manifold identification

naver2naver2 Posts: 2Member
Can anyone help me identify the manifold shown in the pictures attached? I can find no identification on it. it was installed in 2010 for radiant basement slab heating. There is a slight leak where one of the pex tubes (1/2 inch) enters, and I understand i need to know the manifold to get the right replacement fitting/adapter.

Any help would be greatly appreciated.

    what brand tubing is connected to it? Sometimes that is a clue. A name on the plastic caps?

    So many of those Euro manifolds out there, there must be hundreds of companies extruding them.

    Unfortunately, no markings anywhere, not even the plastic caps. The tubing had some faint lettering or numbering, but i couldnt make out any brand names.

    That tubing looks like a Viega heat pex version. Prob a SDR9 diameter tubing.

    looks like the leak is running down from the top, actuator tread? often you can disassemble them, dry off and use some pipe dope, to reseal a small leak.

    There are O-ring seals on the top and bottom connections, usually.

    Looks like Uponor.

    Hello, Three thoughts come to mind. First, is there a way to find out who installed it back in 2010? They would certainly know who made the manifold. Next, do the pressure gauges have any ID? If so, contacting them, showing them these photos and asking what manufacturer they supply with their gauges? Lastly, maybe the leak is fixable with some teflon or? I might just take it apart and have a look. ;)

    Yours, Larry

    Also the pex connection threads R-20 are fairly interchangeable between brands. The glitch would be if you have an odd metric diameter tube.

    Measure the OD, standard pex is the same OD as copper tube, called CTS. So 1/2" pex would be 5/8 OD, 3/4 pex 7/8" OD.

    I think it is a Chinese stainless steel manifold manufactured by Rifeng. http://www.rifeng.com

    You can always make a tight seal on threaded fittings on a manifold with 'Lock Tight' or 'Lock n Seal' if you have a problem seal.

    I buy my EPDM o-rings from http://www.oringsusa.com/

    On one job, I had odd sized pex and was using Caleffi manifolds and the adapter range were smaller than the ID of the pex tube, so I bought EPDM o-rings that were a little larger to make up the difference. WALLA, worked perfectly.
