If your seal needs to resist acids, solvents, or 260 °C heat, a Kit di anelli di tenuta in PTFE is your go‑to solution. Whether you're in chemical processing or high-pressure environments, this kit offers unmatched reliability.
PTFE O Ring Kits are engineered for extreme resistance to heat, pressure, and corrosive media—far beyond what rubber can handle.
Che cosa è un kit di o-ring in PTFE?
UN Kit di anelli di tenuta in PTFE includes multiple sizes of o rings made from polytetrafluoroethylene—a non-elastic, chemically inert, and high-temperature-resistant material often referred to as Teflon.
These kits are ideal for:
- Chemical plants and refineries
- Food and pharmaceutical processing
- Steam systems and boilers
- Aerospace and precision lab equipment
Compared to rubber kits, PTFE doesn’t degrade in harsh environments.
When should I choose PTFE over rubber o rings?
Choose PTFE if you're dealing with:
- Temperatures above 200°C
- Acids, alkalis, solvents, fuels
- Cleanroom or low-friction sealing
- Long-term static sealing where compression set matters

How does PTFE compare to Viton and NBR o rings?
| Proprietà | PTFE | Vitone (FKM) | NBR (Buna-N) |
|---|---|---|---|
| Temperatura massima | 260°C | 200°C | 120°C |
| Resistenza chimica | ★★★★★ | ★★★★☆ | ★★☆☆☆ |
| Flessibilità | Rigido | Medio | Flessibile |
| Set di compressione | Molto basso | Basso | Medio |
| Adatto al contatto con gli alimenti | SÌ | NO | NO |
For high-temperature flexibility, our Kit O-ring in Viton potrebbe essere la scelta migliore.
Gli O-ring in PTFE sono riutilizzabili?
Yes, PTFE o rings can often be reused—especially in static applications.
But I’ve seen failures due to improper reuse. Here's what to watch for:
- Scratches or deformation
- Over-compression from prior use
- Burrs or sharp edges in the groove
- Thermal expansion fatigue
Use fresh o rings for critical jobs, or inspect thoroughly.
What sizes are included in a PTFE o ring kit?
Our standard kits come pre-packed or can be customized for OEM use:
| Tipo di kit | Dimensioni | Intervallo ID | Sezione trasversale | Confezione |
|---|---|---|---|---|
| 200 pezzi (PTFE) | 20–30 | 3 mm – 48 mm | 1,5–3,5 mm | Plastic box with chart |
| OEM Labeling | Costume | Qualunque | Qualunque | White-label, branded |

Il PTFE è idoneo all'uso alimentare e approvato dalla FDA?
Yes—virgin PTFE complies with:
- FDA 21 CFR 177.1550
- EU 10/2011
- NSF, USP standards on request
This makes PTFE kits suitable for:
- Attrezzature per la lavorazione alimentare
- Dairy pipelines and valves
- Pharmaceutical and biotech
We also offer full documentation for regulatory audits.
What are the best use cases for PTFE o rings?
Based on my experience, top use cases include:
- High-temperature autoclaves
- Chemical transport valves
- UV-exposed sealing (solar, laser systems)
- Aerospace and fuel injection lines
- Static sealing in laboratory equipment
PTFE's strength is long-lasting performance in corrosive or high-heat environments.
Considerazioni finali sui kit O-ring in PTFE
PTFE o rings aren’t for every system—but if you deal with chemicals, steam, or pressure, they’re unmatched in durability and safety.
Don’t gamble with rubber where PTFE is required. Get the right tool for the job.
