Gasket Kit / Installation 

 

P1  PVDF  and  Ultrapure  pumps  come  standard  with  expanded  PTFE 
Gasket  Kits  (P/N  01-9501-99)  for  all  sealing  surfaces.  P1  Poly  pumps 
come standard with expanded PTFE Gasket Kits (P/N 01-9500-99) for 

diaphragm bead only.  

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 and is not removed with the 

adhesive covering. 

Step 2

 

Starting at any point, place the PTFE tape 

directly on top of the diaphragm bead. Press 
lightly on the tape to ensure that the adhesive 
holds it in place during assembly. Do not 

stretch the tape during placement on the 
diaphragm bead. 

Step 3

 

The end of the tape should overlap 
approximately 13 mm (1/2"). Proceed to 

install the PTFE tape on the remaining 
diaphragm.
