Stable fep/ pfa tubing sizes control:
Suniu factory use Laser Diameter Measurement(abbr. LDM) to monitor outer diameters of fep tubing & pfa tubing, besides, pin guage is used to test inner diameter. LDM continuously measures tubing OD (outer diameter) during production. It also tells ovality in LDM display, with high accuracy to keep OD remain within setted specification. The LDM will alarms if size exceed setted specification.
Suniu key advantage:
Suniu factory is equiped with advanced fep tubing extruder that many parts are imported from Japan. So our pfa/fep tubing are more flexible, with stable accurate sizes. We buy Gas Chromatography to analyze chemical components and cleaness of fep tubing.
Suniu FEP Tubing passes F.D.A. 21 CFR 177.1550:

FEP Tubing property:
Suniu Co.,Ltd offers a wide range of FEP Tubing sizes as well as the ability to produce custom Metric FEP Tubing. FEP Tubing is very useful in applications where clarity and chemical resistance are key. Teflon FEP Tubing is also key for applications where long runs of tubing are needed in the larger internal diameters. Fluid Transfer and Chemical Processing are two industries that greatly benefit from the use of clear FEP Tubing.
FEP Tubing Characteristics :
Ø FEP Tubing offers the best in chemical and electrical product protection.
Ø FEP temperature range : -454° F (–270° C) to 400° F (204° C)
Ø Teflon FEP Tubing is chemically inert & Self lubricating.
Ø FEP Tubing has excellent UV pass through.
FEP Tubing Certification:
Ø Resin is F.D.A.-compliant (21 CFR 177.1550)
Ø USP Class VI
