Piping and fittings decide whether a plant stays tight. The parts themselves are unspectacular — faults almost always arise at the interface: wrong thread, unsuitable material, over-tightened fitting.

shukchok carries tubes, fittings, compression couplings, adapters and mounts for process and analytical technology. Material, nominal size and connection type are stated per item.
In gas analysis material choice counts twice: stainless steel and PTFE behave completely differently towards moist sample gas than galvanised steel, which can falsify readings through adsorption.
Stainless 1.4571 for aggressive media and sample gases, PTFE for highly corrosive applications and low adsorption, copper and brass for compressed air and water.
Parallel (G/BSPP) seals on a sealing face, tapered (R/BSPT, NPT) on the thread itself. Mixing the two gives a joint that appears to hold and fails under pressure.
Nominal size is a designation, not a dimension. Pressure-drop calculations need the actual inner diameter including wall thickness.
Compression fittings are tightened by turns from finger-tight, not by feel. Over-tightened ferrules cut into the tube and start leaking.
Not advisable. Zinc reacts with moist and acidic sample gases, which falsifies readings and causes deposits over time. Stainless steel or PTFE is the standard in analytical technology.
A G thread is parallel — the diameter stays constant along its length. NPT is tapered and visibly narrows. When in doubt use a thread gauge rather than trial and error; a wrongly started thread damages the mating part.
Cut-to-length is available through our suppliers. State length, tolerance and required edge treatment — for analytical lines also whether deburred and flushed delivery is needed.
Card payment, Apple Pay and Google Pay are available immediately. Purchase on account and prepayment by bank transfer are in preparation for business customers and will be available shortly. If a card declines a larger amount, please contact us — we handle those orders individually.
13 items in this category are currently listed as available. There is no blanket delivery time — it depends on the item, and stock goods, made-to-order parts and special versions differ considerably. The figure that applies is stated on the product page.
Yes. Data sheets, dimensional drawings and manuals are — where provided by the manufacturer — filed under “Downloads” on each product and accessible without an account. If a document is missing we will supply it on request.
