AS568 O-Ring Series
Standard AS568 O-rings supplied without tooling cost or tooling lead time. We possess all the moulds for the AS568 size range, so a dash number is a production item
View Details →Custom moulded FKM rubber parts for chemical and high temperature service, with mould design and manufacture in our own workshop rather than subcontracted.

This is FKM outside the sealing catalogue: custom moulded fluoroelastomer parts made to a customer drawing. We provide FKM rubber product processing to order and have our own mould workshop, so the tool for your part is designed and manufactured here rather than subcontracted to a shop that will never run it.
Only values our own records support appear here. Anything we cannot evidence is left out rather than estimated.

| Tooling | Designed and manufactured in our own mould workshop |
| Country of Manufacture | China |
Nitrile is cheaper and adequate for ordinary oil contact. FKM earns its cost when chemistry or temperature exceeds that.
FFKM extends chemical range further at considerably higher cost, and is rarely necessary outside semiconductor and severe chemical service.
Silicone leads on temperature range and flexibility, FKM on chemical and fuel resistance.
FKM and FFKM sit at the top of the seal material range and are frequently confused with each other.
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.
Not every FFKM application is an O-ring.
SBR is the compound to reach for when abrasion resistance and cost matter more than chemical range.
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.
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.
Yes. Custom FKM rubber product processing to customer drawings is exactly what this line is.
Yes, we have our own mould workshop and design and manufacture the tool in house.
Our structural design team can work from the physical part and produce a drawing for your approval.
It depends on the tool and the part. We will tell you at quotation rather than publish a figure that may not apply.
Yes, if agreed in writing before we start.
One working day once we have the drawing, conditions and quantity.
