Fitting JG speedfit T's to non JG 22m pipe

[Swell1]

Hello, I've ran JG speedfit 10mm pipe from new radiators up to the 22m plastic flow and return.
The flow and return is 22mm plastic (not JG Speedfit).
Can I still add my JG T's to the non JG pipe? And do I use JG inserts?
Many thanks

The fittings are ok ,inserts may vary

It would be normal to use the pipe's own make of insert

Thank you, I have no idea what manufacturer the 22mm pipe is, its been in the property for a number of years.

No markings on the pipe I take it?

Hello, in the loft its 15mm gray plastic pipe (apologies in comes down to a 22mm).

I need to T in to this gray 15mm with JG speedfit 10mm pipe.

Would I use JG 15mm inserts on this pipe or something else?

Any advice appreciated.

Hep²O is my guess. No other markings visible?

15mm hep equal tee with a jg 15-10mm stem reducer in the middle of the T to come off that in Speedfit.
