185 Expanded
PTFE Joint Sealant
pH 0 -14, inert to
all common chemicals
Handles pressure from full vacuum
up to 3000 psig ( 210 bar)
Temperature range from
– 450°F (–268°C) up to 600°F (315°C)
Meets FDA requirement
21 CFR 177.1550
Fast and easy to use
Superior sealability, even on worn
or uneven flange surfaces
Long lasting, high reliability seal
with minimum re -torque requirements
100% virgin PTFE with
micro-fibrillated internal structure
for excellent stability
Micro-fibrillated structure turns ordinary PTFE into a
dimensionally strong, creep resistant gasketing material.
CHESTERTON Expanded PTFE Joint Sealants are soft
and pliable to conform to worn or uneven surfaces
and effect a tight seal. Yet they are resistant to cold flow
and creep for long, reliable life. Lay out even complex
shapes quickly with 185 on a spool. No waste, no fuss.
Mechanic friendly box of four popular sizes eliminates
trips back to the store room
for the right size gasketing.
Self-adhesive strip
holds 185 in place
for easy assembly.
For large areas
and cut gasketing,
we offer CHESTERTON
184 Expanded
PTFE Sheet.
