High-Purity Soft Plastic Tubing
- Manufacturer Equivalent Number:
Tubing without Polyester Braid Reinforcement: 2475
Tubing with Polyester Braid Reinforcement: 2475 I.B. - Flexible
- Compatible with Barbed Tube Fittings
- Soft (Durometer 70A)
- Temperature Range: -90° to 120° F
Designed for high-purity processes, this tubing is made without plasticizers like DEHP that can contaminate the fluid passing through it. It meets USP Class VI specifications for material testing; it is not for use in medical applications. Tubing is clear, so you can monitor flow. It’s also flexible and easily bends around objects.
Tubing with braid reinforcement has extra strength to handle higher pressures than nonreinforced tubing.
