Brand: Apeks

Model: XTX40 Octopus

SKU: 40452

The Apeks XTX40 Octo is a reliable alternate with the same design as the rest of the XTX range with a Venturi lever and reversible design. Designed to meet the demanding coldwater standards the XTX 40 has a balanced valve for performance, an inlet heat exchanger, full metal valve barrel and venturi to ensure performance and reliability even in extreme cold conditions.

The inlet heat exchanger and full metal valve barrel help to disipate the cold generated as air decompresses between each stage, reducing the potential risk of ice crystals forming on critical components.

A venturi lever allows control of the air flow within the housing, directing it to either provide full performance and air flow or free flowing protection by forcing air back towards the diaphragm.

The XTX40 is finished off with a high visibility yellow front cover and trim and is fitted with a standard length braided octopus hose. The braided hose offers improved UV protection over traditional rubber hoses and also significantly raises the burst pressure of the low pressure hose.

Apeks XTX40 Octopus - Features

FeatureProduct Specification
Adjustable Inhalation
This feature allows the diver to adjust the inhalation setting from the set level and increase the effort required to open the 2nd stage valve to deliver air. Close.
Adjustable Venturi
The venturi control affects how air flows in the 2nd stage. In it's positive position the flow of gas creates a vacuum against the diapragm, helping to open the valve. In it's negative position it will divert gas back against the diaphragm helping to close the valve. It is basically used to help prevent free flowing. Close.
Cold Water Rated
Cold water has adverse effects on regulators and can cause some to freeze so each regulator combination must be tested during manufacturing for their performance in different water temperatures.

Cold water is defined by EN250 as below 10°C. If a regulator combination cannot meet the performance standards below 10°C then they are only suitable for warm waters.

EN250 / (EN250A >10°C)
To pass the regulator must provide at least 62.5 L/min of air at 50M depth above 10°C. Close.
Cold & Warm Water
Environmentally sealed
Environmentally sealed 1st stages offer greater protection against freezing when diving in cold water (below 10 degrees C)

Scubapro have a new method of cold water proofing their first stages called the eXtended Thermal Insulating System or XTIS which still allows water into the first stage but the internal parts that come into contact with the water are coated to prevent ice from forming. Close.
First Stage
Unbalanced regulators are affected by the pressure in the cylinder, becoming slighty harder to breathe from when the pressure starts to drop.

Balanced regulators are not affected by the cylinder pressure or depth.

Over-balanced regulators achieve unprecedented performance by increasing your air supply the deeper you go providing the best breathe for deep divers. Close.
High Pressure Ports
High pressure ports supply the pressure gauge and wireless transmitters for dive computers Close.
Low Pressure Ports
Low pressure ports supply the 2nd stages and inflator hoses Close.
Service Information
All regulators need to be serviced to keep them in working order as the parts inside them age and wear over time and with use. Most regulators need to be serviced once a year or after 100 dives with normal recreational use to replace parts and re-balance.

Some regulators use more modern materials or mechanisms that allow them to extend the servicing interval that can save you some money in the long run. Close.
1 Year - 100 Dives
Weight in Grams (approx)
The weight includes the first stage (DIN fitting), hose and second stage. Close.

Excellect price

I needed an additional set up, which was capable of diving in cold water, so I went for the Apeks XTX40. I bought the Octo second stage from Simply Scuba, and it came with a low pressure hose. I already had the first stage regulator, so I didn't want to buy a full set.

Unfortunately Simply Scuba don't sell the black second stage separately, so I bought one from a well known outlet. This was more than £10 more expensive, and did not come with an hose.

I'll stick with Simply Scuba next time!

I'd be happy with the XTX40 as my main reg. It's comfortable in the mouth and breathes well even with the venturi set on full '-', as it will be when stowed. It's therefore perfect as an octopus. The hose is robust yet flexible so also good for ret
