Companion Flanges

[mover]

Do any of you all use these? I know they are expensive but when you cannot put in a valve and union in an area where it will be covered up, and you have no way to get to the other end of pipe, I use these. Just had a hell of a hard time finding them, and I ended up ordering them just to have them next time I run into this situation.

Not very often, but someday I will get in a situation where a valve and union won’t pass code.

Any comments on these?

I do not know what the type of component you are using actually is the term “Companion Flanges” is unknown to me.

We sometimes but rarely use a joining union that slips over both ends of a gal pipe and has clamping rings with locking nuts on each end – this fitting we call a “viking Coupling” or a “Johnson Coupling” is this the same thing you are speaking of?

Yes. That is what I was talking of. They are work savers in situations where you have two points to work from with no way to gain access from the starting point.

I was just surprised how hard it was to find at the supply houses and even on the www.

The “Viking Couplings” we use down here are a dime a dozen and are nearly always used as a temporary repair – I would never rely upon one for a permanent job finish.
We have them in all sizes and with take off “T’s” cast into them as well – which often become a saviour in difficult situations.
None of these are made in our Country but are imported from the likes of Taiwan etc.
As far as costs per item go they retail here for around $15.00 for 3/4 inch ones.

For compression fittings I feel Ford has the best ( not the auto company the meter box company ) http://www.fordmeterbox.com/pages/coupling.htm
For gas piping however I always either use reverse thread nipple and coup. or make up a section with CSST. I do think you would find the quality of the joint on the Ford couplings far superior to most.
