I trust PLC, they are industrial parts supplier more than a liquidator, and they don't offer too much discount if the parts are currently circulated model.
And they list the part according to manufacture MSRP/retail price, and tech spec.
Okay, this is the last I'll say about the HR3 price.
This is a fantastic deal. This valve outperforms the vast majority of everything we've ever commonly used in this hobby.
But I have no qualms about questioning seemingly inaccurate claims. A savings of (not quite) four hundred
dollars by replacing a tiny seal and changing the thread gender and size - according to the liquidator's estimated retail price - is ludicrous. And then another $128
for a cheaper handle. So, no, I don't trust the liquidator's estimated retail prices. At least, not this one.
4M-H3L-KZ-SS-TC (1/4" Male, H3 valve, Kalrez seal, SS, turn counter knob)
2F-H3L-V-SS-TC (the Evilbay model, with 1/8" Female, H3, regular flourocarbon seal, SS, turn counter knob)
And then, if you replace the turn counter knob with a regular knurled knob, you get:
Okay, I'm done. Get this valve while you can! But you're not allowed to tell yourself you saved eight hundred dollars off the retail. Four hundred at most :P
