Replacement part for a Termovar loading unit?

WireNut · Nov 12, 2013

I have a cracked nut on one of the valves on my termovar loading unit. Part number 19 on page 6 of this pdf:

http://www.acaso.se/Global/LK_Acaso/Monterings_bruksanvisningar/TERMOVAR_LU_EN_200612.pdf

It's the 1 1/2 x 1 1/4 " model. Does anyone know where i can get a replacement for this part? It doesn't have to be this valve, but a part that will fit here would be just fine, I have a ball valve after the unit, I just need something that will fit here.

Just the nut and washer would be fine, but I have a feeling I will need the whole thing. If there is no part readily available, what can I do to replace the part? Will a regular 1 1/2" copper fitting work there?

I would think the threads on body of the loading unit are straight threads as the nut just tightens the rubber seal against the body. So I don't think an 1 1/2" female NPT would fit well with 1 1/2" straight threads but I don't know.

As far as replacing the part or parts you might try Dean at http://www.smokelessheat.com/ or the folks at http://www.woodboilers.com/ as they both deal with the LK Acaso products.

How about gas fittings.

Gas fittings? Could you point me toward some?

Your local hardware store or plumbing supply.

That is a special nut designed to slip over the lip of the tailpiece. Good chance the threads are BSP metric also. Best to go back to the supplier.

Any chance that could be brazed? If you can't find a replacement quickly? Doesn't necessarily have to be pretty, and doesn't necessarily have to be a water tight weld as it just functions as a nut to tighten the flange against a rubber washer.

I replaced mine with just black iron. I used too big of a wrench to tighten. Took off the little shutoffs and put in black iron unions. Good as new.

Did you use 1.5" black iron unions? Similar to this: http://www.pexsupply.com/Ward-FBUN1-1-2-1-1-2-Black-Union-735000-p

I had a local guy do it. And yes i think it was 1.5. Contact Tarm, they should direct you.

Thanks. The 1 1/2" black iron union worked perfectly. I changed the 1 1/4" copper x male to a 1 1/4" copper x 1 1/2" male, put it all together, and it's holding tight!

The original parts of the termovar are a bit sensitive to me and a 3ft pipe wrench. Glad it worked.

Yeah, me and a 2 foot pipe wrench had the same problem, as you saw.

I'm so used to how hard it was to rip out the old iron pipe my heating system was made of (6 foot bar on the pipe wrench for leverage) that sometimes I forget how fragile brass and copper are.
