Notice: Cleanliness during installation is crucial to the satisfactory

operation of the MSS seal.

Caution: Installation of this seal requires the use of an adhesive to bond

the O-ring secondary seals together. Do not allow the

adhesive to come in contact with skin.

There are two basic models of the MSS seal, Piloted, see Figure 2,

page 4, and Non-Piloted, see Figure 3, page 8.
