🔍 Purpose and Performance

FOP is a high-performance one-way sealing ring composed of a stainless steel V-type (or O-type) spring and a filled PTFE U-ring. It is specifically engineered for slow to medium-speed reciprocating or slow-speed rotating motion, making it ideal for hydraulic cylinders and air cylinders.

From vacuum to zero pressure and ultra-high pressure, the FOP seal ensures reliable performance. It is particularly effective for low-viscosity media and hot melt adhesive media. For industries like pharmaceuticals and food processing, the spring cavity can be filled with silicone to prevent contaminants and withstand harsh cleaning agents.

✨ Key Features

Versatile application for both reciprocating and rotating motions.
Excellent compatibility with most fluids and aggressive chemicals.
Extremely small friction coefficient to eliminate crawling issues.
Superior anti-corrosion properties and high dimensional stability.
Non-contaminating design suitable for food and pharmaceutical liquids.
Withstands rapid and extreme temperature fluctuations.

❓ Frequently Asked Questions

What media is the FOP seal compatible with?

The FOP seal is compatible with almost all liquids, chemicals, and gases due to its PTFE construction and stainless steel spring.

Can this seal be used in food processing?

Yes, it will not contaminate food or pharmaceutical liquids. For high hygiene requirements, the spring cavity can be filled with silicone to prevent contaminant buildup.

What is the maximum pressure this seal can handle?

It can handle static vacuum up to 120Mpa and dynamic vacuum up to 45Mpa.

How does the spring improve sealing?

The V-type or O-type spring provides constant tension to the PTFE U-ring, ensuring a reliable seal even at zero pressure or vacuum conditions.

What is the typical lead time for an order?

The standard delivery time is between 7 to 15 working days depending on the order quantity.

Is the FOP seal suitable for high-speed rotation?

It is best suited for slow-speed rotation (≤2.5m/s) or reciprocating motion (up to 15m/s).
