It is leaking air at the regulator and both Amazon and Ebay do not list the regulator by itself but do sell the regulator WITH the manifold for $200 +- This regulator started leaking last year and the only part available then was a "REPAIR KIT" which I installed,,but now that DANG thing is leaking again. You can order a manifold from amazon or ebay with the regulator but no gauges etc but also very pricey,,,,,

dont see the reg by itself.... you can get the ENTIRE package with gauges and reg for $200 as you said... this appears to be the CHEAP option.... unless you buy a generic regulator and some pipe fittings and screw everything together... Probably still have $90. in that.. ------------- Like them all, but love the "B"s. |

Hey Steve,,I was hoping to buy an OEM, shore enough Dewalt regulator as I already bought one of these "generic" rebuild kits for that regulator a year or so ago. The Factory (OEM) Dewalt regulator was NOT available then either,,,,? The main item description heading on this one says OEM,,,then right below that,,it says Brand is GENERIC,,,,?? The "Complete"one you also refer to at $200 is also "generic" Being some what,,,"Thrifty",, I am now considering looking for a popular brand name regulator with it's base fitting and make my own manifold as there seems to be lots of traffic for the Dewalt replacements,,,prolly for good reason,,,errrr,,,bad performance,,,!!

I went to HF and purchased an inline regulator for my roll around unit (Campbell Hausfield). I reused the gauges and other fittings and didn’t have to spend much money. ------------- Just an old country boy saved by the grace of God. |

Hey Hubert,,Thanks for the comeback,,,,Yes,,that right there is what I figured to do to get a quality regulator. I'm now thinking the Dewalt regulator is manufactored for that specific manifold and the china rebuild kits that are being offered are some less than optimum clearances as the leaking has been thru the regulator adjuster body itself as the adjustment changes is to "PULL" the knob to adjust,,then push down to set,,,kinda a rube goldburg sort of fu,,,! I saw the one by Porter Cable ($16) that HF offers and it is a name brand product and I expect I will rebuild the whole manifold to my specs and reuse only the 2 gauges and the pressure relief valve and replace the 2 hose quick connects as they are also less than optimum. Thanks again.

If that part pictured is a manifold - then I would make up my own from pipe fittings . Standard Sch 40 water pipe is rated at 125 PSI so if you set pressure switch to that or less it would be OK or go to next step and get Sch 80 pipe and fittings with a 220 PSI or greater . I would make a manifold with a couple ports and install quick disconnect fitting into it so regulator could be plugged into it when needed , not in use at all times . ------------- Life lesson: If you’re being chased by a lion, you’re on a horse, to the left of you is a giraffe and on the right is a unicorn, what do you do?

YEA,,!!!,I've always been of the opinion that great minds think the same way to resolve a puzzler, thanks to these folks that take the time to help others, My plans are to use 3/8" S/40 CS pipe fittings to make up my manifold with two new quick connects as the factory ones are so Dang hard to force the hose end into the quick connector. Plan to also reuse the two pressure gauges and the relief valve as no issues there either,, Wish me luck,,,and Thanks again,,Guys |

schedule 40 steel pipe in 3/8 or 1/2 inch is a few THOUSAND pounds of pressue.. No problem using it in an air compressor running under 200 psi. ------------- Like them all, but love the "B"s. |

Have you tried ereplacementparts.com? My accountant says to try toolservicenet.com. She works tool warranty/repair at Acme Tools I just looked at the second listing. Manifold assembly $150 |

OK,,I corrected my misprint as the 80 fittings are not available so s/40 it is. I was able to find all the fittings for the manifold to do away with the dewalt bs, and this way if the different design regulator does go belly up,,a replacement will be able to be replaced with something readly available,,,and thas all I got to say bout that,,,,

Sch 40 pipe itself might have a higher pressure rating but threaded joints will diminish that as will the fittings used to connect pipe to threads . In 1/4 - 3/8 pipe fittings may be the point where pressure rating comes into problem ------------- Life lesson: If you’re being chased by a lion, you’re on a horse, to the left of you is a giraffe and on the right is a unicorn, what do you do?

For schedule 40 galvanized fittings, the general cold working pressure (WOG) rating is 300 PSI. This rating is consistent for both 1/4" and 3/8" sizes. < jsuid="veYr3c_3" ="0" -amic="true" -icl-uuid="064eacd0-b7ca-4f44-8330-8b75fa63990f" aria-label="View related s" ="rBl3me" js="click:S9kKve;mouseenter:sbHm2b" -ved="2ahUKEwiE5I7w2--PAxUH1fACHaIYDJIQye0OegQIARAB" style="margin: 0px 6px 0px 0px; : none 0% 0% / auto repeat scroll padding- border- rgb229, 237, 255; border-width: initial; border-style: none; border-color: initial; border-radius: 10px; height: 20px; padding: 0px; width: 28px; : relative; outline: 0px; cursor: pointer;"> http://www.w3.org/2000/svg" rel="nofollow - http://www.w3.org/2000/svg" viewBox="0 0 24 24"> Key pressure ratings for galvanized fittings

Well, Gents,,,,I finally got all the fittings rounded up to fashion a new manifold for the air compressor and was surprised at the laack of small sized threaded fittings in this little ole burg,,,,fact IS I could not find enough 3/8" fittings ,,so I had to go with 1/4" fittings with 3/8" X 1/4" bushings coming out of the new regulator,,,,Sheeesh,,,!!! The portable compressor is happy now,,,I'M Happy and no air leaks,,!! Many Thanks for all the help and suggestions. In retrospect,,,I shoulda just used a simple regulator like is on the main compressor with the "T" handle adjuster,,,,as ole Jay tends to lamment,,,,,Sigh,,,Sigh,,,,
