Orbit Series
Moon
3000 PSI Gas Bottle
A compact Type III composite pressure vessel offered in 8-liter and 10-liter configurations for applications that need high-pressure gas storage in a lightweight, space-efficient package.

Compact high-pressure gas storage
Two proven sizes in one compact platform.
Moon is available in 8-liter and 10-liter configurations, allowing system designers to select capacity without moving to a substantially larger vessel envelope.
Steelhead's supplied product literature identifies both configurations as 3000 PSI gas bottles certified to UN/ISO 11119-2 and DOT requirements. The standard configuration includes a CGA350 1.125-inch UNF straight Sherwood 212F valve with the small end plugged.

UN/ISO + DOT
Certified to UN/ISO 11119-2 and DOT requirements.
Technical data
Moon configurations
Dimensions and masses below are taken from Steelhead's supplied 3000 PSI Gas Bottle product literature.
| Nominal Volume | Boss-to-Boss Length | Length with Adapter | Mass with Adapters | Outside Diameter |
|---|---|---|---|---|
| 8 L (2.1 gal) | 622 mm (24.5 in) | 652 mm (25.6 in) | 8.5 kg (18.7 lb) | 173 mm (6.8 in) |

Specifications are based on the supplied Steelhead product information and should be reconfirmed against the current production drawing if the configuration has changed.
Standard configuration
Configured for straightforward system integration.
Valve
CGA350 1.125-inch UNF straight Sherwood 212F valve.
Opposite End
Small end plugged in the standard configuration described by Steelhead.
Vertical Storage
A boot for vertical storage is identified as an available upgrade.
Why Moon
Compact packaging for constrained installations.
Moon gives engineers an 8-liter or 10-liter high-pressure storage option within a 173 mm (6.8 in) outside diameter. That compact footprint makes the platform useful where available installation space is a primary system constraint.
The two standard lengths also make it possible to increase stored volume while maintaining the same vessel diameter and a common product-family architecture.
Applications
Built for compact commercial gas-storage systems.
Moon is best positioned where compact packaging, portability and certified high-pressure storage are important design considerations.
Marine & Specialty Gas
Compact gas storage for space-constrained marine and specialty installations.
Mobile Systems
Suitable for equipment and platforms where vessel footprint and weight matter.
OEM Integration
Two standard volumes give designers a practical starting point for packaged systems.
