Hygienic Sanitary Gaskets
Compression Controlled Gaskets
for Aseptic Markets
Superior Performance
for High Purity
Processing
Parker’s hygienic sanitary gaskets are
patent pending designs which offer
long-term sealability, excellent wear
performance, complete material
traceability and easy installation.
Our sanitary gaskets are designed
to meet typical ASME-BPE hygienic
clamp unions with a nearly flush
interface (± .008"), preventing the
entrapment of any media within
a dead space that can lead to
microbial growth and contamination.
In addition, the flush interface helps
prevent erosion of the elastomeric
gasket that could contaminate the
process stream.

Over-Molded Rubber to Plastic Design
Parker’s hygienic sanitary gasket type B design provides superior sealability,
alignment and traceability.
Reduced outer bead size prevents
over-fill condition that would cause
seal bead to extrude into tube
Outer clip
aligns gasket
with ferrule
Inner seal beads provide
primary point of sealing
(increased sealing pressure
over existing designs)
Extended plastic
support stabilizes the
seal beads and limits
extrusion into the tube

Laboratory Testing
for Intrusion & Sealability
Test Results
During product development, Parker’s sanitary gaskets
were evaluated side-by-side with various industry leading
sanitary gasket suppliers' products, by an independent test
laboratory. In doing so, Parker confirmed its products
perform better than what exists in the market today.
A
After the completion of 500 steam-in-place cycles,
Parker’s gaskets exhibited an average of .003" of intrusion.
Compared to the competitor’s gaskets, Parker’s ethylene
propylene (EPDM) gaskets displayed:
r A minimum of 90% less intrusion
r The ability to hold pressure without having to
re-torque the clamp, resulting in labor cost savings.
r The ability to disassemble the joint and remove the
gasket by hand without the use of external tools,
improving the safe removal of the gasket and reducing
labor costs.

Material Traceability
Each sanitary gasket has a laser etched product
identification on the part to allow for full traceability.
The etched identification includes codes for the
material type, manufacturing date, shift, and month of
production. Parker’s internal rubber mixing capability
ensures full traceability back to the raw ingredients
used in production.
