Priminox Overseas is the official distributor of HOKE sampling cylinders in Mumbai, India. These cylinders capture, hold, and transport pressurised liquid and gas samples for laboratory analysis in refineries, petrochemical plants, and chemical processing units. We stock both spun and formed sampling cylinders in 316 Stainless Steel, MONEL, and Hastelloy, with capacities from 10 mL up to 3.5 gallons at our ISO 9001 and ISO 14001 certified Mumbai warehouse. Standard cylinders carry a 1,800 psig (124 bar) operating pressure rating, pass hydrostatic proof testing at 3,000 psig (206 bar), and meet US DOT 3E and 3A specifications along with EU TPED 2010/35/EU compliance.
We supply the full HOKE sampling cylinder programme, covering spun DOT-rated cylinders, formed one-piece cylinders, cylinder valves, safety relief devices, and the accessories needed to transport pressurised samples safely.
Send your HOKE part number, capacity, pressure, and media, and we will come back with the matching model, stock position, and price.
HOKE sampling cylinders carry pressurised process samples for laboratory analysis across hydrocarbon, chemical, and gas processing operations:

The maximum operating pressure is 1,800 psig (124 bar) for standard spun and formed cylinders. Formed cylinders rated up to 5,000 psig are available as a special order from the factory.
HOKE Sampling Cylinders cover capacities from 10 mL up to 3.5 gallons. The spun DOT range starts at 75 cc and tops out at 3,785 cc (1 gallon).
Spun cylinders are made in 316 Stainless Steel only, in fixed DOT 3E and 3A sizes from 75 cc to 1 gallon. Formed cylinders are drawn from one-piece tubing in 316 SS, MONEL, or Hastelloy, in single or double-ended configurations from 10 mL to 3.5 gallons, with higher pressure options on request.
Standard-formed cylinders ship with internal sandblasting. Optional treatments include FEP lining (suffix TL), Sulfinert coating (suffix SLF), Silcosteel, and Restek, available on most sizes on request.
The 1700 Series handles 1/4" and 3/8" NPT cylinders at up to 6,000 psig. The 2400 Series fits 1/2" cylinders at 5,000 psig and accepts an integral rupture disc or spring relief. The 3700/3800 Series covers 1/8" through 3/8" NPT cylinders at 5,000 psig with orifices from 0.060" to 0.219".
Yes, dip tubes ship in 10%, 20%, and 30% outages, giving filled capacities of 90%, 80%, and 70%, respectively. The dip tube must be welded to a fitting, valve, or relief device, and the cylinder model or capacity needs to be specified on the order.
Yes. Formed cylinders are available in alloys beyond 316 SS, MONEL, and Hastelloy on factory quotation, and pressure ratings above 1,800 psig (up to 5,000 psig) ship as special orders. ASME-tested cylinders are also available when the maximum pressure and temperature are specified at the time of enquiry.
Beyond instrumentation valves, Priminox stocks the complete HOKE product family — fittings, actuators, quick couplings and sampling solutions.
