$2.00 part that really works - snubber

[damon]

For 6 months now I had been listening to the boost guage rattle as pressure dropped, and it seems like a common issue across all but the digital gauges. I have read over and over that a snubber will fix it, so I finally ordered one from BD, and must say that it works as advertised. Now the guage is silent, and responds just a hair slower than without the snubber, but very acceptable.



Thanks for the advice - again

Is the snubber 1/8" or 1/4"??

the snubber that I got is 1/4" MIP thread, which goes into the 3/4" - 1/4" IP adapter on the intake manifold, and then has an 1/8" compression fitting for the boost line. It is exactly the configuration I needed, and if you want I can find the part # so you can pass it on to the nice folks at BD when you order. One thing worth mentioning though, it cost $10 to ship that $2 part from Canada, but it was worth it !

Thanks Damon. I don't know of an 1/8" snubber available. You can get 1/4" snubbers at Graingers' (part #5WL13) for a few dollars each. I was hoping (thinking) it might have been an 1/8".

I've never seen an 1/8" snubber but that doesn't mean they don't exist. In most applications the snubber is connected right to the gauge, most gauges are 1/4" NPT.

An easily available 1/8" needle valve shut most of the way down will work just as well and cost about the same as a snubber.

Just a thought here, what would happen if I tightened the compression fitting down real tight, problably wouldn't help or work is the reason I haven't done it yet but what do you guys think.

I use Bill's needle valve "snubber" on all of my pressure lines. It works EXTREMELY well. Total control and if there is a little leak, just turn the needle valve all the way off. One of the BEST ideas I have found on the forum threads, inexpensive too.

Bill- I've discovered the same thing. We deal with alot of small gauges for process control in my line of work and NONE of them have anything available. I never thought of using a needle valve- but it would make a good snubber. I use lab quality needle valves made of CPVC to create flow diversion in our lab all the time.

Ron, if you reef down on the compression fitting one of two things will happen, either the ferrule will distort so bad that it leaks or the compression nut will crack so that it leaks. Many folks overtighten compression fittings and make them leak, finger tight plus half turn with a wrench is plenty



Kev, Grainger has 1/8'' needle valves in any configuration you can dream of - angle or straight, femaleXmale, MxM, FxF, M or F x compression, compression x compression, all are under $5 unless you get fancy with stainless.
