ELASTOMERS & REPAIR KITS

WETTED ELASTOMERS

II 2 GD c TX

Warning: The TX marking refers to the maximum surface temperature depending not on the equipment itself, but mainly 

on operating conditions.  In this case, the maximum surface temperature depends upon the temperature of the process 

fluids. 

FKM 

is an elastomer with good corrosion resistance to a 

wide variety of chemicals. Temperature range  -40°F 

to 350°F (-40°C to 177°C).

Most of the above elastomers are available in FDA 

approved formulations.

BUNA-N (NITRILE)

is a general purpose elastomer used with water and 

many oils. Temperature range 10°F to 180°F (-12°C 

to 82°C).

GEOLAST® 

is an injection molded thermoplastic material with 

characteristics similar to Nitrile. Has excellent  

abrasion resistance. Temperature range 10°F to 180°F 

(-12°C to 82°C).

EPDM 

is a general purpose elastomer with good resistance 

to many acids and bases. Temperature range  -40°F 

to 280°F (-40°C to 138°C).

SANTOPRENE® 

is an injection molded material with characteristics 

similar to EPDM. Has excellent abrasion resistance. 

Temperature range -40°F to 225°F (-40°C to 107°C).

PTFE (POLYTETRAFLUOROETHYLENE)

is a thermoplastic polymer that is inert to most 

chemicals. Temperature range 40°F to 220°F (4°C to 

104°C).
