A gasket is a shaped mechanical seal which fills the space between two or more irregular mating surfaces. Usually used to prevent leakage from or into the joined objects while under compression. Commonly produced by cutting from sheet materials.

Funny how nobody cares about a gasket until it leaks or breaks!

Suddenly, Everything is put on hold while you look for a replacement.


At Paramount, We've been cutting our own gaskets for over 30 years. We even started by hand-cutting gaskets! Eventually, we bought some expensive die-cutters and presses. That worked for quite a while. But making different sized dies was expensive, and it was difficult to switch production runs. We had to charge the customer for the full sheet because we couldn't use the scrap for anything else.

These days, we use state-of-the-art blade cutting machines, and it has made all the difference! We can take any 2D autocad drawing, and the machine will calculate what is the best way to cut the pattern on the sheet material. Even our scrap is reusable! That means our production yields per sheet have gone way up, and our production costs are way down. Our production schedules are more flexible becase we can switch from job to job, or squeeze in several small jobs on one cut. This significantly improves our production work flow and we are able to get more jobs finished and on time. With a warehoue full of prime gasket materials, we can cut tens of thousands of gaskets a month without experiencing backorder issues.

That's why Paramount is the Best Place to get your GASKETS!

A full-face gasket is going to have some bolt holes. So you need to know the outer diameter (radius * 2), the inner diameter, and the bolt hole center diameter. You also need to know the bolt hole count. if all the bolt holes are equal distance, then this can be calculated. if not, then you have to measure the angle and distance of each bolt hole center from the gasket center. See the chart for ANSI standard gasket sizes

A little trickier to work out. First, you have make sure you have the dimensions of the first bolt hole in the upper left hand corner. Then, moving clock-wise, make sure that the distances between bolt hold centers are equal. if not, then you have to measure each distance to get an accurate reading.
