Rubber Seals
O-rings, Y seals and moulded sealing parts in twelve elastomer compounds, tooled to your size rather than substituted from stock.
Browse category →O-rings and moulded rubber seals in twelve compounds, custom moulded rubber parts, rubber bonded to metal, injection moulded plastic parts, the rubber moulds that produce them, and OEM power tools.
Buyers and design engineers at automotive and vehicle part makers, semiconductor and electronics plants, chemical and petroleum processors, printing and paper converting shops, appliance manufacturers, and the trading houses that supply them.
Most seal problems reaching a purchasing desk are not price problems. They are a non standard size nobody will tool, a compound that swells in the actual medium, a mould that will not hold the parting line, or four separate suppliers for one sub assembly. We take those off the desk.
Fourteen engineers across mould structure, rubber formulation, rubber process and power tool design sit in house. More than ten partner factories give capacity without giving up control. The complete AS568 mould set means standard sizes ship without new tooling.

An O-ring is the cheapest part in most assemblies and the most common cause of a warranty return.

We possess all the moulds for the AS568 O-ring size range, which lets us supply standard parts of the series promptly and without a tooling step.

NBR is the working compound for anything that meets oil or fuel at moderate temperature.

EPDM has good weather resistance and unusual versatility, which is why it appears across automotive, electrical and electronic products, daily necessities, sports equipment and mechanised industrial equipment, as well as in wires, cables and high voltage and ultra high voltage insulation materials.

HNBR is the compound we reach for when a nitrile seal has to stay reliable in cold medium service.

FKM and FFKM sit at the top of the seal material range and are frequently confused with each other.
View product →
FFKM O-rings exist for the applications where every other elastomer has already been ruled out.
View product →
Not every FFKM application is an O-ring.
View product →
A plain O-ring is not the right answer for every dynamic duty, which is why the Y profile exists.
View product →
This is FKM outside the sealing catalogue: custom moulded fluoroelastomer parts made to a customer drawing.
View product →
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.
View product →
An O-ring mould decides whether every ring coming off it is the same.
View product →
Bonded rubber to metal parts fail at the interface far more often than in the rubber, and split sourcing is why.
View product →
In printing and converting the roller covering is a process variable rather than a spare part.

SBR is the compound to reach for when abrasion resistance and cost matter more than chemical range.

We have three plastic production suppliers, and we handle the inquiry, the quality control and the delivery supervision ourselves.

A drawing outside AS568 gets answered with the nearest stock item. We cut the tool in our own mould workshop instead.
Seals swell, harden or take a set because the material was picked from stock. Two formula engineers select against your medium and temperature.
A tool cut by a shop that never runs it produces flash and parting line problems nobody owns. We design, build and run our tools.
Rubber, plastic and machined metal bought separately arrive on three lead times. We quote and ship the assembly together.
Fourteen engineers across mould structure, rubber formulation, rubber process and power tool design sit in house. More than ten partner factories give capacity without giving up control. The complete AS568 mould set means standard sizes ship without new tooling.

Two of our senior engineers have at least fifteen years of work experience.

A custom rubber part fails in one of a few predictable places: the structure was never designed for moulding, the tool was cut by someone who will never run it, the compound was chosen from stock, or the first article was approved on a photograph.

Most seal failures that reach a purchasing desk are material decisions made earlier by somebody without the data.

One sub assembly often contains a moulded seal, a plastic housing and a machined metal insert.

Relabelling a catalogue tool is easy and gives a brand nothing to defend.

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.

AS568 is the reason some O-ring quotations come back with no tooling charge and a short lead time, and others do not.

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.

These two compounds cover an enormous share of industrial sealing between them, and they fail in each other's territory. Getting the boundary right removes most avoidable seal problems.
Read the guide →Both, and we prefer to say so. We run our own mould workshop, machining workshop and coating workshop with fourteen engineers in house, and we work with more than ten partner factories in China for development and order capacity.
FKM, FFKM, SIR, EPDM, NBR, SBR, FVMQ, AEM/ACM, HNBR, CR, NR and CSM. Twelve compounds from one supplier.
No. We possess all the moulds for the AS568 O-ring size range, so standard sizes go straight into production.
Yes. Our structural design team can design the product structure from a physical sample and manufacture the mould independently.
Within one working day. Send the drawing, size list or photo by WhatsApp or email.
Yes. We work with three plastic production suppliers under our own inquiry, quality control and delivery supervision, alongside our own rubber production.
Yes, as a separate line with its own engineering team. Our power tool designers have more than fifteen years of experience in the industry.
