1 Review of Dusky Power Pump - Clear -

I bought this partly to try the PE experience-it's a great feeling as you watch yourself fill the tube. The pump and the comfortable silicon seal work well. However the cylinder itself is made of a too-soft plastic, it collapses in at about 5in/Hg vacuum.(30in/Hg is max vacuum, 20 should be achievable) The main reason I bought it was to use the cylinder for casting myself, which it will do well enough
