Common Rail Injector Washers
We cater for the ever- expanding range of vehicles on the market by continually increasing the range of common rail injector washers that we offer. This ensures that we cover as many makes and model of vehicle as possible.
It is crucial for the seating washer for the injectors is exactly the right thickness. This ensures that the atomised fuel combusts at the correct point in the compression camber. A reduction in power, the potential of excessive smoke and unburnt fuel could be the consequences if these measures are not adhered to.
While some of our injector washers are steel, the vast majority are copper or phosphor bronze.
If you need more information, or are not sure which are the correct seating washers for your engine, we have an excellent technical service which is available free of charge at the end of a phone or email. Please call us on 01254 53545, or fill in a simple contact form. We look forward to hearing from you!

General Injector Washers
As well as stocking and supplying a comprehensive range of common rail injector (or seating) washers for the ever-expanding market, we also offer a significant stock of seating washers for engines other than common rail. Really importantly, however, is the fact that that we back these stock levels with a level of technical knowledge that is second to none. Our staff, collectively, have many years of experience in the industry and are more than happy to help our customers with information that will help you with your choice of the correct injector washers for your particular application.
Getting the correct size and thickness of seating washer is vital because the atomised fuel needs to combust at exactly the right point in the compression chamber. If the thickness of the seating washer is incorrect, this could have negative consequences including unburnt fuel, the potential loss of engine power, and excessive smoke. If you have any doubts about the correct washers for your particular application, please do not hesitate to contact us, as our advice is entirely free of charge.

Miscellaneous
This section covers a range of washers which can be used for general purpose, check relevant sizes.
Seating and sealing washers play a vital role in the correct functioning of high-pressure systems. For example, every new injector kit is supplied with a soft annealed copper washer; that washer, though seemingly simple, acts as a high-pressure seal. If the wrong thickness washer is fitted, the atomised fuel from the injector would be directed to the wrong part of the piston crown and could cause incorrect burn of the fuel vapour and would not create the best burn for the power stroke of the engine.
The injector, in a high-pressure diesel system, has to seat into the seal absolutely perfectly, or else there is a risk that a pressure by-pass may happen, so reducing the compression in that cylinder which will result in a loss of power from that cylinder even when a new injector has been fitted. We supply a tool to remove the old seating washer if it does not come away with the injector and is still fixed in the cylinder head, also we do a reaming tool to cut any old carbon residue from the seat in the cylinder head for the injector but it must not be used to cut any alluminium from the injector seat, this would create a problem as previously explained.
We stock a number of the most commonly needed washers for seating and sealing, and we are second to none in our stock of Injector seating washers found in cars, commercial vehicles, agricultural vehicles, and marine and plant equipment. We have common rail copper and steel injector seating washers for Bosch, Delphi, Denso and Continental VDO applications. On our well maintained and regularly updated database, we have over 100 individual parts which cover both European and Japanese engine types.
As well as stocking commonly used seals and washers, we also have the harder-to-find more specialist items such as pump washers, flame traps and heat shields, banjo washers, filter washers and leak off washers.
To ensure that our copper seating washers are soft and pliable, and create a rock-solid seal when the injector is fitted, they are all annealed during the manufacturing process.
Our technical and sales staff are staff are highly knowledgeable and experienced in the field of seals and washers and will be only too happy to help if there is a washer or seal you need that you don't see in our range; we will always do our best to locate it for you.
