Use the following method if you cannot find the

correct pipe size or wall sleeve from the Sizing Charts

on pages 4 through 7.

Step 1 Calculate the Annular Space

The Annular Space is the space between the Outside

Diameter of the pipe and the Inside Diameter of the

Wall Sleeve or opening. This is calculated by using

the following formula:

Annular Space =

Wall Opening I.D. - Pipe O.D.

Step 2 Selecting the PEN-SEAL Model

Select the proper PEN-SEAL model from the Dimen-

sional Chart (shown below) by comparing the Annu-

lar Space to the Neutral State and Expanded State

Thickness. The Annular Space calculated must fall

between the Neutral State Thickness and the Ex-

panded State Thickness.

Step 3 Calculate the Number of Links Required

First, calculate the Bolt Circle:

Bolt Circle =

Wall Opening I.D. + Pipe O.D.

2

Then, determine the number of links required by

using the following formula. Chord Length is found

in the PEN-SEAL Dimensional Chart shown below.

Number of Links =

Bolt Circle x 3.14 (

π

)

Chord Length

Finally, the number of links determined must be

rounded down to the next whole number.

Please Note: PEN-SEAL sets are sold in belts of ten (10) links.
