Eaton LJ11 and J11 Joints

LJ11 and J11 Joints were designed primarily to join standard tubing for fuel, hot air and gas systems. The substitution of couplings other than the coupling part numbers specified for each joint can seriously impair the effectiveness of the joint. Although these joints are basically the same configurations, the LJ11 flange skirts are lighter, and the gasket is thinner except at the sealing point. Therefore, the LJ11 Joint should be used when weight saving is an important factor. The J11 Joint is a heavier joint with a high safety factor.
