Made to Order

DRX-CUSTOM-305

Variable-volume cylinder built to specification within a 305 mm outer-diameter envelope. Tell us your required length and capacity and we’ll quote a 250-bar build to suit. Suitable for compact bulk-storage applications where a stock 50-litre cylinder is too large or geometry-constrained.

Volume20 – 40 L

Pressure250 bar

Ø Diameter305 mm

Service Life≤ 200 cycles

Only cylinders marked NLL (No Limited Lifespan) remain in service indefinitely, subject to periodic testing — all others have a defined service life as listed. Tested per the standard listed. Specify gas medium when ordering. H₂ capacity at working pressure / 15 °C; gravimetric % = H₂ mass ÷ (H₂ + cylinder mass). Thread sizes available: M18×1.5, 17E, 25E, 3/4″-16 UNF, 5/8″-18 UNF, M12×1, and others on request. Need a size, pressure, or geometry not listed? Open a custom RFQ.
