Seamless steel CNG cylinder
Manufactured from seamless chrome-molybdenum steel billets, hot-spun at both ends, quenched and tempered, then proof-tested at 300 bar. This is the cylinder most Indian retrofitters fit, and the one we make the most of.
- Working pressure 200 bar, test pressure 300 bar.
- Design life 18 years with statutory re-testing every 3 years.
- Epoxy-polyester powder coating for corrosion resistance in coastal service.
- Neck threading to your valve specification (25E or M18×1.5).
- Water capacity35 – 90 L
- Material34CrMo4 / SAE 4130
- StandardISO 11439, IS 15490
- ApprovalPESO design registered
Composite overwrapped cylinder
A seamless aluminium liner fully overwrapped with carbon fibre in an epoxy matrix. Roughly half the weight of an equivalent steel cylinder, which matters when payload or rear-axle load is the constraint.
- Up to 55% lighter than a steel cylinder of the same capacity.
- Non-corroding — no rust risk at the strap contact points.
- Damage-tolerant winding validated by cycle and drop testing.
- Optional protective sleeve for exposed under-body mounting.
- Water capacity45 – 80 L
- Liner6061-T6 aluminium
- OverwrapCarbon fibre / epoxy
- StandardISO 11439 Type 3
Auto rickshaw cylinder & cradle set
Short-format cylinders sized to the chassis rails of the common three-wheeler platforms, supplied as a set with a formed cradle, twin straps, anti-abrasion pads and fasteners so the workshop is not fabricating brackets.
- Chassis-specific cradles — no drilling or on-site fabrication needed.
- Vibration-validated to 200 km/day urban duty cycles.
- Anti-abrasion pads at every strap contact point.
- Under-seat or rear mounting variants available.
- Water capacity20 – 35 L
- MountingCradle + twin strap
- SegmentAuto rickshaw, e-rick hybrid
- Supplied asComplete fitment set
Valves, regulators & retrofit kits
Everything between the cylinder and the engine. We supply cylinder valves with integrated excess-flow and thermal pressure relief, high-pressure tubing, the filling receptacle, the reducer and the changeover switch — matched and pressure-tested as a set.
- Manual or solenoid cylinder valves with PRD.
- Excess-flow protection in the valve body.
- Sequential and venturi kit compatibility.
- Installer training available at your workshop or ours.
- Valve typeManual / solenoid
- Safety devicesPRD + excess flow
- TubingSeamless SS, 6 mm
- Kit typeSequential & venturi
