Good product! Fit my used 3 cfm JB platinum pump that someone else had butchered with the wrong fittings (big air leaks). They thought the pump would no longer pull down to 25 microns. It does if you stop the leaks.
The intake can be arranged to have 2x 3/8” inlets or 1/4” & a 3/8”. It is JB quality and was priced fairly.
