This listing is for (1) NEW rear rubber flange with brass insert, as used on the Victor Exhibition reproducers.

The isolator is assembled using an original Victor brass insert bonded between two pieces of 70 durometer

neoprene die cut rubber.

They are engineered to have the correct spacing (gap) between the insert and the rear of the reproducer body.

Easy to install and make a huge improvement in the sound quality of your reproducer.

I would suggest using a tiny amount of sealant between the flange and the back of the reproducer rear housing

to insure an airtight seal.
