Note: New 23837 silicon carbide mechanical seal – Superior abrasion resistance and longer life. Standard in kits
shown above. 23837 is a direct upgrade of the 19878 mechanical seal (see “seal washer section” on page 2
to determine the proper spacer needed.)
The #1 reason for premature engine wear is overheating. To maintain engine
performance, insist upon genuine Sherwood impellers and service kits.
