Encapsulated Cartridges
The SAE Encapsulated cartridge allows the user to eliminate the
space and labor required to install and assemble a conventional pipe
thread fitting connection. The cartridge is retained in the cavity by 3
barbs versus the normal 2 barbs for better performance over a wider
diameter tolerance range.

Cavity Specifications
Dimensions are per the proposed SAE Standard J2494-4. The SAE Encapsulated Cartridge
is thoroughly tested to meet or exceed the performance requirements of D.O.T. FMVSS
571.106
and SAE J2231 and the proposed dimensional standards of SAE J2494-4 in 6061-T6
aluminum. Cavity dimensions specified by SAE J2494-4 need tp be adjusted slightly for optimum
performance in material other than 6061-T6.
Installation
Apply force evenly over the top surface of the cartridge body until the cartridge shoulder bottoms
out on the top of the cavity. The amount of force required will vary depending on the cartridge
size and the material of the cavity.
