If your tub was manufactured after May of 2008, replacement jet parts can be purchased from www.whirlpooltubparts.net
IMPORTANT NOTE: In May of 2008, we changed our jet design. All jets and jet trim manufactured prior to this date were discontinued by the manufacturer. The following websites may have inventory of these older jet parts/trim:
www.uspartscenter.com
www.spasandmore.com
www.spaparts.com
www.spaguts.com
www.spacare.com
Part numbers for these jets and the jet trim are not available, so the photos on the website will need to be matched to your current jet parts on your tub to ensure the proper items are ordered.
