Gasket Kit / Installation 

Only aluminum and cast iron pumps come standard with expanded PTFE 
Gasket  Kits  (P/N  15-9500-99).  Carefully  prepare  sealing  surfaces  by 
removing all debris and foreign matter from diaphragm bead  

and  all  mating  surfaces.  If  necessary,  smooth  or  deburr  all  sealing 
surfaces. Mating surfaces must be properly aligned in order to ensure 
positive sealing characteristics.

  

 

 
 

 
 

 

 
 

 

Step 1

 

Gently remove the adhesive covering from 
the back of the PTFE tape. Ensure that the 

adhesive strip remains attached to the 
PTFE tape. 

Step 2

 

Starting at any point, place the PTFE tape 
in the center of the diaphragm bead groove 

on the liquid chamber and press lightly on 
the tape to ensure that the adhe- sive holds 
it in place during assembly. Do not stretch 

the tape during placement in center of 
diaphragm bead groove. 

Step 3 
The ends of the tape should overlap 
approximately 13 mm (1/2"). Proceed to 
install the PTFE tape on the remaining 

liquid chamber.
