WTB: Thermo rebuild kits

[pdoege]

I need rebuild kits for 2 thermo valves. Preferably with the new fangled crush fittings, but I'll take the o-ring type as well.

Thanks,

Fill Express in Pompano Beach has them.

Tell me what you need (specifically, if you know) - I've got a fairly good assortment of the Thermo parts. The only "special" stuff in there is the seat plug, the crush washer, and the teflon ring that goes in the bonnet nut.

Only the crush washer is a "must replace" when disturbed, plus, of course, the O-ring on the stem. Attempting to re-use the crush washer almost always leads to leaks and, if you crank it down enough to stop them, you can strip the bonnet which of course destroys the valve.

On the Diveriteexpress site #s #16 and 17 are "must replaces", and #5 is often dinged enough to require replacement. Unless the seat plug is damaged or the valve is leaking (when turned off) there's no reason to replace it.

Those copper crush washers are NOT expensive and the O-ring is readily replaced with an EPR or VITON generic.

$20 isn't a horrid price if you NEED the plug, as that's about half of it. However, if the seat is ok then its pure insanity to buy a $20 kit when the packing and crush washer are all of a couple of bucks.

I tried to half ass the crush fitting without replacing it. No damage done, but of course it leaks.

It was the first time that I had encountered crush fittings on a valve, so I didn't have any spares.

I ordered a "rebuild kit" from DR Express just to have one around.

Thanks for the heads up on the parts list.

Out of curiousity, why is #17 a must replace? I always clean, inspect and reuse unless they are damaged/deformed/etc.

Good engineering practice is that any dynamic O-ring is replaced when disturbed.

Given that they cost just a couple of pennies, its silly to re-use it.

Just buy them from www.air-oil.com - that way you're not tempted to re-use them because you paid a couple of bucks for a 5 cent O-ring.

Thanks Genesis.
