Prestomatic SAE Encapsulated Cartridges
Example: PMTCE -4
Prestomatic SAE Cartridge
1/4" (4/16) Tube Size
Advantages
Parker Prestomatic† SAE Encapsulated Cartridges are a compact,
economical design that allows the user to eliminate the space and
labor required to install and assemble a conventional pipe thread
ftting connection. Weight reduction and the elimination of pipe thread
leakage related to improper assembly techniques are achieved.
The SAE Cartridge design allows for faster and easier installation of
components and assemblies. The external o-ring seals radially and
does not require special chamfers at the top of the cavity to effect a
seal. The SAE Cartridge includes a built in tube support. Once the
SAE Cartridge is installed in a single step cavity, no special tools are
needed for tube assembly. Just bottom the tubing into the cartridge
body for a positive seal.
Materials
Parker’s Prestomatic SAE Encapsulated Cartridges have been
developed for both soft metal and plastic cavity applications. Consult
factory for specifc cavity or housing materials that would be suitable
for a particular application.
Specifcations
Cavity dimensions are per SAE Standard J2494-4. The Prestomatic
SAE Encapsulated Cartridge is thoroughly tested to meet or exceed
the performance requirements of DOT FMVSS 571.106. Cavity
dimensions specifed by SAE J2494-4 need to be adjusted slightly for
optimum performance in material other than 6061-T6.
