PEEK (Polyether Ether Ketone) tubing is widely recognized as a high-performance solution for demanding fluid handling, analytical, and medical applications. Made from ARKPEEK™-1000 resin, this tubing delivers exceptional strength, stability, and chemical resistance-making it a reliable alternative to stainless steel and other metals in extreme environments.
Excellent Pressure Performance of PEEK Tubing
PEEK tubing is engineered to withstand high internal pressure while maintaining dimensional stability. Thanks to its high tensile strength and rigidity, it offers excellent burst-pressure performance and is suitable for high-pressure fluid transfer.
Typical pressure ratings include:
0.003" ID × 0.020" OD: 2,000 psi
0.010" ID × 0.020" OD: 2,000 psi
0.005" ID × 1/16" OD: 5,000 psi
0.020" ID × 1/16" OD: 5,000 psi
0.062" ID × 1/8" OD: 3,000 psi
0.080" ID × 1/8" OD: 3,000 psi
This high-pressure capability makes PEEK tubing ideal for:
HPLC and UHPLC systems
Precision microfluidic channels
Laboratory analytical equipment
High-pressure hydraulic lines
Critical fluid transfer in industrial systems
Because PEEK retains mechanical strength at elevated temperatures-up to 260°C (500°F)-it does not deform or fail during thermal cycling, ensuring consistent safety and performance.
Key Characteristics of ARKPEEK™-1000 PEEK Tubing
1. Exceptional Mechanical Strength
PEEK offers high tensile strength, stiffness, and durability, supporting long-term structural integrity in high-pressure and dynamic applications.
2. Outstanding Chemical Resistance
It withstands exposure to acids, bases, fuels, solvents, and hydrocarbons. This makes it an ideal metal-replacement solution in chemically aggressive environments.
3. High Temperature Stability
PEEK provides continuous service up to 260°C and features a melting point of 343°C—suitable for demanding thermal conditions, sterilization, and industrial processing.
4. Low Friction and Wear Resistance
With natural lubricity and abrasion resistance, PEEK tubing supports smooth, stable fluid flow and long service life.
5. Electrical Insulation
High dielectric strength and electrical resistivity make it suitable for wire insulation, sensors, and electronic components.
