Chemical and petroleum plants replace seals on a schedule, and every unplanned replacement is downtime. The compound, not the price, sets that interval.
Industry Pain Points
- Acids, solvents and hydrocarbons that degrade a general purpose elastomer quickly
- High temperature service where the seal loses elasticity before it loses shape
- Seals for reactors, mixers and transfer systems where a leak stops the line
- Packer and screw pump service with cold medium requirements
What Buyers Here Need
- FKM for petroleum products, hydraulic fluids and acidic compounds
- FFKM where the chemistry is close to universal aggression
- HNBR for cold medium duty in packer and screw pumps
- Consistent supply so a maintenance schedule can be planned
What We Supply Into This Sector
FKM and FFKM O-Rings
FKM and FFKM sit at the top of the seal material range and are frequently confused with each other.
FFKM O-Rings
FFKM O-rings exist for the applications where every other elastomer has already been ruled out.
FKM Rubber Parts
This is FKM outside the sealing catalogue: custom moulded fluoroelastomer parts made to a customer drawing.
HNBR O-Rings and HNBR Seals
HNBR is the compound we reach for when a nitrile seal has to stay reliable in cold medium service.
O-Rings
An O-ring is the cheapest part in most assemblies and the most common cause of a warranty return.
Typical Application Scenarios
- Reactor, mixer and transfer system seals
- Petroleum machinery and mining machinery sealing
- Hydraulic and pneumatic circuits handling aggressive fluids
- Packer and screw pump seals
Delivery Capability
- One supplier across FKM, FFKM, HNBR and the rest of the schedule
- Repeatable formulation on repeat orders
- Custom profiles tooled rather than approximated
From Inquiry to Series Release
- List the media, concentrations where known, and the temperature range

Guides for This Sector
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.
How to Choose a Rubber Seal Material in Six Questions
Six questions decide almost every seal material choice. Answer them before you ask for a price, and the quotation you get back will be worth comparing.
Chemical and Petroleum Processing Questions
Yes. Send the media, the temperature range and the pressure, and our formula engineers will propose compounds and explain the reasoning.
Both. Y seals and Y O-rings in hole and shaft types are a standard part of our range, and other profiles are tooled in our mould workshop.
Repeat orders run from the same formulation and the same tool. Our process engineers are in house, so the recipe does not change silently.
One working day for a first quotation once we have the size, the compound or the media, and the quantity.
Sourcing for Chemical and Petroleum Processing
Send the drawing, the medium and the temperature range. We will come back with compounds and a price within one working day.
