Metal-to-metal ôhold in placeö flared type connection

Metal-to-metal ôhold in placeö flared type connection

Metal-to-metal ôhold in placeö flared type connection

(OP)
       I posted this problem on the Piping & fluid mechanics engineering forum, but received no replies. I hope someone here can be of assistance.
     I need specifications and/or tooling to make a metal-to-metal “hold in place” flared type or similar connection. I have seen it used, but do not know how to make it. Fabricated connections are preferred, but a solution using machined parts is acceptable.
     Description - the mating surfaces are similar to a 37 or 45 degree JIC/SAE type flared tube fitting, although the tubing has the male portion (tube is flared inward to accomplish this) and the manifold box has the female portion. (Possibly punched to create the hole and then punched again to create the female flare). The mate is held in place by holding the flared manifold against the flared tube with spring or other type of easily removable hold in place force (No bolts or other more permanent type fastening).
     The application is a washing system with a stationary 1.9” OD flared tube, with a wall thickness of .049, which  has an easily removable rectangular shaped manifold mated tp it. The manifold has a flared hole for the mate. It distributes the flow to 4 tubes that each house spray nozzles. Manifold and tubes are integral and easily removable from the stationary supply tube to facilitate cleaning. Water flow rate is approximately 150 gpm and pressure is about 5 to 7 psi. A small amount of leakage is not a problem.
     Any information on this type of connection or another easily removable mating method, including what it is called, is appreciated.

Do you have any brochure or drawing wher such manifold and system could be see???
Maybe I can help you.

Have you looked into a Marman clamp configuration?  This allows two flat interfaces to be simply clamped together with a ring clamp.  With an embedded o-ring or other seal, it would be leak tight.  I've seen it used for mechanically interfacing sensor turrets as well as diffusion pumps.

1.9 inches happens to be the OD for 1 1/2 inch pipe.  Thread the manifold, cut of a nipple, get some hose, and a couple of clamps.  Without seeing it I wouldn't be sure of what to do.

If you can direct us to a photo, diagram, etc. that will help.  I think what you have described is a 1.9" tube that has the end flaired inward.  So, the flair is more like a machined chamfer?  Is the an intergal part of the device, and the manifold is what is removed?
Picture is worth 10,000 words in this case.
