Product Information

The Ocean Reef SL35TX Nitrox M26x2 (code OR009927) is a balanced diaphragm scuba first stage built specifically for enriched air diving. It uses M26x2 screw threading in accordance with EU rules. It is rated for Nitrox mixes up to 100% straight out of the box. It is CE certified and includes an anti-freeze kit.

Who it is for

This first stage suits Nitrox divers who want a first stage rated for enriched air mixes up to 100% out of the box. It is also used as the first stage component on Ocean Reef Neptune III and Neptune Space full face mask systems, making it a fit for divers running those full face setups on Nitrox fills.

Compatibility and sizing

The M26x2 screw threading on this first stage is a distinct connection from Ocean Reef's standard SL35TX INT (yoke) and SL35TX DIN first stages, which are air-only and are not rated for Nitrox use. Pair this first stage with Nitrox cylinders or cylinder valves that meet EN 144-3 for enriched-air filling.

Frequently Asked Questions

Is the SL35TX Nitrox M26x2 the same as the SL35TX DIN or SL35TX INT first stage?

No. The SL35TX Nitrox M26x2 (code OR009927) uses M26x2 screw threading and is rated for Nitrox mixes up to 100% out of the box, while the SL35TX INT (yoke, code 9922) and SL35TX DIN (code 9923) are air-only first stages that Ocean Reef's manuals state must not be used with Nitrox.

What tank valves does the SL35TX Nitrox M26x2 work with?

It connects via its M26x2 screw threading to Nitrox cylinders and cylinder valves meeting EN 144-3 for enriched-air use.

Does this first stage need special servicing before diving Nitrox?

It ships with Viton O-rings and Christo lube grease and is compatible with Nitrox mixes up to 100% out of the box.

Can the SL35TX Nitrox M26x2 be used with Ocean Reef full face masks?

Yes. It serves as the first stage component on Ocean Reef Neptune III and Neptune Space full face mask systems, giving those setups a first stage already rated for Nitrox use.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.
