Pneumatics and Hydraulics
Pneumatics and hydraulics are the muscles of every production and process plant. Cylinders, valves, fittings, air preparation and hoses interlock so closely that a single mis-dimensioned component slows the whole chain.

Buying Pneumatics and Hydraulics — what matters in the selection
Pneumatics and hydraulics are the muscles of every production and process plant. Cylinders, valves, fittings, air preparation and hoses interlock so closely that a single mis-dimensioned component slows the whole chain.
shukchok carries both the actuating elements and the unglamorous parts that actually cause the failure: push-in fittings, one-way flow controls, service units and seal kits. Every item states thread size and operating pressure.
Particularly relevant for maintenance teams: we deliberately list individual components, not just complete assemblies. Anyone who only needs the rod seal should not have to replace the entire cylinder.
Selection criteria
Distinguish operating pressure from burst pressure
The permissible operating pressure is the design figure, not the burst pressure. Under pulsating load the operating pressure should stay well below the nominal value.
Check the thread precisely
G (BSPP), R (BSPT) and NPT look similar and are not compatible. The wrong thread appears to seal and then pulls out under load.
Air quality to ISO 8573-1
Valves and cylinders answer moist or oily compressed air with corrosion and sticking seals. Filters, water separators and dryers are part of the design, not an accessory.
Hose inner diameter, not outer
Flow rate depends on the inner diameter. For push-in fittings the outer diameter is what counts — state both when ordering.
Frequently asked questions
Does an 8 mm push-in fitting match my hose?
Push-in fittings are designated by hose outer diameter. An 8 mm fitting suits a hose with 8 mm outer diameter regardless of wall thickness. The inner diameter determines the achievable flow rate.
Can I use pneumatic components in a hydraulic circuit?
No. Hydraulics work at a multiple of the pressure and with oil-resistant materials. Pneumatic components are rated for neither.
Can I order seal kits instead of complete cylinders?
Wherever the manufacturer offers seal kits we list them separately. Tell us the cylinder type and bore — a matching kit can usually be sourced even for older series.
Can I order pneumatics and Hydraulics on account?
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.
How quickly are pneumatics and Hydraulics delivered?
14 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.
Do I get technical data sheets for pneumatics and Hydraulics?
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.
Who is my contractual partner when I order?
It is stated on the line. For own goods shukchok is the seller and contracting party; where a named supplier lists the product, the supplier is, and we invoice in their name and for their account (clause 2 of the terms). The ordering process and your contact in support are the same either way.
Can I return pneumatics and Hydraulics?
Unused stock items can be returned within the statutory and contractual rules. Items made or configured to customer specification are excluded from return. Please register a return in advance so we can allocate the process.
