What Does a Good Seal Engineering Drawing Look Like
                     What Does a Good Seal Engineering Drawing Look Like? 
You simply went through a half year testing, extending, maturing and uncovering your new seal 
structure to 12 unique synthetic substances. At last, you are done, so what does a decent specialized 
drawing for a seal incorporate? For most organizations, the drawing is straightforward. For an O-ring, we 
draw a conventional circle and show an ID and width with some kind of material get out. However, 
presently quick forward 20 years, somebody counsels the drawing, how would they know the models 
you used to choose the seal determined?  
Simply a week ago I asked my client who was having seal disappointment issues on their motor sensor, 
"Was the first seal indicated to be viable with biodiesel?" The designer counseled their drawing, yet 
alongside the nonexclusive circle it came up short on any foundation on what material similarity was 
viewed as when the seal material was chosen. The ASTM depiction on the drawing did exclude a 
reference to or demonstrate similarity with biodiesel. 
Be specific with materials 
After some time, the working boundaries of a framework or item can change so it is imperative to 
comprehend what boundaries were utilized for the first seal determination. The objective of the 
attracting is to guarantee that the architects and acquirement group comprehend what execution is 
required from the Sealing drawing and why the particular elastomer was picked.  
So how would you make your attracting more important to your organization?  
Characterize and rundown on your drawing all the working conditions you envision the seal will consider 
such to be temperature, pressure and some other application explicit working conditions.  
Set up a rundown of liquids just as the groupings of 
every liquid that your seal will be presented to and again 
include these your drawing. Moreover, ensure you 
consider liquids that could come into contact with the 
seal by implication, through disappointment of different 
frameworks that are important for the item or even by 
cleaning the item.  
Rundown on the drawing the chose compound and 
producer. Characterize obviously what testing the 
compound was gotten through or what testing is required for endorsement.  
In the event that you select an intensify that was impervious to pressure set, high temperatures or low 
temperatures just as dangerous decompression, this ought to be obviously expressed on the drawing.  
Rundown obviously the business norms the seal is needed to meet, for example, UL, FDA or NSF. 
List fluid compatibility requirements 
Over and over, I see seal quality and execution disappointments when another provider is chosen and 
the genuine prerequisites for the seal were either overlooked or not unmistakably characterized. Plainly 
characterizing these boundaries and making them straightforward will permit your buying and 
specialized group to comprehend, choose and assess the right intensify that meets your items fixing 
prerequisites.

compound picked is viable with the liquids you are utilizing. Parker can regularly gracefully little 
compound examples for absorb testing the liquids your seal is presented to. On the off chance that you 
decide to list a substitute compound on your drawing, that compound should likewise be tried and 
approved for similarity.
