GE Quick connector with cams

The seal is ensured by flat gasket of soft elastomer like Silicone or Neoprene.

I preferred a flat seal rather than an O-ring because the latter needs a groove with stable dimensions. In fact, the sealing O-ring depends on the slight compression exerted by the groove in order of a few tenths of mm.
Indeed the piece called "Cavity" constructed of a material by injection molding as ABS, under the action of pressure of 3 Bar deforms greatly moving almost 1 mm thus affecting the sealing of the O-Ring.
If eligible would be better to add ribs at the bottom to give more stability
I also increased slightly the contact surface for better sealing.

The success of the sealing of the gasket depends also on the application of a correct load that ensures the right compression set.

The tightening of the gasket is made from a series of out center cams.
The rotation of the cams ensures the insertion and reatining in position or with reverse rotation the expulsion of the cam to release the brick.
The cams are in stainless steel AISI 304 or 316, and can be added a security link to not lose them when disassembled.

To optimize the final version is necessary to establish the gasket compression set in accordance with the supplier.
To do this, raise or lower the center of the cam toward the seal so that rotation of the cam crush sufficiently the gasket.
