What Are Pneumatic Components?
Pneumatic systems tend to fail at the interfaces — a fitting thread that doesn't match, a valve with the wrong port size, a cylinder whose mounting style differs from the one it replaces. The components themselves are largely commodity; specifying them correctly is not.
ChatMRO holds over 1.3 million pneumatic parts with full dimensional data: bore, stroke, rod thread, port size, mounting style, flow coefficient and operating pressure. That makes "2 inch bore, 6 inch stroke, double acting, NFPA mount" a complete, resolvable query rather than a starting point for a search.
Because the same catalogue covers SMC, Festo, Parker, Norgren and Numatics side by side, cross-referencing between brands is direct — useful when a preferred supplier is on allocation and a line is waiting on a single valve.

| Spec | What It Means | Why It Matters |
|---|---|---|
| Bore & Stroke | The cylinder's internal diameter and the length of piston travel | Together they determine the force and range of motion a cylinder can deliver |
| Acting Type | Single-acting or double-acting cylinder operation | Determines whether air power is needed to retract as well as extend |
| Mounting Style | The physical mounting configuration, e.g. NFPA, ISO, tie rod | A mismatch means the cylinder cannot be installed in the existing mounting points |
| Port Size & Thread | The thread size and standard of the air connection ports | Must match the fittings and tubing already in the pneumatic circuit |
| Operating Pressure | The maximum and typical working pressure the component is rated for | Running above rated pressure risks component failure and safety hazards |

Applications
Where Pneumatic Components Get Used
The same component behaves differently by sector, because the duty cycle, the environment and the paperwork all change.
Packaging & filling lines
High cycle rates with short strokes, where compact cylinders, manifold-mounted valve banks and reliable end-of-stroke sensing matter more than raw force.
Automotive assembly & robotics
Clamping, indexing and end-of-arm tooling with vacuum grippers, generally on ISO 15552 cylinders and networked valve islands.
Food & beverage processing
Washdown-rated actuators with stainless or coated bodies and seals compatible with cleaning chemistry, plus non-lubricated air to avoid oil carry-over near product.
Plastics & injection moulding
Core pulls, ejection and part handling in a hot environment that derates tubing pressure ratings and shortens seal life.
Material handling & conveying
Diverters, stops and pushers over long distribution runs where pressure drop in the piping, not the valve, usually limits performance.
Pharmaceutical & cleanroom
Oil-free air with coalescing filtration and a specified pressure dew point, using non-lube components throughout.
Machine tools & workholding
Pneumatic clamping, tool changers and chip blow-off, often combined with air gauging that demands clean dry air at closely regulated pressure.
Mining, quarrying & heavy industry
Air tools, actuators and pilot circuits in dusty, wet conditions where filtration and drainage dominate reliability.

FAQ
Pneumatic Components Questions, Answered
Can ChatMRO cross-reference SMC to Festo or Parker?
Yes. Give it the part number you have and ask for equivalents; ChatMRO returns comparable parts from other manufacturers with bore, stroke, mounting and port differences called out explicitly.
I only have the cylinder dimensions, not a part number. Can you help?
That is the normal case. Describe bore, stroke, acting type and mounting and ChatMRO shortlists the matches, asking only for the details still needed to confirm.
Do you supply repair kits and seals?
Seal kits, rod glands and service parts are indexed alongside the assemblies. Ask for the kit that fits a specific cylinder and ChatMRO resolves it from the parent part number.
Can I get a quote for a full machine build?
Yes. Submit the whole bill of materials in one request — cylinders, valves, fittings and tubing — and it is priced and shipped as a single consolidated order.
Is metric and imperial tubing both available?
Both, in nylon, polyurethane and PTFE, with matching push-to-connect fittings in NPT, BSPP and metric threads.
