FFKM Material Seals

• FFKM Material Seals

Not every FFKM application is an O-ring. This is our moulded FFKM seal range, covering profiles designed for a specific housing rather than for a standard groove. The sectors are the same ones that drive FFKM demand generally: semiconductor, pharmaceutical and chemical, extending into petroleum, automotive, laser plating, battery manufacturing and special equipment production.

Key Benefits

• Moulded profiles designed around your housing rather than a standard groove
• Perfluoroelastomer chemical resistance in a custom geometry
• Tooling designed and built in our own mould workshop
• Suited to sectors where seal failure carries a contamination cost
• Supplied alongside FFKM O-rings on the same order

Problems It Solves

• A seal profile that no catalogue covers and no supplier will tool
• Discontinued proprietary seals with no remaining source
• Chemical attack on seals in demanding process environments
• Dividing O-ring and moulded seal supply across two vendors

Who It Is For

• Equipment builders designing a sealed assembly from scratch
• Plant engineers replacing a discontinued proprietary seal
• Semiconductor and pharmaceutical maintenance teams
• Special equipment manufacturers with non standard sealing geometry

Application Scenarios

• Semiconductor process equipment sealing
• Pharmaceutical process equipment
• Chemical industry plant and transfer systems
• Petroleum and automobile industry applications
• Laser plating battery manufacturing and special equipment production

Where This Is the Right Choice and Where It Is Not

Compared With FFKM O-rings

An O-ring needs a designed groove. A moulded seal suits a housing that already exists and cannot be changed.

Compared With FKM moulded seals

Same geometry, lower chemical range, considerably lower cost. Worth checking before committing to FFKM.

Compared With A machined PTFE part

PTFE holds chemistry but not elastic recovery. Where the joint moves or relaxes, an elastomer seals better.

FFKM O-Rings

FFKM O-rings exist for the applications where every other elastomer has already been ruled out.

FKM and FFKM O-Rings

FKM and FFKM sit at the top of the seal material range and are frequently confused with each other.

Rubber Moulds

We have our own mould manufacturing workshop and experienced structural design engineers, so we can independently design and develop rubber moulds rather than pass the work on.

Y Seals and Y O-Rings

A plain O-ring is not the right answer for every dynamic duty, which is why the Y profile exists.

FFKM or FKM Which One Your Application Actually Needs

FFKM is not simply a better FKM. It is a different commercial decision, and specifying it by reflex wastes money as reliably as under specifying wastes uptime.

Compression Transfer and Injection Moulding for Rubber Parts

The moulding process decides tooling cost, cycle time and how much detail a part can carry. Choosing it is a commercial decision as much as a technical one.

FFKM Material Seals Questions
