Single Outlet Scuba Tank Valves for Sidemount and Rebreather Configurations

Single outlet scuba tank valves are among the most common configurations used in recreational and technical diving thanks to their simplicity, reliability and versatility.

At MOMODIVE you will find a selection of single outlet scuba valves, DIN and Nitrox configurations, expandable valves, inline valves and compact valve systems compatible with steel and aluminum scuba cylinders.

Our catalog includes configurations with DIN G5/8, M26 Nitrox, M25x2 and M18x1.5 threads used in recreational, technical and specialized diving configurations.

Single Outlet Valves for Different Diving Configurations

Single outlet valves are widely used in many scuba diving configurations:

  • single tank recreational diving
  • technical diving
  • sidemount systems using expandable valves
  • CCR and rebreather systems using inline or non-expandable valves
  • pony bottles and compact auxiliary cylinders
  • drysuit inflation systems
  • oxygen, diluent and bailout cylinders

Thanks to the wide range of available configurations, divers can choose dedicated valves for recreational diving, DIR systems, sidemount, rebreather or auxiliary systems.

DIN G5/8, M26 Nitrox, M18x1.5 and Compatibility

Single outlet scuba valves are available with different connection standards and technical configurations.

Configuration Characteristics Recommended Use
DIN G5/8 Most common standard in recreational and technical diving Single tank, recreational and technical diving configurations
M26 Nitrox Dedicated Nitrox and oxygen-compatible configuration Nitrox cylinders, oxygen and O2 clean systems
M18x1.5 Thread commonly used on small cylinders and compact systems Drysuit inflation systems, pony bottles and auxiliary cylinders
M25x2 Most common thread standard on European scuba cylinders Steel and aluminum recreational and technical cylinders

Valves for Rebreather and CCR Systems

In CCR and rebreather systems, different valve configurations are used depending on the unit design, cylinder placement and intended use.

Many rebreather configurations use inline valves or non-expandable single outlet valves, appreciated for their compact profile, simplicity and efficient cylinder positioning.

These configurations can be used for:

  • oxygen cylinders
  • diluent cylinders
  • bailout cylinders
  • compact CCR configurations
  • O2 clean systems

Inline Valves, Expandable Valves and Sidemount Configurations

Inline valves are mainly used in CCR and rebreather systems where compact dimensions and clean cylinder layouts are important.

For sidemount diving, divers often prefer right and left expandable valves because they provide a wider profile better suited for lateral cylinder positioning and cave sidemount attachment systems.

The choice between inline, expandable or traditional single outlet valves depends on the specific configuration, cylinder placement and hose routing requirements.

O2 Clean Valves and Nitrox Configurations

Some valves are available in O2 clean configurations using Viton O-rings and oxygen-compatible components designed for high oxygen percentage mixes.

These systems are mainly used for:

  • advanced Nitrox diving
  • oxygen cylinders
  • CCR and rebreather systems
  • bailout cylinders
  • dedicated O2 clean configurations

Spare Parts and Components for Single Outlet Valves

Our catalog also includes a wide range of spare parts and accessories compatible with recreational and technical scuba valve systems.

  • service kits
  • O-rings
  • oversized handwheels
  • side plugs
  • manifold components
  • O2 clean spare parts

Our catalog includes valves and spare parts from major brands used in recreational and technical diving, including Scubatec, BtS, DIR Zone and Sunosub.

Frequently Asked Questions About Single Outlet Scuba Valves

What is the difference between DIN G5/8 and M26?

DIN G5/8 is the most common standard in recreational and technical diving, while M26 is used for dedicated Nitrox and oxygen-compatible configurations.

Are single outlet valves suitable for sidemount diving?

Yes, but sidemount systems often use right and left expandable valves because they are better suited for lateral cylinder positioning and cave sidemount attachment systems.

Which valves are commonly used on rebreathers?

CCR and rebreather systems commonly use inline valves or non-expandable single outlet valves depending on the unit configuration and cylinder placement.

What are M18x1.5 valves used for?

M18x1.5 threaded valves are mainly used on small cylinders, drysuit inflation systems, pony bottles and compact auxiliary cylinders.

Are O2 clean valves available?

Yes. Some configurations use Viton O-rings and oxygen-compatible components for Nitrox diving, CCR, rebreather and O2 clean systems.

Technical Diving, Rebreather and Sidemount Configurations

From recreational single tank setups to advanced rebreather, sidemount and DIR systems, choosing the correct valve configuration directly affects ergonomics, safety and gas management underwater.

Our catalog includes dedicated solutions for recreational diving, technical diving, DIR, sidemount and rebreather systems with carefully selected components designed for reliability, compatibility and simplified maintenance.

Explore the available configurations and choose the single outlet valve best suited for your scuba diving equipment.
