Product Information
The Aqualung Pressure Gauge Assy PSI Black/Black (SKU NS114123) is a single submersible pressure gauge (SPG) on a 36 in (91.44 cm) hose that reads cylinder pressure to 5,000 PSI / 350 bar through a Swiss-made, shock-resistant Bourdon tube, and it adds an integrated temperature scale and a one-way safety valve in the same easy-to-read display.
Who it is for
This gauge suits divers who want a standalone pressure reading instead of a multi-gauge console. Running an SPG alone keeps the setup light and reduces what has to be managed underwater, which works well for divers who already use a dive computer for depth and time and only need gas pressure on an analog gauge. Nitrox compatibility up to 50% means it can stay on the regulator for enriched air dives within that range, and the luminescent face helps on night dives, wreck penetrations and other low-light conditions.
Key details
- Pressure range: up to 5,000 PSI / 350 bar, scaled in psi on this version.
- Mechanism: Swiss-made, shock-resistant Bourdon tube movement.
- Hose: 36 in (91.44 cm) high-pressure hose that connects to a first-stage HP port.
- Display: luminescent gauge face with an integrated temperature scale.
- Safety: one-way safety valve that limits gas loss if the lens is damaged.
- Gas: nitrox compatible up to 50%.
Compatibility and sizing
The assembly is sold complete with its hose and attaches to the high-pressure port of a first stage, so no console boot or separate hose is needed. Aqualung publishes this gauge in two scale options, BAR and PSI; this listing is the PSI (imperial) version in black/black.
DiveCatalog.com is an authorized Aqualung dealer and a real dive shop in Irvine, California since 2003. Call or chat with us at 888-701-4017 if you want help confirming the gauge scale or how it fits your current first stage.

Frequently Asked Questions
Can I use this Aqualung pressure gauge with nitrox?
Yes. Aqualung lists this pressure gauge as nitrox compatible up to 50% oxygen, so it can stay on your regulator for enriched air dives within that range. For mixes above 50%, use equipment rated for that service. The gauge reads to 5,000 PSI / 350 bar through a Swiss-made, shock-resistant Bourdon tube.
How long is the hose and does it come with the gauge?
The hose is 36 inches (91.44 cm) and is part of the assembly, so the gauge arrives ready to thread into the high-pressure port of a first stage. No separate hose purchase is needed.
Does this gauge show water temperature too?
Yes. The Aqualung Pressure Gauge has an integrated temperature scale on the same dial as the pressure scale, so remaining air pressure and water temperature are read in one glance. The face is luminescent, which keeps both scales readable in low light such as night dives, deeper water or inside a wreck.
What does the one-way safety valve do?
The one-way safety valve limits gas loss if the gauge lens is damaged. Instead of venting the cylinder contents through a broken face, the valve restricts flow, which helps protect your remaining gas supply. It works alongside the shock-resistant Swiss-made Bourdon tube mechanism, which is built to tolerate the knocks a gauge takes in normal diving use.
