Featuring left/right hose reversibility, adjustable breathing effort, and a highly efficient heat exchanger, it ensures smooth, reliable performance even in temperatures below 10°C. Its bright yellow design enhances visibility, while antimicrobial molded parts provide added hygiene. Lightweight braided hoses add flexibility and durability, making it a trusted backup regulator for serious divers. ## Description The XTX50 Octopus is our top-of-the-line Octopus in terms of features and performance. It provides the same features and performance as the XTX50 second stage and includes left / right hand reversibility. It comes with a high visibility yellow front cover and a 36" yellow hose. Suitable for cold water use (below 10 C / 50 F). Feature and Benefits The XTX50 Octopus has a breathing effort control knob. This allows the diver to desensitize the unit when it not being used. The XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used - press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge, i.e. when regulator clearing etc. Can be converted from a right-handed hose configuration to a left handed one. The process of changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must ONLY be performed by an APEKS Authorised Service Technician. Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable. Suitable for coldwater use. Compatible with EAN40 out of the box. Pneumatically-balanced second stage results in smooth, easy breathing. The large venturi lever has a soft touch rubber grip, which makes it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation. The large venturi lever has a soft touch rubber grip, which makes it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation. Manufactured with active protection against infection as all molded parts are produced with an additive that kills MRSA, protects against E-Coli, bacteria and fungi, and is also very effective against viruses, mould, yeast and algae. A silicone exhaust valve improves Review: Better than any primary I’ve used - This is an awesome regulator and requires almost no effort to breathe. Sits perfectly in the mouth and has the same air flow adjustability as the primary. If I didn’t also have the XTX50 primary, I’d be jealous. Review: Very low quality product. Not reliable. - Four dives!!! It’s all that this supposed premium gear lasted. On mi fifth dive the hose broke and started loosing air, forcing me to abort the dive. Fortunately the dive boat had a spare hose and I was able of changing it. Total crap. ## Features - Includes left/right reversibility - Cold water capability - Diver-adjustable controls for opening effort and venturi control - Excellent cold-water performance due to the highly efficient heat exchanger ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E5X01CK | | Best Sellers Rank | #244,647 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #3 in Diving Octopuses | | Brand Name | Apeks | | Customer Reviews | 4.5 4.5 out of 5 stars (17) | | Date First Available | October 20, 2013 | | Item Dimensions LxWxH | 1 x 1 x 1 inches | | Item Package Dimensions L x W x H | 9.1 x 7.4 x 5.7 inches | | Manufacturer | Apeks | | Package Weight | 1.45 Pounds | | Part Number | AA0342F | | Warranty Description | This product comes with a full manufacturer warranty. | ## Images ![by Aqua Lung XTX50 Octo Regulator - Image 1](https://m.media-amazon.com/images/I/61fS0VAyCvL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than any primary I’ve used *by B***R on February 19, 2023* This is an awesome regulator and requires almost no effort to breathe. Sits perfectly in the mouth and has the same air flow adjustability as the primary. If I didn’t also have the XTX50 primary, I’d be jealous. ### ⭐ Very low quality product. Not reliable. *by D***. on May 1, 2026* Four dives!!! It’s all that this supposed premium gear lasted. On mi fifth dive the hose broke and started loosing air, forcing me to abort the dive. Fortunately the dive boat had a spare hose and I was able of changing it. Total crap. ### ⭐⭐⭐⭐⭐ It's Apeks...It's Great *by A***E on September 26, 2018* With my tech set-up, I use this as my primary second stage. Absolutely the same as the standard all black XTX 50! I have had my original XTX 50 for a year now and it is just flawless. I added the Octo XTX 50 to complete the revamping of my older equipment and literally "Breathe Easier". ## Frequently Bought Together - Apeks by Aqua Lung XTX50 Octo Regulator - BUSY-CORNER 166 Pieces Scuba O-Ring Kit Scuba Diving Rubber Orings, for Dive Hoses Ring Diving Dive Gear Equipment Scuba Tanks NBR90 - Athletico Scuba Regulator Bag --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1344242-by-aqua-lung-xtx50-octo-regulator](https://www.desertcart.tn/products/1344242-by-aqua-lung-xtx50-octo-regulator) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-29*
