Oil-free PTFE braided packing is ideally suited for applications such as food processing, pharmaceuticals, oxygen transport, and cleanrooms, as it eliminates risks of contamination and explosion.
It withstands temperatures ranging from -180°C to +200°C, pressures up to 200 bar (static) / 80 bar (dynamic), and linear speeds up to 20 m/s (static) / 12 m/s (dynamic); it is compatible with a pH range of 0–14 and offers universal chemical resistance.
Oil-free PTFE packing is braided from pure PTFE fibers with no added lubricants — no oil, no grease, no silicone, no graphite. PTFE itself provides the lowest coefficient of friction of any solid material (0.05-0.20), so no external lubrication is required.
Why it matters: Standard PTFE packing is impregnated with lubricants to reduce friction. But in critical services, these lubricants can:
Leach into food or pharmaceutical products → product loss, FDA violations
React with oxygen → fire or explosion risk
Outgas in cleanroom or semiconductor applications → product contamination
Contaminate sensitive chemical processes → batch failure
Oil-Free PTFE Braided Packing eliminates all these risks.

The Consequence of Choosing Wrong |
|
Oil leaches into food/pharma |
No oil — zero contamination risk |
$10,000+ in product loss + FDA fines |
|
Lubricants react with oxygen |
Oil-free design — oxygen safe |
Explosion risk — equipment damage + safety incident |
|
Lubricants outgas in cleanrooms |
No lubricants — no outgassing |

Client: Large food processing company handling fruit concentrates (mid-size US food manufacturer)
Challenge: Standard lubricated PTFE packing risked lubricant migration into food products — FDA violation risk and potential product loss.
Solution: Supplied Oil-Free PTFE Braided Packing, no added lubricants. FDA-compliant material. Full documentation provided.
Result: FDA compliance achieved. Zero contamination events. Packing performed reliably for over 12 months. $50,000/year in potential product loss avoided.
Client: Oxygen generation facility
Challenge: Standard PTFE packing contained oil — oil + oxygen under pressure = explosion risk. Any oil-contaminated packing was unacceptable.
Solution: Installed oil-free PTFE packing — no oil, no grease. Oxygen service approved. Certification provided.
Result: Safe operation achieved. No incidents. Inspection passed. Zero safety violations.

A: PTFE packing with no added oil, grease, or silicone lubricants. Pure PTFE is self-lubricating, no external lubricants are needed. Use it when contamination is a risk.
When to use it: Food processing, pharmaceuticals, oxygen service, cleanrooms, semiconductor manufacturing, sensitive chemical processes.
When NOT to use it: High-speed dynamic service (above 12 m/s), lubricated PTFE handles higher speeds better. Abrasive media, use aramid/PTFE. High temperature above +200°C, use carbon fiber.
The cost of choosing wrong: Standard PTFE may cost less upfront, but in food/pharma, one product contamination event can cost $10,000+. In oxygen service, the cost is far higher.
A: The real cost is not the packing, it is the risk. Standard PTFE costs less upfront, but contains oil, silicone, or graphite lubricants.
The true cost comparison: Oil-free PTFE costs more upfront, but eliminates contamination risk, product loss, and safety incidents.
Quick rule:
Food, pharma, oxygen, cleanroom → Oil-free PTFE (one avoided event pays for the packing many times over).
General industry, no purity requirements → Standard PTFE (lower cost).
A: Temperature: -180°C to +200°C.
Pressure: up to 200 bar (static), up to 80 bar (dynamic).
Speed: up to 20 m/s (static), up to 12 m/s (dynamic).
Chemical: pH 0-14, universal resistance.
Three common mistakes:
(1) Using oil-free at high speed — above 12 m/s, friction heat builds up. Use lubricated PTFE or carbon fiber.
(2) Using oil-free in abrasive service — PTFE is soft; wear out fast. Use aramid/PTFE.
(3) Over-tightening — PTFE is soft; excessive compression causes cold flow and leakage. Use a torque wrench.
