Subcategories

  • Common Rail Injector Washers

    With an ever-expanding market for choice of vehicles, we increase our range of washers frequently, making sure our stock covers virtually all makes.

    It is most important that the injector has the correct thickness of seating washer so that the atomised fuel is ignited and burnt at the correct point in the compression chamber. Failure to do this could result in lack of power, unburnt fuel and in some cases excessive smoke.

    The majority of our seating washers are copper or phosphor bronze, and occasionally steel.

    Contact us for more information about the correct seating washers for your specific application.
  • Common Rail Pump

    We carry stocks of sealing and high pressure washers for most Common Rail applications.

    There are not many washers in a common rail pump, and of those that we supply, the vast majority are in a repair kits. Please advise us of the pump number and we can supply you with the appropriate repair kit.

  • General Injector

    As a supplier to the Diesel injection aftermarket for over 45 years, we pride ourselves having a very wide range of washers varying in size and thickness to cover the majority of applications.

    As with the common rail injector, it is most important that the injector has the correct thickness of seating washer so that the atomised fuel is ignited and burnt at the correct point in the compression chamber. Again, failure to do this could result in lack of power, unburnt fuel and in some cases excessive smoke.

    The majority of our seating washers are copper or phosphor bronze, and occasionally steel.

    Contact us for more information about the correct seating washers for your specific application.

  • General Pump

    Our extensive stocks of washers for pumps range from steel tab washers and shake proof washers to copper, phosphor bronze, and nylon delivery valve washers. Many more washers are used in old-style pumps than the modern common rail type, a lot of which we stock individually or as part of a full repair kit.

  • Miscellaneous

    This section covers a range of washers which can be used for general purpose, check relevant sizes.

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.

We also stock Washer wall charts, which are always available on request.
