Air line routing category
Tubing defines the air path between FRL units, valves, actuators, fittings, and workstations.

Category buying guide
Pneumatic tubing looks simple, but it affects pressure drop, routing quality, installation time, maintenance visibility, and fitting compatibility.
Before RFQ
Series comparison
The most useful tubing inquiry includes outside diameter, inside diameter when known, material, color, coil length, working pressure, temperature range, bend radius, and matching fittings.

02 / Stable pressure route

03 / Model-by-model route
Choose by air-line job
Pick the closest tubing or air blow use case, then confirm material, tube OD/ID, length, color, pressure, bend radius, or nozzle details before RFQ.
Review function, size, pressure, mounting, and inquiry data for Pneumatic Tubing and Air Line Accessories.
PU tubing with confirmed OD, ID, color, coil length, and matching connector family.
Recoil tube can keep the air line available without leaving loose hose across the operator station.
UC recoil polyurethane tubing with working length, retracted length, connector ends, and pressure rating.
PA6 and PA12 tubing help when a circuit needs a stiffer line, higher pressure margin, or colder environment review.
PA6 or PA12 nylon tubing selected by OD/ID, pressure, temperature, bend radius, and color.
Air blow gun selection depends on body material, inlet thread, nozzle style, barrel length, and whether airflow needs adjustment.
AD Series air blow gun route with nozzle, inlet, pressure, and workstation details confirmed.
Common air-line uses

PU and nylon tubing carry compressed air from FRL units and valve manifolds to cylinders, grippers, ejectors, blow-off points, and sensors.

Recoil polyurethane tubing and air blow guns support flexible working areas where operators need clean movement and controlled compressed-air output.

PA6 and PA12 nylon tubing help when machine lines need stronger dimensional stability, higher pressure margin, or cold-area flexibility.
