PTFE O-ringsæt: Den ultimative tætning til kemikalier, varme og tryk

PTFE O-ringsæt: Den ultimative tætning til kemikalier, varme og tryk

If your seal needs to resist acids, solvents, or 260 °C heat, a PTFE eller ringsæt 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.

Hvad er et PTFE o-ringsæt?

EN PTFE eller ringsæt 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?

Ejendom PTFE Viton (FKM) NBR (Buna-N)
Max Temp 260°C 200°C 120°C
Kemisk resistens ★★★★★ ★★★★☆ ★★☆☆☆
Fleksibilitet Stiv Medium Fleksibel
Kompressionssæt Meget lav Lav Medium
Fødevarekontaktsikker Ja Ingen Ingen

For high-temperature flexibility, our Viton O-ringsæt kan være det bedre valg.

Er PTFE o-ringe genanvendelige?

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:

Sættype Størrelser ID rækkevidde Tværsnit Emballage
200 STK (PTFE) 20-30 3 mm – 48 mm 1,5-3,5 mm Plastic box with chart
OEM Labeling Skik Enhver Enhver White-label, branded

Er PTFE fødevaregodkendt og FDA godkendt?

Yes—virgin PTFE complies with:

  • FDA 21 CFR 177.1550
  • EU 10/2011
  • NSF, USP standards on request

This makes PTFE kits suitable for:

  • Udstyr til fødevareforarbejdning
  • 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.

Endelige tanker om PTFE O-ringsæt

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.

Folk spørger også

1. Kan jeg bruge PTFE o-ringe i hydrauliske systemer?
Yes—for static applications. Not ideal for dynamic seals unless paired with backup rings.
2. Er PTFE o-ringe bedre end Viton?
Yes for chemical resistance; Viton is more flexible for dynamic seals.
3. Kræver PTFE o-ringe smøring?
No. PTFE is naturally self-lubricating.
4. Kan PTFE o-ringe håndtere damp?
Yes—they’re excellent in autoclaves and high-pressure steam environments.
5. Are your PTFE kits FDA or USP compliant?
Yes, on request. We offer virgin and medical-grade PTFE kits.
6. Tilbyder du blandede sæt med PTFE og gummi?
Yes. These are perfect for multi-purpose sealing and repair work.
7. Hvor længe holder PTFE o-ringe?
Properly stored, they last up to 10 years—sometimes more in static use.
8. Can I customize packaging and logos?
Yes, we support custom printing and private label kits from just 100 sets.
