High flexibility in pipe construction for compact piping

The pressure-resistant reinforcement layer is made from synthetic fibers, providing high fatigue resistance against repeated bending.

The inner tube incorporates materials with extremely low metal ion elution.

Fully integrated construction ensures perfect adhesion between layers

Available type with intermediary layer (3-layer structure)

Drawing on special fluoropolymer tube-forming technologies, Junkosha has achieved ultraviolet permeability rivaling quartz glass.

These tubes are suitable for use in place of quartz glass, which pose the risk of breaking, shattering, and other safety issues.

Excellent heat and cold resistance.

Temperature range for continuous no-load use 
PFA: -65 to +260°C 
FEP: -65 to +200°C

Inactive in regard to almost chemicals or solvents.

Excellent resistance to weather and it does not change with age.

Almost nothing sticks to it, and even if it does, it is easily removed.

Flame-resistant.

Excellent electrical characteristics.

No risk of elution of poisonous substances.

Fluoropolymer tube that displays good barrier performance.

Hybrid type tube which is laminated by PFA for inner layer and barrier fluoropolymer for outer layer.

The inner, wetted layer using PFA for semiconductors offers high quality in non viscous properties, heat resistance.

Barrier fluoropolymer from good barriers against hydrochloric acid, sulfuric acid, and ammonia.

Retard acid penetration compared to a conventional tube.

The adverse effect on the ambient surrounding is decreased.

Retains its transparency so that liquid flowing through it can be seen for extended periods.

Mechanical properties equal those of conventional PFA tubes.

All manufacturing operations are managed to ensure clean practices, from materials supply to molding/packaging.

Double layered structure improved tubes flexibility, kink-proof property and abrasion resistance, which were impossible for fluoropolymer tube.

Excellent fluid repellency by using specific fluoropolymer for inner layer.

Single molding process generates the complete adhered tube, and no gaps between each layer.

For UP1 series, there are special fittings, "US2", which has the twist preventing mechanism.

Unites polyurethane pneumatic tube with wires for electric signals.

Air and electric signal circuit can use the same line. In coil and flat form, it has excellent flexibility and expandability.

The built-in wires are JUNFLON® wires with flexural resistance, the product of technology acquired in developing special wires for computers

Unites polyurethane pneumatic tube with shielded cables that cut out noise.

Air and electric signal circuit can use the same line. In coil or flat form, it has excellent flexibility and expandability.

The built-in shielded cables are JUNFLON® shielding cables with excellent flexural resistance, the product of technology acquired in developing special wires and cables for computers.

Polyurethane tube in coil or flat form, ideal for centralized piping in expanding parts.

Excellent mechanical strength, especially abrasion resistance.

Flexibility highly impact resilient.

Excellent flexibility and wear resistance.

Reinforced with spiral thread, it has excellence resistance to pressure.

Bundling together quickly and easily.

Wires or tubes can be pulled out at any point, and wiring and tubing assembly are secure and accurate.

With excellent wear resistance and flexibility, it is suitable for acute-angle corners, etc.

As it is highly resilient and does not break, it can be used any number of times.

Two layer structure tube with the outer layer of flame-resisting. The outer layer prevented sparks of spot welding.

Superior flexibility and waterproof.
