For OEM equipment builders, pneumatic fittings and tubing should be selected as a connected air-circuit package, not as separate low-cost parts. Start with tube material, outside diameter, port thread, working pressure, machine environment and maintenance access, then confirm the fitting style and tubing grade with the supplier before batch purchasing.
Kailing manufactures pneumatic fittings, tubing, valves, cylinders, actuators and air preparation components, so buyers can submit a single RFQ for the full pneumatic circuit instead of checking each connection item in isolation.
Direct answer for buyers
Choose pneumatic fittings and tubing by matching the tube outside diameter, thread or port standard, working pressure, medium, bend radius, ambient temperature and installation space. If the equipment will be exported, include the destination market and any documentation requirements in the RFQ so the supplier can review material, packaging and labeling needs early.
Selection checklist before asking for a quote
Prepare tube OD and material, fitting type, thread standard, pressure range, air quality, working temperature, quantity, drawing or sample photo, and whether the equipment is prototype, small batch or repeat production. These details help Kailing check pneumatic fittings, tubing and related components together.
When to involve the supplier early
Involve the supplier before freezing the equipment layout when the machine uses compact manifolds, repeated bending, moving axes, mixed metric and inch ports, high cycle pneumatic cylinders, or custom packaging for export. Early review reduces the chance of ordering fittings that connect mechanically but are not ideal for maintenance or assembly.
Internal links for the RFQ path
For related products, review the pneumatic fittings page, pneumatic tubing page, air preparation units, pneumatic cylinders and solenoid valves. When ready, send the tube size, port details, drawings and expected quantity through the RFQ form so the sales engineer can match the circuit.
| Parameter | Value |
|---|---|
| Tube size | Confirm outside diameter, inside diameter if relevant, and metric or inch standard. |
| Tube material | PU, PA, PE or other material depending on flexibility, pressure and environment. |
| Connection type | Push-in fitting, metal fitting, quick coupling, silencer or special connector. |
| Thread / port | Provide thread standard, port size, sealing method and any drawing reference. |
| Working condition | Air pressure, temperature, movement, vibration, oil mist and installation space. |
| RFQ package | Share drawings, photos, quantity, target delivery time and destination market. |
Frequently Asked Questions
- FAQ Can buyers request pneumatic fittings without a complete model number?
Yes. Send photos, tube diameter, thread size, application pressure, quantity and equipment context. Kailing can review the likely fitting style and ask follow-up questions when needed. - FAQ Should tubing and fittings be quoted together?
For OEM equipment, quoting them together is usually better because tube material, tube diameter, bend radius and connector style affect installation and maintenance. - FAQ What if the machine also needs valves or cylinders?
Include the valve, cylinder, actuator or air preparation requirement in the same RFQ. Kailing can review the pneumatic circuit as a package rather than isolated parts.
