Did you know that PTFE threaded plugs can operate in environments where many metal plugs fail?

Thanks to PTFE's exceptional chemical resistance, these plugs can handle strong acids, alkalis, solvents, salt spray, and even seawater without rusting or corroding.

They also perform across a remarkably wide temperature range, from -80°C to 260°C, while maintaining reliable sealing performance.

A useful installation tip: PTFE threaded plugs don't require excessive tightening. In many tapered thread applications, the material itself helps create an effective seal, reducing the need for additional sealing tape.

Small component. Big impact on system reliability.

Do you know the difference between ePTFE tube and PTFE Tube?

expanded PTFE (ePTFE) tubes, hydrophobic tube, are porous tubes made by expanding PTFE.They keep PTFE’s chemical and heat resistance, while adding breathability, flexibility, light weight, and biocompatibility.

Let us know the unique Features of ePTFE Tubes
➡️3D microporous network, breathable yet waterproof—lets gas through but blocks liquid water.
➡️Chemically resistant, heat-resistant, biocompatible, low-friction, flexible and bendable.
➡️Varies with porosity, typically 0.6–1.2 g/cm³ (common: 0.8–1.0 g/cm³).
➡️Pressure rating Depends on wall thickness, diameter, and porosity; generally 0.5–3 MPa, with thick-wall or optimized types exceeding 5 MPa (check product specs).

Color stripes on PFA tubing are not just for appearance.

In complex piping systems, striped PFA tubing helps engineers and operators quickly identify different fluid channels, improving installation efficiency and reducing maintenance errors.

Compared with labels or external markings, color stripes are more durable and remain visible even in harsh chemical environments.

Combined with the excellent performance of PFA material, striped tubing offers:
✔ Excellent corrosion resistance
✔ High purity for sensitive applications
✔ High temperature resistance(-200 to 260℃）
✔ Low extractables and smooth flow performance

An ideal solution for semiconductor, pharmaceutical, and chemical industries.

PTFE bolts and nuts offer excellent chemical resistance and insulation performance, but creep is an important factor in long-term applications.

Key factors affecting PTFE fastener creep:
• Higher temperature = faster creep
• Excessive tightening torque increases deformation
• Long-term loading can lead to loosening
• Pure PTFE creeps more than filled PTFE
• Thin bolts and long studs deform more easily
• Smooth contact surfaces help reduce stress concentration
• High temperature + pressure accelerate creep

Choosing the right PTFE material and proper installation conditions can greatly improve fastening stability and service life.
