Technical moulded rubber parts to drawing, in small batches too
JRT Elastomertec makes technical moulded rubber parts to your drawing or specification. They are pressed in our own plant, in small batches as well as in series.
Soft rubber moulded parts
Soft rubber moulded parts include adapters, seals and flat gaskets, flange sleeves, couplings, O-rings in special sizes, pump housings and valve inserts, as well as plugs and bushes.

Seals and flat gaskets
We also make seals as spare parts for classic cars and racing cars.
O-rings in special sizes
An O-ring counts as a special size when its combination of inside diameter and cross-section is not in the standard size series.
Couplings, flange sleeves and adapters
Couplings join two pipe ends, adapters connect different types of connection.
Valve inserts and pump housings
Rubber-to-metal bonds with steel and brass
In a rubber-to-metal bond the elastomer is bonded firmly to a metal part during vulcanisation. JRT Elastomertec makes rubber-to-metal bonds with steel and brass for plant engineering, building and electrical engineering, vehicle construction, mechanical engineering and vibration engineering.

How a moulded rubber part is made
Compound matched to the intended use
Selected compounders put the compound together to suit the intended use of the moulded part.
Pressing in our own plant
Moulded parts are vulcanised in a compression moulding process, separately from hoses and bends. Besides machine moulding and pressing, hand fabrication is possible. Moulded parts can be marked by colour or permanently by embossing, and packaging follows your specification on request.

Moulded rubber parts in small batches and series
We make moulded parts as single parts, in small batches and in series, for example for prototypes or as spare parts. Our moulded parts go to plant engineering, renewable energy, motorsport and classic cars, among others.
Three steps to a moulded rubber part
- 01
Send the drawing or specification, together with quantity, material, medium, operating pressure and operating temperature.
- 02
We advise on the design and check where the part can be optimised on the basis of your drawing.
- 03
You usually approve the initial sample on the basis of an initial sample inspection report with inspection certificate 3.1 to DIN EN 10204, supplemented by a 3D measurement report on request. We then make the agreed quantity.
FAQ: moulded rubber parts
What types of moulded parts are there?
Moulded parts in soft rubber such as seals, couplings, plugs, bushes or O-rings in special sizes, and moulded parts as rubber-to-metal bonds.
From what quantity do you make moulded rubber parts?
From single parts through small batches to series production.
Do you make O-rings in special sizes?
Yes, O-rings in special sizes are among our soft rubber moulded parts.
Which metals do you bond to rubber?
Steel and brass.
Where are the moulded parts made?
In our own plant. The tools are built by proven regional partners.
