Read More About Our Seating and Sealing Washers
Seals and washers play a crucial role in the correct running of high-pressure systems. For instance; with every new injector kit you will have a soft copper washer – actually, it’s a high-pressure seal.
In high-pressure diesel systems the injector has to seat into the seal perfectly, otherwise, a pressure bypass can occur, which will reduce the compression in that cylinder and provide very reduced performance, even when a new injector has been installed. (This will often produce degraded combustion).
Here at Darwen Diesels we stock a wide range of Washers for seating & sealing. We have, on our database (which is meticulously maintained and updated) over 100 individual parts covering both European and Japanese engine types.
We pride ourselves on having a comprehensive range of Common Rail copper & steel injector seating washers for Bosch, Delphi, Denso and Continental VDO applications.
If there is a washer or seal you need that you don’t see in our range, please do not hesitate to contact us and we will always do our best to locate that individual part for you.
We stock all of the most commonly used Injector seating washers found in cars, light commercial, commercial & agricultural, Marine & Plant equipment. Our sales and technical staff are highly experienced in the field of seals and washers and will be only too happy to advise you.
We stock not only the most commonly used seals and washers but those hard to find specialized items such as; injector washers, flame trap & heat shields, leak off washers, pump washers, filter and banjo washers.
All of our copper seating washers are annealed during the manufacturing process, making them soft and malleable in order to create a secure seal when the injector is fitted.
