Review on Speedfit PPSV500822WP 4 Inch Female Valve by Steve Hardy

The quality of this valve is much higher than that of PureSec (https://www.amazon.com/gp/product/B01N1RL2WK/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1) which is also here on Revain is offered. First, it has a structural metal support ring built into the base around the threads to prevent cracking when tightened. The valve itself feels more solid and the locking actually works, whereas on PureSec the locking tab can't stop the grip with too much torque. There is simply no comparison between the two valves. Only $1.00 more expensive than PureSec, at least three times the price.
