Sealing Parts That Match Your Drawing Not Our Catalogue

Twelve seal compounds, our own mould workshop and the complete AS568 mould set, so your size is tooled rather than substituted.

Formula engineers in house means the compound is chosen for your medium and temperature, not for whatever the factory already runs.

Five mould structural engineers design the tool, our own workshop cuts it, and the same team runs the moulding trial, so tooling problems get fixed instead of quoted again.

Seals, moulded rubber, injection moulded plastic and rubber bonded to machined metal, quoted and shipped together instead of chased across four vendors.

Custom O-Rings Rubber Seals and Molded Rubber Parts From One Supplier

What We Make

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.

Who We Serve

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.

What Problem We Solve

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.

Why Buy From Us

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.

Three Product Lines One Engineering Team

Rubber Seals

O-rings, Y seals and moulded sealing parts in twelve elastomer compounds, tooled to your size rather than substituted from stock.

Rubber Products

Custom moulded rubber, rubber bonded to machined metal, industrial rollers, plastic parts and the moulds that produce them.

Power Tools

OEM and custom designed power tools from a team whose designers have more than fifteen years in the tool industry.

Every Part We Make Shown in Full

Twenty products across seals, moulded rubber, moulds, plastics and power tools. Nothing here is a placeholder or a stock photo.

O-Rings

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

AS568 O-Ring Series

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 O-Rings

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

EPDM Seals and EPDM O-Rings

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 O-Rings and HNBR Seals

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

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.

FFKM Material Seals

Not every FFKM application is an O-ring.

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.

FKM Rubber Parts

This is FKM outside the sealing catalogue: custom moulded fluoroelastomer parts made to a customer drawing.

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.

O-Ring Moulds

An O-ring mould decides whether every ring coming off it is the same.

Shock Absorber Bushings and Shocker Bushes

Bonded rubber to metal parts fail at the interface far more often than in the rubber, and split sourcing is why.

Industrial Rubber Rollers

In printing and converting the roller covering is a process variable rather than a spare part.

SBR Rubber Parts and Counterweight Blocks

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

Plastic Parts

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

Industries That Buy Sealing Parts by Drawing

Automotive and Vehicle Parts

Oil and fuel contact that hardens or swells a seal chosen without regard to the medium

Semiconductor and Electronics

Aggressive chemistries and solvents that attack ordinary fluoroelastomer

Chemical and Petroleum Processing

Acids, solvents and hydrocarbons that degrade a general purpose elastomer quickly

Printing and Paper Converting

Feed rollers that glaze or harden and start misfeeding sheets

Home Appliance and Consumer Products

Rubber, plastic and packaging parts of one product sourced from three countries

The Four Reasons a Seal Inquiry Reaches Us

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.

Nobody Will Tool the Size

A drawing outside AS568 gets answered with the nearest stock item. We cut the tool in our own mould workshop instead.

The Compound Is Wrong

Seals swell, harden or take a set because the material was picked from stock. Two formula engineers select against your medium and temperature.

The Mould Will Not Hold

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.

Four Vendors One Assembly

Rubber, plastic and machined metal bought separately arrive on three lead times. We quote and ship the assembly together.

Numbers We Can Actually Stand Behind

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.

Our production floor. Rubber process work and moulding run under our own process engineers rather than being subcontracted blind.

Engineering Team

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

• 5 Rubber Mould Structural Engineers
• 2 Rubber Formula Engineers
• 3 Rubber Process Engineers
• 4 Electric Tool Structural Engineers

In-House Capability

• Own mould manufacturing workshop with independent mould design and development
• Own machining workshop and coating workshop for rubber bonded to metal parts
• The complete AS568 O-ring mould set held in house
• Three plastic production suppliers under our inquiry, quality control and delivery supervision
• More than ten partner factories in China for development and order capacity

How We Control Quality

• Drawing or sample reviewed by our structural design team before quotation
• Compound selected by our formula engineers against the stated service conditions
• First article moulded from the production tool and sent for customer approval
• Production checked against the approved first article before packing
• Delivery supervised by our own staff at partner factories rather than self reported

How the Work Actually Runs

Custom Moulded Rubber From Drawing to Production

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.

Seal Material Selection Across Twelve Compounds

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

Design to Delivery for Mixed Rubber Plastic and Metal Assemblies

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

OEM Power Tool Design and Processing

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

Engineering Guides Written for Buyers

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.

The AS568 O-Ring Size Standard and Why It Saves You Tooling

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

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.

EPDM and NBR Where Each One Belongs and Where It Fails

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.

Questions Buyers Ask Before the First Order

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.
