Our PTFE solid plug is engineered for demanding fluid control applications where corrosion resistance and reliability are critical. Made from virgin or virgin-grade PTFE, it offers exceptional chemical inertness, a wide operating temperature range (-200°C to +260°C), and a low friction coefficient that ensures smooth operation without lubrication.

Retail Ready: Standard-sized solid plugs are available in small quantities for immediate shipment—ideal for laboratory equipment, pilot plants, and maintenance replacements. Choose from common diameters and taper angles to fit most industrial and scientific valves.

Custom Solutions: For OEM or specialized applications, we offer full customization—non-standard dimensions, tight tolerances, custom taper angles, and machined features such as slots, threads, or sealing grooves. Low minimum order quantities available for prototyping.

Whether you need a single replacement plug or high-volume production runs, we deliver consistent quality with fast turnaround. Contact us with your specifications.

Excellent Chemical & Physical Properties:
Extremely strong chemical inertness (the core advantage)
PTFE is known as the “plastic king” and hardly reacts with any known strong acids, bases, oxidants, organic solvents, etc.
Tolerant reagents include aqua regia, hydrofluoric acid (HF), hot concentrated sulfuric acid, nitric acid, hydrochloric acid, chromic acid, various organic solvents (such as acetone, benzene, alcohols), etc.
This feature ensures that the stored samples are not contaminated by the container and also guarantees that the container itself is not corroded.
Extremely low leaching and adsorption of metal ions
The surface of PTFE is smooth and dense, and it hardly adsorbs trace elements and components in the sample.
The content of self dissolved metal ions is extremely low, which is crucial for trace analysis (such as ICP-MS, ICP-OES, AA, etc.), effectively avoiding background contamination and ensuring the accuracy of analysis results.
Excellent thermal stability
It can usually be used for a long time within the temperature range of -200 ° C to+260 ° C.
Short term tolerance to higher temperatures (such as 300 ° C) makes it suitable for hydrothermal reactions, high-temperature digestion, or high-temperature sample storage.
Excellent non stickiness and surface smoothness
The surface friction coefficient is extremely low, does not adhere to any substances, is easy to clean and pour out viscous reagents, and there will be no residue.
High purity and good electrical insulation
