioned.

    Greg  (Certified Scuba Instructor at Scuba.com):

    Yes, all second stage regulators have a purge button.

  • Michael(Mike):

    Is the DVT fail-safe

    Bob  (Certified Scuba Instructor at Scuba.com):

    The DVT is a one-way check valve located between the tank valve and the 1st stage mechanisms. So long as the valve is on and there is pressure in the cylinder, the system is fail safe.

  • Marc:

    Some people say it support cold water but the oceanic web site description dont mention it: http://www.oceanicworldwide.com/us/delta-4-2/ Oceanic mention cold support only for omega 3 and zeo but uk web site say it support cold: http://www.oceanicuk.com/equipment/regulators/delta-4-2-fdx10/ who is the liar?

    Arthur  (Certified Scuba Instructor at Scuba.com):

    Good morning, all regulators are designed to handle cold water, preventing freeze up. Now it you doing some ice diving you might want a specialty first and second stage.

  • randy:

    what is the difference between the 4.2 and the 4.1? is there a functional difference?

    Aaron  (Certified Scuba Instructor at Scuba.com):

    Hi Randy, The difference is in the connection to the 2nd stage. Delta 4.2 has the comfort swivel on it.

DELTA 4.2
Even with the best laid dive plans, there are times you encounter conditions beyond your control. The Delta 4.2 is one hot new regulator ready to take on all challengers with a new stylish look and FDX-10 First Stage featuring DVT ( Dry Valve Technology).

Cosmetic makeover with new stylish colors
Diver adjustable inhalation effort
Patented Orthodontic Mouthpiece with high-density bite tabs
Patented Dynamic Adjustment automatically maintains inhalation effort throughout the dive
Adjustable Venturi Switch (A.V.S.) for simple Dive/Pre-Dive Adjustment
Inline ball swivel for reduced jaw fatigue and comfort
Paired with the FDX-10 Over-Balanced Diaphragm First Stage available with Oceanic's DVT (Dry Valve Technology)
Now available with MaxFlex Hose which is a lightweight, flexible, Braided hose designed to outperform and outlive traditional rubber hoses.

Dry Valve Technology (DVT)

DVT is a revolutionary regulator technology designed to automatically eliminate moisture and contaminants from entering your first stage, even if the dust cap is accidentally left off.

DVT eliminates corrosion of critical internal components, bacteria, hose deterioration, and damaged gauges and computers.

Diver Adjustable Inhalation Effort

A simple twist of the adjustment knob enables complete control...

Set the inhalation requirement to near zero when you need ultimate performance, or tune it for greater resistance as conditions or preferences change.

Patented Dynamic Adjustment

A common objection to adjustable second stages is that divers can't imagine themselves twisting and turning a knob as they descend and ascend through the depths. If inhalation resistance is set near zero at depth, your ascent would require you to manually increase resistance as ambient water pressure is reduced to prevent free-flow. Taking another stride beyond common second stage engineering, Oceanic designed a patented DYNAMIC ADJUSTMENT feature into the heart of the Delta 4.2. This mechanically balanced valve maintains a preferred breathing resistance throughout the dive. Set it once and the Delta 4.2 automatically adjusts to make breathing as easy at 100 feet as it is at 30 feet - with no additional manual adjustment.

Diver adjustable inhalation effort
Most downstream demand valve regulators are calibrated during manufacturing to a single, 'middle of the road' operation. Whether finning up current at 100+ feet or merely snorkeling out to the dive site, this factory adjustment may not be optimum for the wide variety of demands we place on our equipment. A simple twist of the Delta 4.2's adjustment knob enables complete control...set the inhalation requirement to near zero when you need ultimate performance, or tune it for greater resistance
as conditions or preferences change.

Adjustable Venturi System (A.V.S.)
The A.V.S. deflector vane found in the Delta 4.2 diverts the airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation. With the addition of a user Adjustable Venturi System (A.V.S.), in the form of a simple yet ingenious switch, full adjustment control rests in the hands of the diver.

Inline Swivel
Ever notice that nearly every picture you see of a diver, their regulator looks like it’s not the least bit comfortable? The Delta 4.2 features an ergonomically designed in-line swivel for ultimate comfort.

Improved Adjustment Mechanisms
Both the Dynamic Adjustment Knob and A.V.S. Switch are designed to be unobtrusive, yet easily manipulated even with the thickest gloves.

Surge Deflector
Our surge protector (the titanium, blue or yellow that you see in the images above) reduces freeflow caused by surge or oncoming current.

Computer optimized design
Oceanic regulators are exclusively designed using the latest 3-D computer modeling techniques. This allows us the ability to model and test performance while still in the early stages of development. The Delta 4.2's unique deflector vane and housing design diverts airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation.

Lightweight
The Delta 4.2's housing is made from an ABS/Polycarbonate composite blend of materials making the Delta 4.2 both extremely rugged and lightweight (6.7 ounces) and nearly neutrally buoyant underwater, reducing jaw fatigue on extended dives. The extremely ligweight cover ring is machined from a solid piece of aircraft aluminum, and then hard anodized, utilizing a unique process to prevent corrosion.

Patented Orthodontic Mouthpiece with High-Density Bite Tabs
To further reduce jaw fatigue, the Delta 4.2 features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw.

Nitrox Compatibility
The Delta 4.2 is classified as being suitable for use with nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts.

FDX-10 Balanced Diaphragm First Stage
Forged from marine-grade brass, the FDX-10 features optimized air paths and angled hose ports for superior performance and comfort. A sealed Balanced Diaphragm design, Enviro Kit and patented DRT TM (Dry Regulator Technology) isolate all internal components from the environment. 2 high pressure and 4 low pressure ports allow convenient and comfortable hose routing.
