Snubber differences

[015point9]

Are both these things snubbers?  The "sinster" one holds back pressure more, giving it a blow test.  But if any breaks off would not want particles going thru system or are they better?

any chance of just putting the restrictor in with a ball valve to have further control

[GSP7]

Which on is the "sinster" ???

 

Mine is like the smaller one.

 

My guess is neither work

OP here...

"Sinster"one is on right side in both pic's.   And also going to use needle valves for flow control and shut off valve.

Is sinister the real name of these?  I Google sinister and get countertops .

they are switched right and left

Sinister...is real thing.  I thought slang or joke.  Mott Corp makes something like it.

It is sintered metal, not stone. Sintering is the process by which it is made. The vent on my EB is made from it. Google sintered metal.

Yes...

Today's vocabulary word for me?

Not sure...ball valves that small with couple reducers?  The hydraulic store I use doesn't ball valves that small only needle valves in 1/4 inch size.  Not saying some other place does though.

Better view for people.

 

[dripley]

That's good view. Lots of tiny particles smashed together.

[015point9]

So in pic's at beginning of post...these are both snubbers?  

 

And no problem with sinister material coming loose in a fuel line?  

( I suspect not being Vulcan sells them, just a gut feeling)

I guess there’s always that off chance but I’d doubt it. Worse case scenario is some does break off and could clog your gauge or ruin it.

[dripley]

I am sticking with the needle valve just because it works, not because of any fear of the sintered metal. It has been around for a long time. 

[Haggar]

Those both seem to be "snubbers".  But for our application the orifice is too large.   The one I use has a 0.004" orifice in it.   The sintered metal is a filter to prevent a particle from reaching and blocking the orifice.

A lot of places dump all the snubbers in one section and never mention orifice size.  McMaster-Carr lists them by orifice size.

 Does it work ?  with a fass pump, 1/2" fuel line, Tee about a foot from the vp44 ?

 

The snubber I got from vulcan didnt do anything. I had a extreme gauge bounce

[Haggar]

Hmmm,

 

I use a tapped banjo bolt at the vp inlet.  I have 18" grease gun hose with snubber, coupling, and pressure transducer.  I have a nice steady gauge. (too low of a pressure....but that is the lp's fault....).   I also bleed that line during assembly.  Trapped air can cause weird fluctuations.... It acts like a spring in the system.

 

If you have the old snubber around, see what diameter hole is in it.  He may have just gotten a batch with big holes in them.

 The snubber I got from Vulcan is .165 hole...

 

So these sinster metal ones are not even a snubber, its more of a small filter

 

It looks like the large whole sinster metal one in the picture above

 

I have a needle valve snubber now. Every thing is workig good now
