new bowl seal kit for the HCM 450/300. Made from strong, food grade plastic. Includes food grade lubricant for installation.
There are a few different style seals for the HCM 300/450. To determine if this bowl seal will fit your HCM, measure the thickness of your OEM bowl seal (see image). The plastic body of this bowl seal measures just under 1/2" of an inch thick (.450").
