Tank accessories at Sopras Tek cover every component needed to configure, connect, and mount diving cylinders for technical use: isolation manifolds and modular valve parts across 232 bar and 300 bar pressure ratings, twin tank bands and complete double sets, stage and sidemount bottle rigging hardware, argon cylinder holders and sets, and single-tank mounting accessories. All valve and manifold components are available individually, allowing full configuration flexibility and individual part replacement.
Tank Accessories for Technical Diving
Valves
32 products across four subcategories: isolation manifolds (232 and 300 bar), modular left/right valve parts and SM valves (19 items), Nitrox/Argon valves (5 items), and rebreather valves (2 items). DIN G 5/8″ and M18×1.5 connection standards.
Twin tank gear
Stainless steel twin tank bands, double tank boots, EPDM tank protectors, and complete twin tanks sets (635–846 €) with cylinders, manifold, and bands in matched specification.
Bottle riggings
Stage bottle rigging sets for 130–160 mm, 7 L/S40, 10 L/12 L long steel, and S80. Sidemount bottle rigging, bungee straps in multiple lengths, neoprene hose holders for SM rigging, and stainless steel zip ties.
Others
Argon tank holders (0.5 L–1 L, 3 L), complete argon sets, pony mount system, rubber pad tank protectors, tank spacers, and tank straps with spacer for single-cylinder mounting.
Component Categories Explained
The accessories range is divided by function. Valves is the largest subcategory — it covers all valve and manifold hardware required to configure cylinder connections for backmount doubles, single cylinders, sidemount, and rebreather systems. The key decision in the valves range is matching pressure rating (232 bar or 300 bar), cylinder diameter (171 mm or 203 mm), and format (ISOL isolation manifold, screw SA, or screw LI) to your specific cylinders.
Twin tank gear provides the physical clamping hardware that holds two cylinders together as a backmount double set. The stainless steel tank bands must grip both cylinders without any movement — loose bands change the centre of gravity during the dive. Complete twin sets are available for divers building a double configuration from scratch.
Bottle riggings covers everything needed to sling a stage or decompression bottle. The core of any stage rig is a size-specific cam band set with bolt snap attachment at the neck and a bungee retainer at the base. The range includes cylinder-specific configurations to ensure correct fit on common aluminium and steel stage bottle sizes.
Others is the mounting and positioning hardware for cylinders that don’t fall into the manifold or rigging categories — argon bottle holders for dry suit inflation systems, pony bottle mounting for bailout configurations, and rubber protectors and spacers for single-tank backplate mounting.
What to Look For
- Pressure compatibility: All manifold and valve parts carry explicit 232 bar or 300 bar ratings in their product names. Mixing pressure-rated components from different ratings is a safety issue — verify compatibility before ordering.
- Cylinder diameter: Manifolds, twin tank bands, and rigging sets are sized for specific cylinder diameters (typically 171 mm or 203 mm for steel doubles; 130–160 mm for aluminium stage bottles). Measure your cylinders before ordering.
- Replacement parts vs. full assemblies: Modular valve parts (left/right parts, middle parts, closures) allow replacing individual components of an existing manifold rather than replacing the entire assembly. If one side of a manifold is damaged, identify the specific part number and replace only what is needed.
FAQ
Can I build a manifold from individual parts?
Yes — the Manifold parts and SM valves subcategory contains all modular components: left parts, right parts, middle parts (with and without isolation valve), and closures. This allows building a custom manifold or replacing specific components of an existing assembly. Ensure all selected parts share the same pressure rating and are compatible with your cylinder diameter and valve thread format.
What size tank bands do I need for my double set?
Stainless steel twin tank bands are sized to the cylinder diameter. The 760100/760121 bands at Sopras Tek cover the standard sizes for commonly used steel doubles. Confirm your cylinder outer diameter before ordering — using bands sized for a smaller diameter will not close correctly; bands for a larger diameter will not grip.
