I like the tape as I can slit it and swap out easily.? When I was doing piping the Blastgate Co fittings were undersized and inside on both ends.? I don't know if that is still the case ( couldn't access their website ).? I had the bast luck with Oneida and
Kencraft fittings but every once in a while one was oversized a little.? Dave

I have actually regretted using the tape instead of a sealant…?

?You should expect any wye, blastgate or union to accept spiral pipe of same dimension to slip right over. Perhaps a little pushing/twisting, but nothing too tough.?
That being said, I recently expanded, adding a wye and more new spiral pipe. They did not get along. Contacted seller (Blastgateco.com), whom I've dealt with for years, and asked what changed - is there a new sleeve required between these pieces now? Pipe and
nipple on wye were precisely the same size.? I manipulated (slit) offending wye to expedite the job. Seller response:
No, nothing's changed, should not need to do this, and refunded me the full purchase price of offending piece.?
So:
1- Expect? spiral pipe to slide reasonably well onto Wyes, Elbows, unions and blastgates. Always has been and currently should be the case - just try to buy all from same source.
2- Contact your vendor if experiencing problems
3- Once properly fit, use a few self-tapping sheet metal screws, and seal with
actual duct tape, like Nashua 357, which will stick and stay put. You'll find it at local Hdwe store, sometimes with stove pipe fittings, as it has a high heat rating. Resist temptation to apply silicone or other sealants, or you'll regret it next time
you go to re-configure system.?
Good luck!

I appreciate all the comments in this thread. I am using the correct materials and understand how to put it together, but I am having the exact issue that Jeff describes, and yes, the materials I ordered came from Blastgate also. They were terrific about making up some metric sized fittings for me, and I’ll contact them again as I work through the whole project. I do think there are specific offending pieces—some sleeves meant to put two fittings together. Some fit and some don’t.
Yesterday, I spent a few hours and applied some Try Hard and managed to sort through the various parts and have more success. So with all the encouragement and a dose of patience, I think I’ll get ‘er dun. Probably another order from Blastgate, too.

I did find the occasional tight fitting or dented pipe… so a block of wood and a ball peen hammer and you can flare and stretch the metal slightly to help with assembly. I do have the crimping tool that puts the ribs in the pipe to shrink it down, but the heavier stuff doesn’t react to that very well and unless the airflow is going in the right direction I’d rather expand than contract the material to get it to fit.

My go to sheetmetal tool for any cut off work is a Matebo? 4.5 right angle grinder with 1/32 “ by 6” cut off blades nothing else matches up. An anvil comes in pretty handy along with heavy pipe to beat on the material to expand. I tend to build assemblies van stone the ends and ring flange. mac,,, Designing and building for 50 years
