start by choosing a gasket shape
To achieve the results you want and to gain the most out of using our Gaskets Direct website, please see our guidelines below. If you have any questions relating to your order or if you would like to speak to an expert please call our manufacturing facility and head offices on 01425 278011 or email email@example.com
Our online gasket ordering system has built in limitations to avoid incorrect specifications being submitted. In addition we are able to provide a more competitive quotation where order volume is high. In this instance we ask you complete and submit your order for evaluation.
Whilst our online system does not accommodate some gasket designs, we do have a range of techniques at our disposal at our in house production facility, enabling us to manufacture almost any gasket possible. In this eventuality please contact us with your requirements and we will supply you with a quotation.

Our online ordering system has been developed for our CNC Digital Cutting Machine. Due to the mechanical techniques used to cut the smallest and largest of gaskets, we have factored in order thresholds based on material thickness and your specifications. These thresholds take into account the following rules where applicable.
ID - INSIDE DIAMETER
Your inside diameter of your gasket may be no smaller than your chosen gasket material thickness. This threshold avoids material tears or imperfections upon production.
Example: If you have chosen Viton rubber at 3.00mm thick, the minimum ID you may have is 3mm.
See diagram  - Measurement [A] must be equal to or greater than measurement [B]
OD - OUTSIDE DIAMETER
Your Outside Diameter is limited to 1000mm on this online ordering system.
We can produce much larger gaskets to your specifications using a range of production techniques, please select "Custom/Specialist Gasket" from step 1 and fill out the form submitting any accompanying notes and images.
We will respond to your gasket quotation request within one hour Monday to Friday, 9.00am to 5.00pm.See diagram  - Measurement [A] Outside Diameter
Your gasket flange width must not be smaller than your gasket material thickness (see diagram). Flange size is the difference between your OD (Oustide Diameter) and ID (Inside Diameter) at its smallest point.
Example: If you have chosen Viton rubber at 5.00mm thick and have an ID of 5.00mm, your OD must be at least 15.00mm (material thickness plus ID).
See diagram  - Measurement [A] must not be smaller than Measurement [B]
PCD (PITCH CIRCLE DIAMETER)
The PCD must not exceed the OD (Outside Diameter) or be smaller than your ID (Inside Diameter) of your gasket AND leave enough rubber either side of your PCD hole to a thickness of or greater than your material thickness selection (see diagram).
To ensure cutting your gasket is viable, ensure your flange size (Outside Diameter minus Inside Diameter) is equal to a minimum of your PCD hole size diameter plus 2x your material thickness choice.
Example: If you have chosen Viton rubber at 6.00mm thick, PCD holes at 4.00 diameter and have an ID of 6.00mm, your PCD should be marked at 22mm and your OD should be 38mm (minimum feasable production threshold), giving a flange width of 16mm.
See diagram  - Measurement [A] must allow space for your material thickness [C] either side of your PCD hole diameter once your PCD has been taken into account.
ORDERS OVER £500.00
To ensure we give you the most competitive quotation we have limited our quote/online ordering system to £500.00. Typically we can reduce production costings and therefore our customer quotations above this value. If your quote/order value exceeds this, please submit for evaluation and a dedicated member of the team will respond to your enquiry as soon as possible.
