If your seal needs to resist acids, solvents, or 260 °C heat, a PTFE aŭ ringa ilaro 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.
Kio estas PTFE-o-ringa ilaro?
A PTFE aŭ ringa ilaro includes multiple sizes of o rings made from polytetrafluoroethylene—a non-elastic, chemically inert, and high-temperature-resistant material often referred to as Teflono.
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?
Proprieto | PTFE | Vitono (FKM) | NBR (Buna-N) |
---|---|---|---|
Maksimuma Temp | 260°C | 200°C | 120°C |
Kemia Rezisto | ★★★★★ | ★★★★☆ | ★★☆☆☆ |
Fleksebleco | Rigida | Meza | Fleksebla |
Kunprema Aro | Tre Malalta | Malalta | Meza |
Manĝaĵo Kontakto Sekura | Jes | Ne | Ne |
For high-temperature flexibility, our Viton O Ring Kit eble estos la pli bona elekto.
Ĉu PTFE aŭ ringoj estas reuzeblaj?
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:
Ilaro Tipo | Grandecoj | ID Gamo | Transversa Sekco | Pakado |
---|---|---|---|---|
200 PCS (PTFE) | 20–30 | 3mm - 48mm | 1,5–3,5 mm | Plastic box with chart |
OEM Labeling | Kutimo | Ajna | Ajna | White-label, branded |

Ĉu PTFE-manĝa grado kaj FDA estas aprobita?
Yes—virgin PTFE complies with:
- FDA 21 CFR 177.1550
- EU 10/2011
- NSF, USP standards on request
This makes PTFE kits suitable for:
- Ekipaĵo pri nutraĵo
- 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.
Finaj Pensoj pri PTFE O Ringaj Ilaroj
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.
