The Kalsi Seals Handbook includes rotary seal implementation and troubleshooting guidelines, with a special emphasis on oilfield seals and sealing applications.  It represents the collective wisdom of our senior staff members, who have many decades of experience in solving seal implementation challenges.  As such, it is an invaluable reference manual for existing customers, and for individuals who are interested in using our rotary seals.

The handbook is based on individually revisable chapters, which are hyperlinked below.  This format facilitates periodic updating, and avoids unmanageably large file sizes.  We recommend that you use the handbook directly from the website, so that you can always be sure of referencing the most up to date rotary sealing information. For a list of seal styles and sizes, see our shaft seal catalog.
